When signing a transaction will result in the sighash single bug being
exploitable we should return the 'one array' (equivalent to 1 as a
uint256) as the signature hash.
Add a unit test to verify we return uint256 1 value when use of
SIGHASH_SINGLE is invalid.
When signing a transaction will result in the sighash single bug being
exploitable we should return the 1 array (equivalent to 1 as a uint256)

Currently we are using the correct array value but are re-hashing it,
instead we should directly return it.

Sorry to be a bore and request review on all these docs fixes, this one is all in a single patch which makes it a bit harder to review. It is very similar in content to all the others that are open right now so I'm going to be a bit rude and leave it like this.

The line of code `let mut have_witness = self.input.is_empty();` is
puzzling if one does not know _why_ we serialize in BIP141 style when
there are no inputs.
Add a code comment to save devs spending time trying to work out _why_
this is correct.
The two methods `encode_signing_data_to` and `signature_hash` use the
same docs (one is a public helper for the other). The docs have gotten a
bit stale (refer to deprecated types).
Instead of duplicating all the text, add a statement pointing readers
from the docs of `signature_hash` to the docs on
`encode_signing_data_to`.
Improve the rustdocs for the `blockdata::block` module:
- Use full sentences (capitalisation and full stop)
- Use third person tense instead of imperative
- Improve wording if needed
Currently function contains nested `if` clauses that arguably obfuscate
the code. We can make the code easier to read by pulling out the error
paths and returning them higher up in the function.
Refactor only, no logic changes.
Put the calls to `impl_hashencode` in the same order, and with the same
whitespace, as the calls to `hash_newtype`. This makes groking the file
easier because its quick to glance down the types and see which ones
implement hashencode (consensus_encode/decode) and which ones do not.
Changes the API from TweakedPublicKey to XonlyPublicKey. I believe we
introduced TweakedPublicKey to guard against creating address API. This
is confusing because when we want to verify control block we have to
call dangerous_assume_tweak.
This is in true in most cases that the key would be tweaked, but we only
want to guard in while creating a new address. If we want to verify
blocks, we should deal with native X-only-keys regardless of how they
were created
5e2449922d Separate merge logic out of Map trait (Tobin Harding)

Was following #520 and through it was a quick fix that I could do:
#### Changes:
- If an uncompressed public key doesn't have prefix 0x04 in `PublicKey::from_slice()`, an error is returned.

I was wondering if `PublicKey::from_str()` should also enforce the same rules, however I have not incuded this in the PR.

Recently we (*cough* Tobin) made the `Map` trait private and neglected
to add a public API for combining together two PSBTs. Doing so broke the
`psbt` module.
Pull the merge logic out of the `Map` trait and put it in methods on
each individual type (`Input`, `Output`, `PartiallySignedTransaction`).
Doing so allows for simplification of return types since combining
inputs/outputs never errors.
Use the term 'combine' instead of 'merge' since that is the term used in
BIP 174.

This changes the type of secp signature from secp256k1::Signature to

as well as uncompressed keys. This bug was introduced in #591 while
trying to change the type of BIP32 keys from bitcoin::PublicKey to
secp256k1::PublicKey.

Pull request description:
This PR tries to do a minimally-invazive separation of signature- and key-related types, previously mixed in a single `util::ecdsa` module.
Rationale: bitcoin key types are not specific for signature algorithm. See discussion at #588.
This PR became possible after we moved on new `secp256k1` version exposing `XonlyPublicKey` type, since now all key types may co-exist in a single module under different names
The PR goal is achieved through
- Renaming ecdsa mod into private ec module such that the code is not copied and diff size is small;
- Introducing dummy ecdsa mod back in the next commit and re-exporiting only signature types from internal `ec` mod in it;
- Re-exporting all key types under `key` module, removing previous depreciation message for bitcoin keys.

