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.

"schnorr" is a dirty word; the current `schnorr` module defines a
`Signature` that includes a sighash type, this sighash type is a bitcoin
specific construct related to taproot. Therefore the `Signature` is
better named `taproot::Signature`. Note also that the usage of `schnorr`
in `secp256k1` is probably justified because the
`secp256::schnorr::Signature` is just doing the crypto.
While we are at it, update docs and error messages to use "taproot"
instead of "schnorr". Also change function names and identifiers that
use "schnorr".
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.
There is never any use for the `sighash` module unless one is signing,
which requires the `crypto` module. The `sighash` module should
therefore live in the `crypto` module. This is not an API breaking
change because we reexport it at the crate root.
`Signature` only supported serialization into `Vec` which required a
heap allocation as well as prevented statically proving maximum length.
Adding a specialized type that holds a byte array and size solves this.
The solution is very similar to `secp256k1::ecdsa::SerializedSignature`.
The difference is that serialized signature in this crate contains
sighash bytes flag while in `secp256k1` it doesn't.
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.
a121e19e94 hashes: Implement AsRef for fixed size arrays (Tobin C. Harding)
Pull request description:
Implement `AsRef<[u8; X]>` for hash types including wrapped hash types. Doing so means at times the compiler can no longer infer the type because we have `AsRef<[u8]` implemented also but we can use `into_inner` and `as_inner` to get the inner array if needed.
Fix: #1462
## Note
This touches code that will likely be changed by #1577 and when we do #1491 but I believe its a step forward.

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.

In some cases people construct the transaction with a dummy fee output

over `script_pubkey` lengths is useful in such cases.

There are many more changes in the pipeline for all this read/write "script int" stuff. This PR was done ages ago and I believe it stall adds value.
I re-did the whole PR manually because of the recent `script` module changes. I hope no one else has to do that - if you do please feel free to holla and I'll "rebase" your PR for you.

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).
