We can use `package` to rename `bitcoin_hashes` to `hashes` and
`bitcoin_internals` to `internals`. This makes imports more terse with
no loss of meaning.
This improves readability of converting `BlockHash` into `ChainHash`.
It's useful in e.g. Electrum protocol which sends `BlockHash`
(serialized backward).

All non-trivial formatting is done in separate patches so the changes can be verified mechanically.
With this applied the whole `rust-bitcoin` crate will be formatted.
Big thanks to everyone for putting up with the ongoing formatting PRs, no-one likes doing these but hopefully this an improvement to the project - especially in helping us get more contributors to the project.

Add `rustfmt::skip` attribute in a couple of places and then remove the
exclude for the `blockdata` module. Do not run the formatter, that will
be done as a separate patch to aid review.
Currently we have a code comment that is supposed to assist devs in
maintaining the `network::constants::Network` type by failing to build
if a new variant is added. This plays havoc with the formatter because
the comment is hanging at the bottom of a match block and the formatting
thinks its for the proceeding line of code.
Instead of using a code comment add a panic so the unit test fails if a
new variant is added to `network::constants::Network`.

d56d202aeb Support weight prediction in `const` context (Martin Habovstiak)
Pull request description:
**Notes for reviewers:**
This is something that I want to use in my code and hopefully reasonably easy to review, so if this can get into 0.30 that'd be really nice. No hard feelings if it doesn't.
I tried to put extra effort into making review easier by:
* intentionally "mis-formatting" the first commit so diff is smaller and easy to understand - see individual commits.
* copying patterns from non-const fn to const fn so it's obviously correct (includes same variable names)
* not bothering with the array trick in `VarInt::len` and simply accepting the limitation of Rust 1.46+ (I use 1.48 BTW).
**Description**
Some smart contracts or simplified wallets statically know the sizes of
transactions or inputs. The possible approaches to handling them so far
were re-computing the values (and hoping the optimizer will const fold
them) or using a simple constant which may be harder to understand and
get right. It's much nicer to just use a `const` but our code didn't
support it until now.
This change adds methods that can compute the prediction in `const`
context for Rust versions >= 1.46.0 which allow use of loops (and
conditions but those could be workaround anyway).
As a side effect of this, the change also adds `const` to `VarInt::len`
in Rust 1.46+. While this one could be made unconditional using array
trick it's probably not worth it because of the planned MSRV bump.

There are several common spends in Bitcoin that have known input weight
predictions. It can be useful to have these as constants, so this change
adds them. However, this only adds native segwit ones as the others are
slowly fading away and might clutter the API.

Currently we have an associated type on hash types `Inner` with
accompanying methods `into_inner`, `from_inner`, `as_inner`. Also, we
provide a way to create new wrapped hash types. The use of 'inner'
becomes ambiguous with the addition of wrapped types because the inner
could be the inner hash type or the `Inner` byte array of the inner
wrapped hash type.
In an effort to make the API more clear and uniform do the following:
- Rename `Inner` -> `Bytes`
- Rename `*_inner` -> `*_byte_array`
- Rename the inner hash to/from methods to `*_raw_hash`
Correct method prefix `into_` -> `to_` because theses methods convert
owned `Copy` types.
Add the trait Bound `Copy` to the `Bytes` type because we rely on this
trait bound for the conversion methods to be correctly named according
to convention.
Because of the dependency hole created by `secp256k1` this patch changes
the secp dependency to a git tag dependency that includes changes to the
hashes calls required so that we can get green lights on CI in this
repo.

