4a119e5624 Re-export blockdata modules (Tobin C. Harding)
Pull request description:
In an effort to make the library more ergonomic to use re-export modules from `blockdata` at the crate root level. This helps to decouple the internal code layout with the public API.

34f955a073 Introduce new canonical license blurb (Tobin C. Harding)
Pull request description:
Recently we introduced SPDX license ids but there was some confusion
about the use, form, and purpose of lines before (library name, author).
It was pointed out to me by Andrew that if/when folks cut'n'paste our
code they often will keep the whole blurb. Design it with that in
mind. FTR, Andrew also indicated that he did not mind his name being
removed in favour of "The rust-bitcoin developers".
At first I thought the term "The rust-bitcoin developers" was a bit
wishy-washy but yesterday I realised that I am proud to be part of that
crew, striving to deliver code to the highest possible standard.
Introduce a canonical format for the licences blurb.
- Use the name of the library

cc2c67fc2d Move sighash types to the sighash module (Tobin C. Harding)
7c040f4437 Refactor imports (Tobin C. Harding)
29f21d6ff5 Add additional sighash related pubic exports (Tobin C. Harding)
Pull request description:
This is non-urgent work, something I've wanted to do for months now, please only review at your leisure :)
Currently we have a bunch of sighash types defined in the `transaction` module and we have a newer `sighash` module that defines a bunch of related types. This is an artifact of the development process as we added the new types. If we put things that are related together it makes it easier for devs to find their way around the library and grok the code.
Move all the sighash types from the `blockdata::transaction` module to the `sighash` module.
The first two patches are preparatory cleanup.
### Labels
I added "API break" because I move the types without adding a re-export from the original place. I believe this is correct because we are, hopefully, aiming to de-couple the public API from the internal module structure so there is going to be a load more of this.

Pull request description:
Do error cleanups, and add a script to help find missing `non_exhaustive` on error types
- Patch 1: Audit the codebase and put `non_exhaustive` on all error types.
- Patch 2: Implement `std::error::Error::source` for `bip152::Error`
- Patch 3: Implement `Display` and `std::error::Error::source` for `MerkleBlockError`
- Patch 4: Move rustdocs to above attributes on one error type
- ~Patch 5: Add a python script to `contrib` that checks the codebase for missing non exhaustive on the line above the results of regex `pub enum .*Error`~
I removed the Python script patch, I can't be bothered working on this for now but the clean ups and `non_exhaustive` additions are useful IMO.
### labels
- I added 'API break', I think the `non_exhaustive` addition requires major bump but not sure?
- release notes mention is just for the `non_exhaustive` patch.

Currently we have a bunch of sighash types defined in the `transaction`
module and we have a newer `sighash` module that defines a bunch of
related types. This is kruft from the development process as we added
the new types. If we put things that are related together it makes it
easier for devs to find their way around the library and grok the code.
Move all the sighash types from the `blockdata::transaction` module to
the `sighash` module.
Refactor only, no logic changes.
The identifier 'util' does not convey any information. We have a whole
bunch of modules inside the `util` module.
As part of work to reduce the amount of arbitrary things in the `util`
module move the `address` module to the crate root level.
We have a bunch of clippy warnings on master, at least one of them is
from a patch dated from March, before we ran clippy on CI.
Fix clippy warnings
- warning: accessing first element with `self.0.get(0)`
- warning: deref on an immutable reference
- warning: you are deriving `PartialEq` and can implement `Eq`
All one patch because clippy has to run cleanly for each patch on CI
now.
Please note the `Eq` change, adding this derive is an API change.
When we introduced the `SighashCache` we put encoding and sighash code
for segwit (v0 and taproo) in the `sighash` module. We also added
methods for legacy inputs that wrapped calls to encode/sighash methods
in the `transaction` module. This is confusing for a couple of reasons
- When devs read `Transaction` there are two methods that apparently
enable encodeing tx data and calculating the sighash but there is no
indication that these methods are only for legacy inputs.
- Ocne devs work out that segwit inputs have to be handled by methods on
the `SighashCache` it is not obvious why the methods on `Transaction`
exist at all.
Move the legacy encode/sighash code over to the `sighash` module and
deprecate the old methods. (Includes moving unit tests.)
This is follow up work to the recent addition of the `Sequence` type. We
do not need to keep a public integer const for `MAX_SEQUENCE` because we
offer the `Sequenc::MAX` associated type.
Use the all-bits-set u64 directly in the associated type `Sequence::MAX`.
Error variants should not end with the same identifier as the enum,
i.e., they should not stutter.
Found by clippy after setting:
avoid-breaking-exported-api = false
Clippy gives a warning about `wrong_self_convention` because we consume
self in a method called `is_*`. We have to consume self because the
object has a generic `E` (error type) that does not implement `Copy`.
Turns out by default clippy does not lint certain parts of the public
API. Specifically, by setting
avoid-breaking-exported-api = false
we can get clippy to lint the public API for various things including
`wrong_self_convention`.
Clippy emits:
warning: methods with the following characteristics: (`to_*` and `self`
type is `Copy`) usually take `self` by value
As suggested, take `self` by value for methods named `to_*`.