The method implementation of `insert_pair` is currently not used for
`PartiallySignedTransaction`. Having an implementation available is
deceiving.
Delete the unused `insert_pair` code from
`PartiallySignedTransaction` (dead code). Make the `insert_pair` methods
from `Input` and `Output` be standalone functions.
The `Map` trait has been deemed confusing and not that useful to users
of the library, we still use it internally within the `psbt` module
though so make it visible only in `psbt` and `psbt::map`.
Improve the function rustdocs in the `psbt::map` module by:
- using third person tense as is idiomatic in the Rust ecosystem
- using rustdoc `///` not code comments `//` for methods
- Use `# Return` section for documenting return values
Done for this module only as part of a PR fixing code within this
module.

This commit tries to achieve separation of signature- and key-related types, previously mixed in a single ECDSA module.
Rationale: bitcoin key types are not specific for signature algorithm.
This is achieved through
- Remove key mod with its content moved to ecdsa mod
- Re-export keys under key module in util mod - to make git generate diff for the rename of ecdsa mod in the next commit correctly.

I think it is more natural to write Wintess::new() followed by Witness::push()
then Witness::default(). In any case, there is no harm in having additional constructors.

In the first two commits I moved some data from source files to the newly introduced `test_data` dir, including it with `include_[str|bytes]!` macro.
The second-to-last commit introduces a big block in test_data which is very handy in ser/de benchmark (I used it for #672) because with smaller blocks you may not notice performance improvements.
Since I don't want to pollute the package the last commit excludes the `test_data` dir from the published package. I think it's fine to do it because dependent packages don't run dependencies tests.

Pull request description:
`StreamReader` performance is extremely poor in case the object decoded is "big enough" for example a full Block.
In the common case, the buffer is 64k, so to successfully parse a 1MB block 16 decode attempts are made.
Even if a user increases the buffer size, `read` is not going to necessarily fill the buffer, as stated in the doc https://doc.rust-lang.org/stable/std/io/trait.Read.html#tymethod.read. In my tests, the reads are 64kB even with a 1MB buffer.
I think this is the root issue of the performance issue found in electrs in https://github.com/romanz/electrs/issues/547 and they now have decided to decode the TCP stream with their own code in cd0531b8b7 and 05e0221b8e.
Using directly `consensus_encode` seems to make more sense (taking care of using `BufRead` if necessary) so the `StreamReader` is deprecated

StreamReader before this commit is trying to repeatedly parse big object like

106acdc3ac Add fuzzing for Witness struct (Riccardo Casatta)
2fd0125bfa Introduce Witness struct mainly to improve ser/de performance while keeping most usability. (Riccardo Casatta)
Pull request description:
At the moment the Witness struct is `Vec<Vec<u8>>`, the vec inside a vec cause a lot of allocations, specifically:
- empty witness -> 1 allocation, while an empty vec doesn't allocate, the outer vec is not empty
- witness with n elements -> n+1 allocations
The proposed Witness struct contains the serialized format of the witness. This reduces the allocations to:
- empty witness -> 0 allocations
- witness with n elements -> 1 allocation for most common cases (you don't know how many bytes is long the entire witness beforehand, thus you need to estimate a good value, not too big to avoid wasting space and not too low to avoid vector reallocation, I used 128 since it covers about 80% of cases on mainnet)
The inconvenience is having slightly less comfortable access to the witness, but the iterator is efficient (no allocations) and you can always collect the iteration to have a Vec of slices. If you collect the iteration you end up doing allocation anyway, but the rationale is that it is an operation you need to do rarely while ser/de is done much more often.
I had to add a bigger block to better see the improvement (ae860247e191e2136d7c87382f78c96e0908d700), these are the results of the benches on my machine:

With an increased performance to deserialize a block of about 21% and to serialize a block of about 16% (seems even higher than expected, need to do more tests to confirm, I'll appreciate tests results from reviewers)

2959e04ebd Allow specifing a raw `TapLeafHash` in sighash computation (Alekos Filini)
Pull request description:
Still need to add some tests but the code should be ready for review. Please let me know if you have better ideas for the enum naming.
---
Instead of always requiring the full raw script and leaf version, allow
just specifying a raw leaf hash to the sighash computation functions.
This is very useful when dealing with PSBTs, because the
`PSBT_IN_TAP_BIP32_DERIVATION` field only maps a public key to a leaf
hash, so a signer could just take it and produce a signature with it
rathern than having to jump through hoops to recover the full raw
script.

