d099b9c195 Remove wildcard from prelude import (Jamil Lambert, PhD)
Pull request description:
This patch replaces `prelude::*` wildcard imports with the types actually used. In a couple of cases `DisplayHex` was previously imported by the wildcard but was only used in the test module, an additional import was added to the test module instead of at the top where it causes an unused import warning.

cf800a1b07 Remove bech32 dependency from blockdata (Tobin C. Harding)
Pull request description:
We have a single usage of the `bech32` crate inside the `blockdata` module, to convert a `WitnessVersion` to a `Fe32`. We then have a single call site where we use the conversion in the `address` module.
This code was written without thinking to hard about the introduced dependency on `bech32`, in hindsite it shouldn't have been added.
In preparation for splitting a bunch of code in `blockdata` out into the `primitives` crate remove the `bech32` stuff from the `witness_version` module.

This is a continuation of the previous commit, but separated to make
review a little easier. This one replaces test vectors that were
previously computed by hashing garbage into Txids and various other hash
types with new test vectors which are directly-computed garbage
converted to hashes with from_byte_array.
In one case (src/hash_types.rs) this results in changing a bunch of
fixed test vectors. This is okay; this test is supposed to check the
direction of string serialization, which is unaffected by this commit
(or any commit in this PR). The existing test vectors, because they hash
the empty string, result in different bytes depending on the underlying
hash algo (sha256, sha256d, sha256t, etc). The new ones just use the
same fixed test vector for all of them.
This commit also updates a doctest in crypto/sighash.rs which
demonstrates how to manually feed sighash data into a hash engine and
correctly handle the sighash single bug. Because you can no longer
directly get a sighash object from an engine, this particular example
should maybe be rewritten to just encode to a Vec rather than a hash
engine, explaining that maybe you'd do this when implementing a HWW, to
verify the exact data being hashed. Or something.
Unrelatedly, you can check that there are no API changes in this commit
or the last several. The next commit will remove GeneralHash impls and
that's when you'll see changes.
In the next commits we are going to stop exposing the ability to hash
arbitrary data into wrapped hash types like Txid etc. In preparation for
this, stop using these methods internally.
This makes our internal code a little bit uglier and less DRY. An
alternative approach would be to implement the from_engine and engine
methods, but privately (and maybe having a macro to provide this). But I
think this approach is more straightforward.
The one exception is for the Taproot hashes, which are tagged hashes and
currently do not have their own engine type. I will address these in a
later PR because this one is already too big.

c71ae9ac16 Move PushBytes::read_scriptint (Tobin C. Harding)
Pull request description:
The `push_bytes` module has a `private` module that exists solely to protect the invariant on the `PushBytes` inner byte slice. There is a `PushBytes` impl block outside the private module for functions that can not and do not violate the length invariant.
Recently we move the `read_scriptint` method to be on the `PushBytes` but we put it inside the `private` module, since the method only reads off of the slice it cannot invalidate the invariant and does not need to be inside the `private` module.
Move the `read_scriptint` method outside of the `private` module to keep that module as small as possible, helping with its stated aim of being the only place that requires auditing.
Patch 2 is whitespace only.

We use 100 column width for rustdoc in this project, while not a super
hard rule the docs on `read_scriptint` are long, using the 100 column
width reduces the line count a reasonable amount.
No text changes, only whitespace.

the `blockdata` directory is code organisation thing, all the
types/modules are re-exported from other places. In preparation for, and
to make easier, the `primitives` crate smashing work - remove all
explicit usage of `blockdata`.
Note that the few instances remain as they seem required e.g.,
`pub(in crate::blockdata::script)`
Refactor only, no logic changes.
e7f33a2a12 Update PushBytes::read_scriptint(x) to x.read_scriptint() (Shing Him Ng)
Pull request description:
Fixes#2849
There were a few other usages of PushBytes::read_scriptint(_) in the tests such as [this](406e3486ab/bitcoin/src/blockdata/script/tests.rs (L315)), but they couldn't be updated as cleanly as the changes in this PR.

There are two limits that the Bitcoin network enforces in regard to
hashing scripts
- For P2SH the redeem script must be less than 520 bytes
- For P2WSH the witness script must be less than 10,000 bytes
Currently we are only enforcing the p2sh limit when creating an address
with `Address::p2sh`.
There are various ways to create addresses from script hashes and if
users manually hash a script then use the `ScriptHash` (or
`WScritpHash`) our APIs assume the script that was hashed is valid. This
means there is the potential for users to get burned by creating
addresses that cannot be spent, something we would like to avoid.
- Add fallible constructors to `ScriptHash` and `WScriptHash`
- Add `TryFrom` impls as well to both types
- Remove the `From` impls
The script in a p2wsh is typically referred to as the witness script not
the redeem script - rename the local test variable to follow suit.
Refactor only, no logic changes.
This test does an odd combination of function calls, its not obvious
what it is supposed to be testing. The `to_p2wsh.is_p2wsh` is already
tested above. The leading `to_p2sh` does not prove anything, one can put
currently pass any script to `to_p2wsh` so this tests nothing.
In preparation for patching the script hashing functionality first
remove this odd test.

Currently we have a trait `Hash` that is required for `Hmac`, `Hkdf`,
and other use cases. However, it is unegonomic for users who just want
to do a simple hash to have to import the trait.
Add inherent functions to all hash types including those created with
the new wrapper type macros.
This patch introduces some duplicate code but we are trying to make
progress in the hashes API re-write. We can come back and de-dublicate
later.
Includes making `to_byte_array`,`from_byte_array`, `as_byte_array`, and
`all_zeros` const where easily possible.
The deprecation notice for `is_provably_unspendable` contains "is not
very useful" which is a bit presumptuous to tell to users, it may very
well be useful to them. Use the more helpful text that already exists in
rustdoc on the function.

Pub back in deprecated `dust_value`, linking to the rename.
These two functions are related. We cannot, by definition, get the
witness version from a script that is not a witness program but
currently the code is not linking these two things.
Refactor by doing:
- Move the check of the witness program bip rules to `witness_version`
- Call `witness_version().is_some()` in the predicate
Improve the docs while we are at it to include the bip text in the
rustdoc. Note I didn't bother referencing the segwit bip number, this
bip text is pretty well known.
Add two unit tests that verify we can correctly determine if a
shortest allowed and longest allowed script is a witness program.
Done in preparation for patching the `witness_version` function.

Add two public API functions on the two public keys, both called
`p2wpkh_script_code` to do exactly as the name suggests.
Of note, I was not able to find anywhere to use these in example code,
this is because of we always use the new `p2wpkh_signature_hash`
function. The new functions may be useful for a user calling
`segwit_v0_encode_signing_data_to`. The may help document the library as
well.