It may not be obvious why the condition in `push_bytes` module checks
for negation of 16 and 32 bit architectures rather than 64 bit. This
adds a comment about it being conservative.
Currently we have `TapSighash` that is used for taproot sighashes but
for non-taproot sighashes we use `hash_types::Sighash`. We can improve
the API by creating a `LegacySighash`, and `SegwitV0Sighash`.
Copy the original `Sighash` macro calls to create the two new types in
the `sighash` module.
While we are at it, put the `TapSighash` and `TapSighashTag` into the
`sighash` module also.
Script parsing is composed of several functions which implicitly rely on
various properties. Adding a type that restricts the valid values makes
local review easier.
So far we deserialized hex into `Vec<u8>` at run time. This was mainly
in tests where it had negligible performance cost. However moving the
computation to compile time has a few benefits: it allows proving the
length of the decoded bytes and identifies potential typos before the
code goes through LLVM and other compilation machinery which makes
feedback faster.
This change uses the `hex_lit` crate to move computation to compile
time. It is implemented as `const` declarative macro which doesn't blow
up compilation time.
An absolute lock time of 100 is nonsensical because we are well past
block 100. This value was used because it makes sense for _relative_
locktimes but for absolute lock times it makes the examples and tests
slightly confusing.
272cdbcf7c Flatten the types directory (Tobin C. Harding)

cf068d16b0 Implement transaction weight prediction (Martin Habovstiak)
Pull request description:
When creating a transaction one must know the the fee beforehand to set
appropriate amounts for outputs and to know the fee, weight is required.
So far we only had a method on an already-constructed transaction. This
method clearly wasn't helpful when constructing the transaction except
for hacks like temporarily adding an all-zeroes signature.
This change adds a function that can compute the transaction weight
without knowing individual bytes of the scripts, witnesses and other
elements. It only needs to know their sizes.
To make the API less error-prone a special, trivial, type is also added
for computing the lengths of witnesses.

Move code from `types/mod.rs` to `script/mod.rs`, move the two

In some cases people construct the transaction with a dummy fee output
value before calculating the weight. A method to create the iterator
over `script_pubkey` lengths is useful in such cases.
In some scenarios it's useful to create outputs with minimal relayable
value. E.g. outputs designated for fee bumping using CPFP. A method for
this is useful.
This implements a constructor of `TxOut` that computes the minimal
non-dust value from the passed script.

Currently we implement string parsing for height/time from the
`absolute` module but not the `relative` module.
Improve the macros used to implement string parsing and use the new
versions to implement string parsing for the height and time types in
`relative`.
Lock times are u32 and can necessitate encoding using 5 bytes. As such
they are "special".
Add methods `push_lock_time` and `push_sequence` for pushing absolute
lock times and sequence numbers. We do not push relative locktimes
because they are only 16 bits from the original sequence number.
Our `script::read_scriptint` function is based on the constructor
code (incl. call to `set_vch`) code from Bitcoin Core. Add rustdoc
comment saying so, emit a link because there are already multiple links
to `script.h` in this file (one just right below the added comment).
We only support reads of upto 4 bytes where as Bitcoin Core allows
reading a `CScriptNum` with more bytes than that. Add a rustdoc
comment (incl. link to Bitcoin Core) mentioning that.
Our `Builder::push_int` method is the same as Bitcoin Core `CScript`
`push_int64` method. We currently use `OP_FALSE` (equivalent to `OP_0`)
but recently we added `OP_0`, lets use it to make our code better mimic
Core (also saves devs checking that `OP_FALSE` is the same as `OP_0`).

The `script` module is large and unwieldy.
Refactor the `script` module, splitting it up into a tree of modules.
Here are a few of the changes and their stated benefits
- Split the two script types out into separate files: Readers of the
methods can then tell immediately from the file name which type they are
reading.
- Put all the impls for the two script types together: Makes parsing the
API easier because one can more quickly see which traits are implemented
on what i.e., all the `AsRef` imlps are grouped together.
- Put the impls for the two script types in order, first `Script` then
`ScriptBuf`: Makes it easier for us to see if we missed something.
- Put the `Builder` and `Instruction` (and associated) types in their
own modules: Some devs find long files hard to navigate, so far there
hasn't been too much push back against short files.
- Put tests in a separate file: This idea was recently discussed.
This is only moving code and fixing import statements etc. No other
changes to the code.