Witness struct is in place of the Vec<Vec<u8>> we have before this commit.
from_vec() and to_vec() methods are provided to switch between this type and Vec<Vec<u8>>
Moreover, implementation of Default, Iterator and others allows to have similar behaviour but
using a single Vec prevent many allocations during deserialization which in turns results in
better performance, even 20% better perfomance on recent block.
last() and second_to_last() allows to access respective element without going through costly Vec
transformation

There is no reason to force users to use one particular form when
providing a denomination string. We can be liberal in what we accept
with no loss of clarity.
Allow `Denomination` strings to use a variety of forms, in particular
lower case and uppercase.
Note, we explicitly disallow various forms of `Msat` because it is
ambiguous whether this means milli or mega sats.

First patch is cleanup. Here is the commit message for the second patch
```
The merkle_root of an empty tree is undefined, this is the only error
case we have for the two `bitcoin_merkle_root*` functions. We can fully
describe this error case by returning an `Option` if args are found to
be empty.
While we are at it, refactor out a recursive helper function to make
reading the code between the two functions easier.

```
This code is currently minimal to aid reviews. We can at a later point implement (Encodeable, psbt::Serialize, FromHex, ToHex) etc in follow-up PRs.

We have two types for tweaked/untweaked schnorr public keys to help users of the taproot API not mix these two keys up. Currently the `taproot` module uses 'raw' `schnoor::PublicKey`s.
Use the `schnoor` module's tweak/untweaked public key types for the `taproot` API.
Fixes: #725
Please note, I saw this was labeled 'good-first-issue' but I ignored that and greedily implemented a solution because of two reasons
1. We want to get taproot stuff done post haste.
2. I'm struggling to follow what is going on with all the taproot work so this seemed like a way to get my hands dirty.

This builds on https://github.com/rust-bitcoin/rust-bitcoin/pull/699 but is the more bikesheddable part since it changes the API.

Currently we calculate the parity during `tap_tweak` but do not return
it, this means others must re-do work done inside `tap_tweak` in order
to calculate the parity. We can just return the parity along with the
tweaked key.
Keeping inline with the method on `UntweakedPublicKey` that outputs a
`TweakedPublicKey` we can use the same name, for the same reasons.
Use `dangerous_assume_tweaked` as the constructor name to highlight the
fact that this constructor should probably not be being used.
We currently run `tweak_add_check` and use the result as a conditional
branch, the error path of which uses `unreachable`. This usage of
`unreachable` is non-typical. An 'unreachable' statement is by
definition supposed to be unreachable, it is not clear why we would need
to have a conditional branch to check an unreachable statement.
Use `debug_assert!` so programmer errors get caught in un-optimised
builds but in optimised builds the call to `tweak_add_check` is not even
done.
We have two types for tweaked/untweaked schnorr public keys to help
users of the taproot API not mix these two keys up. Currently the
`taproot` module uses 'raw' `schnoor::PublicKey`s.
Use the `schnoor` module's tweak/untweaked public key types for the
`taproot` API.
The merkle_root of an empty tree is undefined, this is the only error
case we have for the two `bitcoin_merkle_root*` functions. We can fully
describe this error case by returning an `Option` if args are found to
be empty. We can do the same for the wrapper functions in `block`
module.
While we are at it, refactor out a recursive helper function to make
reading the code between the two functions easier.
04a8f89f05 Implement `FusedIterator` for `Instructions` (Martin Habovstiak)
Pull request description:
`Instructions` guarantee to return `None` from empty iterator so we
should signal this in type system so that the code can be optimized
better. This also adds a test to make sure this property holds.

Pull request description:
Calls to `unwrap` outside of tests are generally unfavourable. We currently call `unwrap` in a bunch of places on calls to `consensus_encode` when passing writers that do not fail.
Remove `unwrap` calls on all calls to `consensus_encode` that pass a writer argument for which write functions do not fail. Use `expect` with a descriptive string instead.

Calls to `unwrap` outside of tests are typically unfavourable.
In memory writers (`Vec`) do not error. We can use `expect` with a
descriptive message string to indicate this.
