The `empty` constructor is mis-named for the following reasons:
- Non-uniform with `ScriptBuf::new`
- Non-standard with respect to stdlib which uses `Path::new` and
`PathBuf::new` (on which we based the `Scritp`/`ScriptBuf`)
Rename the function to `new`, put it at the top of the impl block while
we are at it.
fc167097aa Added examples for sighash computations (Alec Matusis)
Pull request description:
So far computed sighashes and verified signatures for:
- P2WPKH
- P2MS 2of3
- P2SH 2of2 multisig
- P2SH 2of3 multisig
- P2WSH 2of2 multisig.
TODOs:
- Add P2TR script-path multisig and key-path examples
- Are there mutisig transactions where flags are different for diff signatures within an input?
- Maybe switch to segwit_signature_hash()?
- Consider also verifying script hash if we go for full P2(W)SH transactions verifications?

Expose signature verification functionality for ECDSA signatures on the
`PublicKey` type.
We should have an identical function on `XOnlyPublicKey` but this will
have to be done in `secp2561`.
7cdc90565f Mutate mul_u64 with mutagen (Tobin C. Harding)
Pull request description:
Add the `mutate` attribute to mutate `mul_u64`. Add non-doc comments listing the two false positives. These are identical but we list them twice so when devs grep for `mutagen false pos` the same number of lines for each function is displayed as is displayed by the `mutagen` run. This coding false positives thing is also introduced in PR #1655.

Added a `const` associated function `from_int_btc()` for Amount. `panic()` in const context is only available after 1.57+ so a work around is provided.

638445f8a9 Feature: Add opcodes::All::decode_pushnum and Script::count_sigops (junderw)
Pull request description:
Planning to also add methods for the various parts of Transaction etc. to eventually allow for easier sigops calculation.
Bare multisig is making a comeback, which is causing a large amount of transactions' effective vSizes (for fee calculation) to be dependent on the sigop count.
This is a first step at making those transactions easier to estimate fees for / template blocks for etc.

This implements basic facilities to conditionally carry string inputs in
parse errors. This includes:
* `InputString` type that may carry the input and format it
* `parse_error_type!` macro creating a special type for parse errors
* `impl_parse` implementing parsing for various types as well as its
`serde`-supporting alternative
The `as_script_map` is a getter not a conversion function (to/into/as),
as such it should not include the prefix `as_`.
Deprecate `as_script_map` in favour of `script_map`.
This error type is only used in the `from_slice` function. Use prefix
`Sig` because `taproot::FromSliceError` does not fully express how the
error came about.
Use specific identifier for the error, this aids usage but also prevents
us later adding "random" other variants into this error and using it in
other functions.
06afd52a12 Improve hashes::Error (Tobin C. Harding)
Pull request description:
We are trying to make error types stable on the way to v1.0
The current `hashes::Error` is a "general" enum error type with a single variant, better to use a struct and make the error usecase specific.
Improve the `hashes::Error` by doing:
- Make it a struct
- Rename to `FromSliceError`
- Move it to the crate root (remove `error` module)
Includes usage in `bitcoin`.

Add a `ValidationError` to the `block` module and remove the two
variants out of `crate::Error`.
This error is only used by the `validate_pow` function, a specific error
better serves our purposes.

013dffa65d tests: Use script hash methods (Tobin C. Harding)
Pull request description:
The `ScriptBuf` type can be serialized using it's `to_bytes` function. Do not use the `psbt::Serialize` trait to do so in test code.
No logic changes, since the impl of `psbt::Serialize` for `ScriptBuf` just calls `to_bytes`.