We can improve ergonomics of the `script` module by implementing the
`fmt` traits on `ScriptBuf`, trivial because we can call through to the
`Script` implementations.
The `max_value` and `min_value` functions only exist to be
compatible/uniform with Rust 1.41.1 they will never change and they just
return a constant value. They can therefore be made const functions.
Some of the lock time structs (`Height`, `Time` ect.) are missing
standard constants for min, max ect.
Add standard constants taking into consideration the various locktime
corner cases.
Add `max_value` and `min_value` to be consistent with Rust 1.41.1 (incl.
`Sequence`).
Fix: #1451
a762a89b48 Add documentation to Sequence::is_final (Tobin C. Harding)
b1490a26ea Move enables_absolute_lock_time method (Tobin C. Harding)
Pull request description:
The term "final" is an archaic Bitcoin term however it is well used, it exists in Bitcoin Core code as well as in various bips. To help folks new to Bitcoin add documentation to the `is_final` method including historical notes.
Note, this does _not_ deprecate `is_final` - while writing the notes I found the term "final" in enough official places that I think its fair game to keep the term, some things people just have to learn, we can definitely help with that learning though.

8c0e5213d3 Delegate debug for ScriptBuf to Script (Tobin C. Harding)
Pull request description:
Currently the derived implementation of `Debug` for `ScriptBuf` prints the inner vector of u8s as integers, this is ugly and hard to read. The `Script` implementation of `Debug` prints the script opcodes and data as hex, we can just delegate to it.
With this applied we get debug output of form:
Script(OP_DUP OP_HASH160 OP_PUSHBYTES_20 3bde42dbee7e4dbe6a21b2d50ce2f0167faa8159 OP_EQUALVERIFY OP_CHECKSIG)

Addresses with Segwitv0 not having len 20/32 are invalid and cannot be
constructed. Also cleans up a API bug in
ScriptBuf::new_witness_prog(ver, prog) allowing prog of invalid lenghts.

exists in Bitcoin Core code as well as in various bips. To help folks
new to Bitcoin add documentation to the `is_final` method including
historical notes.
In preparation for deprecating the `is_final` method; move the
`enables_absolute_lock_time` method to be directly above the `is_final`
method.
Refactor only, no logic changes.

We use `internals::hex::display::DisplayHex` in many places, we can
improve ergonomics of the `internals` crate by re-exporting it from the
`prelude` module.
The `ToHex` trait was replaced by either simple `Display`/`LowerHex`
where appropriate or `DisplayHex` from `bitcoin_internals` which is
faster.
This change replaces the usages and removes the trait.

089a1e452d Replace `Vec::from_hex` with `hex!` (Martin Habovstiak)
Pull request description:
This makes the code less noisy and is a preparation for changing it to `const`-based literal. Because of the preparation, places that used variables to store the hex string were changed to constants.
There are still some instances of `Vec::from_hex` left - where they won't be changeable to `const` and where `hex!` is unavailable (integration tests). These may be dealt with later.
See also #1189
Note that while the change appears big it's nearly entirely mechanical, so should be pretty easy to review. (But I don't feel it's `trivial`.)

The additional `use` items were added to improve the style of
documentation. Because they were only used for doc they were `cfg`ed.
But because this is independent from being built by `docs.rs` the `cfg`
should've been `doc` not `docsrs`.
IOW `docsrs` means roughly `all(doc, nightly)` and the added items are
unrelated to `nightly`.

Add `#[inline]` to all public functions/methods excluding error types
and `Display` impls. Error paths do not need to be fast and presumably
`Display` is called on code paths that do IO so this also does not need
to be fast.

a7f3458c27 Fix bug in `ScriptBuf::extend` for short iterators (Martin Habovstiak)
Pull request description:
`ScriptBuf::extend` contained an optimization for short scripts that was
supposed to preallocate the buffer and then fill it. By mistake it
attempted to fill it from already-exhausted iterator instead of the
temporary array it drained the items into. This obviously produced
garbage (empty) values.
This was not caught by tests because the optimization is only active for
scripts with known maximum length and the test used `Instructions` which
doesn't know the maximum length.

This is useful when one already has bytes allocated in a vec that can be
reused.
The change also documents that the mirror method `into_bytes()` doesn't
allocate.