`Sequence` didn't have `FromStr` nor `TryFrom<{stringly type}>`
implemented by accident. This moves a macro for implementing them from
`locktime` module to the `parse` module, renames it for clarity and uses
it to implement parsing for `Sequence`.
When debugging parsing errors it's very useful to know some context:
what the input was and what integer type was parsed. `ParseIntError`
from `core` doesn't contain this information.
In this commit a custom `ParseIntError` type is crated that carries the
one from `core` as well as additional information. Its `Display`
implementation displays this additional information as a well-formed
English sentence to aid users with understanding the problem. A helper
function parses any integer type from common string types returning the
new `ParseIntError` type on error.
To clean up the error code a bit some new macros are added and used.
New modules are added to organize the types, functions and macros.
Closes#1113
Add a `LockTime` type to hold the nLockTime `u32` value. Use it in
`Transaction` for `lock_time` instead of a `u32`. Make it public so this
new type can be used by rust-miniscript and other downstream projects.
Add a `PackedLockTime` type that wraps a raw `u32` and derives `Ord`,
this type is for wrapping a consensus lock time value for nesting in
types that would like to derive `Ord`.
Integers within Script can have a maximum value of 2^31 (i.e., they are
signed) but we (miniscript) often uses unsigned ints, to facilitate
checking the unsigned type is the correct size to fit in a signed int
add a const `MAX_SCRIPTNUM_VALUE`.
For internal macros used only in this crate we do not need to use
`macro_use` and pollute the top level namespace now that we have edition
2018. We can add a `pub(crate) use` statement to each and then path
imports work for the macros like normal types.
Now we have edition 2018 we do not need to use `macro_use` or `extern
crate`; `pub use` works with macros.
Remove the extern crate statement and replace it with a pub use
statement. Requires fixing up various imports statements and also
requires importing `sha256t_hash_newtype` macro directly instead of
using a qualified path to it.

This is dr-orlovsky's [PR](https://github.com/rust-bitcoin/rust-bitcoin/pull/899) picked up at his permission in the discussion thread.
I went through the review comments and implemented everything except the perf optimisations. Also includes a patch at the front of the PR that adds a unit test that can be run to see the "before and after", not sure if we want it in, perhaps it should be removed before merge.

Previous implementations of Witness (and Vec<Vec<u8>>) serde serialization
didn't support human-readable representations. This resulted in long unreadable
JSON/YAML byte arrays, which were especially ugly when pretty-printed (a line
per each byte).

This also removes tests for JSON backward-compatible encoding. Human-readable
encoding will be changed in the next commit and this will break backward
compatibility, thus that part of the test is removed.
91ff2f628c Introduce SPDX license identifiers (Tobin C. Harding)
Pull request description:
When `rust-bitcoin` was started in 2014 the SPDX license list and short identifiers where not a thing. Now that we have short identifiers and they are gaining popularity in other projects we can consider using them.
- Add links to the SPDX website in the readme
- Shorten the author section to a single line
- Remove all the licence information in each file and replace it with an
SPDX ID (see https://spdx.dev/ids/#how)
Of note:
- If the author of a file is explicitly listed, maintain this information
- If the 'author' is listed as the generic 'Rust Bitcoin developers' just remove the attribution, this is implicit. This does loose the date info but that can be seen at any time from the git index using
`git log --follow --format=%ad --date default <FILE> | tail -1`
apoelstra, please confirm that I'm not treading on your toes here, especially, are you ok with the new 'written by' string format?

Last release, before we had access to `non_exhaustive` we added some fancy types to enable conditionally having a `bitcoinconsensus::Error`.
Now that we have bumped the MSRV and have already added `non_exhaustive` to the `Error` type in question, we can use a compiler attribute to conditionally include the `bitcoinconsensus` error.
Remove `Uninhabited` and its usage.

(*) - I'm benchmarking on a noisy laptop. Take this with a grain of salt. But I think
at least it doesn't make anything slower.
While doing all this manual labor that will probably generate conflicts,
I took a liberty of changing generic type names and variable names to
`r` and `R` (reader) and `w` and `W` for writer.

Pull request description:
Audit the whole codebase checking for any method that is of the form `from_foo` where foo is not an interesting identifier (like 'consensus' and 'standard'). Implement `TryFrom` for any such methods, deprecating the original.
Done as separate patches so any can be easily dropped if not liked.
