f31fb08651 Remove default impl from transaction version (Tobin C. Harding)
Pull request description:
There is no logical default for the transaction version number, there is only pre-bip68 (v1) and post-bip68 (v2). Uses should specify the version they want not rely on us making the choice.
(I originally added this impl to support testing, this was in hindsight the wrong thing to do, props to Sanket for noticing.)

Recently we introduced a bug in the weight/size code, while
investigating I found that our `Transaction`/`Block` weight/size APIs
were in a total mess because:
- The docs were stale
- The concept of weight (weight units) and size (bytes) were mixed up
I audited all the API functions, read some bips (141, 144) and re-wrote
the API with the following goals:
- Use terminology from the bips
- Use abstractions that mirror the bips where possible
The `Witness::push_bitcoin_signature` method is old and a bit stale.
Bitcoin has taproot signatures now so the name is stale, also we have
the `crate::ecdsa::Signature` type that holds the secp sig and the hash
type so we can use that instead of having two separate parameters.
Add a new, up to date, `Witness::push_ecdsa_signature` function and
deprecate the `push_bitcoin_signature` one.
There is no logical default for the transaction version number, there is
only pre-bip68 (v1) and post-bip68 (v2). Uses should specify the version
they want not rely on us making the choice.
(I originally added this impl to support testing, this was in hindsight
the wrong thing to do, props to Sanket for noticing.)
One of our stated aims is to make it possible to learn bitcoin by using
our library. To help with this aim add to private consts for the segwit
transaction marker and flag serialization fields.
158ba26a8a Feature: Count sigops for Transaction (junderw)
Pull request description:
I copied over the sigop counting logic from Bitcoin Core, but I made a few adjustments.
1. I removed 2 consensus flags that checked for P2SH and SegWit activation. This code assumes both are activated. If we were to include that, what would be a good way to go about it? (ie. If I run this method on a transaction from the 1000th block and it just so happened to have a P2SH-like input, Bitcoin Core wouldn't accidentally count those sigops because the consensus flag will stop them from running the P2SH logic. Same goes for SegWit)
3. Since there's no guarantee that we have an index from which we can get the prevout scripts, I made it into a generic closure that looks up the prevout script for us. If the caller doesn't provide it, We can only count sigops directly in the scriptSig and scriptPubkey (no P2SH or SegWit).
## TODO
- [x] Write tests for transaction sigop counting
~~Edit: The test changes are just to get the 1.48 tests passing. I'll remove them and replace them with whatever solution that is agreed upon in another PR etc.~~
Edit 2: This is the code I used as a guide:
8105bce5b3/src/consensus/tx_verify.cpp (L147-L166)
Edit 3: I found a subtle bug in the implementation of `count_sigops` (https://github.com/rust-bitcoin/rust-bitcoin/pull/2073#issuecomment-1722403687)

95b7a95fc2 test: correct psbt used for regression test (Subhradeep Chakraborty)
Pull request description:
The `unknown` key used in the `Psbt` (in `serde_regression_psbt` test) is not really unknown. Also the `preimages` in the `Input` don't seem to be valid. Though they don't affect the tests because of the `serde::serialize`, the `Psbt` itself is invalid and hence this PR.

BIP-68 activated a fair while ago (circa 2019) and since then only
transaction versions 1 and 2 have been considered standard.
Currently in our `Transaction` struct we use an `i32`, this means users
can construct a non-standard transaction if they do not first look up
what the value should be. We can help folk out here by abstracting over
the version number.
Since the version number only governs standardness elect to make the
inner `i32` public (ie., not an invariant). The aim of the type is to
make life easy not restrict what versions are used.
Add transaction::Version data type that simply provides two consts `ONE`
and `TWO`.
Add a `Default` impl on `Version` that returns `Version::TWO`.
In tests that used version 0, instead use `Version::default` because the
test obviously does not care.

acbf23aaa5 Add `is_multisig` helper to Script type (Clark Moody)
Pull request description:
A new `is_multisig` helper method to classify bare multisig output scripts.
The form of a valid multisig script is:
- Pushnum `M`
- <N> pubkeys
- Pushnum `N`
- `OP_CHECKMULTISIG`
`N` must equal the number of pushed pubkeys, and `M` must be less than or equal to `N`.
I've tested this against the RPC output of Core at the block level, checking that the total number of multisig outputs matches.
```
Block 350338, 89 multisig
Block 350340, 29 multisig
Block 350341, 4 multisig
Block 350343, 579 multisig
Block 350344, 48 multisig

026a55809e Fix: Script::count_sigops parsing should not return a Result (junderw)
Pull request description:
When implementing some tests for the Transaction PR, I noticed that there were coinbase transactions that would pass Bitcoin Core parsing and fail my code.
It turns out that the Script parsing for sigops calls `break` to exit the loop and returns the current n value whenever there is an EarlyEndOfScript error.

These docs do not add that much value, we do not typically bother
documenting `From` and `TryFrom` implementations because they are super
well known and its obvious from the function signature what is going on.
The `address::Error` is module level general, we can make the code
easier to maintain and easier to stabalize by splitting the parse error
out of the general error.
Create a `ParseError` that is returned by `FromStr for Address`. Remove
the now unused variants from the general `address::Error`.
In an effort to reduce the number of lines of code import the error
variants locally within the `Display` impl on `Error`.
Refactor only, no logic changes.
Split the error code out of `address/mod.rs` and into
`address/error.rs`. Code move only, no changes other than to
imports/exports etc. to make it build.

4222e4d817 Add one-ack carve outside (Tobin C. Harding)
Pull request description:
In an effort to reduce review burden add so strict rules defining 3 times where we think it is acceptable for code to be merged with a single ACK. Feels a bit like we only just added the refactor carve-out and now we are adding more carve-outs, so whats next? We should take these rules seriously, if we are to be taken seriously.
```
We reserve the right to merge PRs with a single ACK [0], at any time, if they match
any of the following conditions:
1. PR only touches CI i.e, only changes any of the `test.sh` scripts and/or
stuff in `.github/workflows`.
2. Non-content changing documentation fixes i.e., grammar/typos, spelling, full
stops, capital letters. Any change with more substance must still get two
ACKs.
3. Code moves that do not change the API i.e., moving error types to a submodule
and re-exporting them from the original module. Must not include any code
changes except to import paths.
[0] - Obviously author and ACK'er must not be the same person.
