The BIP-158 finalize code was serializing value to `Vec` only to
serialize it to writer right away. Thus the intermediary `Vec` was not
needed.
Even more, the code used `write` which, while correct in case of `Vec`,
could trigger code analysis tools or reviewers.
After MSRV bump `try_from` usually refers to `TryFrom` method but
`CommandString` used inherent one making it confusing and non-idiomatic.
This implements `FromStr` and `TryFrom<{stringly type}>` for
`CommandString` and deprecates the inherent method in favor of those.
To keep the code using `&'static str` efficient it provides
`try_from_static` inherent method that only converts from
`&'static str`.

071a1c02b7 Implement string parsing for `Sequence` (Martin Habovstiak)
c39bc3909d Extend `ParseIntError` to carry more context (Martin Habovstiak)
Pull request description:
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.

`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`.

0ed78e543b Add lock time types (Tobin C. Harding)
1390ee12ec Add a max scriptnum constant (Tobin C. Harding)
Pull request description:
Implement a `LockTime` type that adds support for lock time values based on nLockTime and OP_CHECKLOCKTIMEVERIFY.
For example usage in `rust-miniscript` please see https://github.com/rust-bitcoin/rust-miniscript/pull/408.
### Notes:
I probably should have opened a new PR, this is a total re-write and very different from what is being discussed below, sorry, my bad.
This is just half of the 'timelock' story, its the easier half. The reason I switched terminology from timelock to locktime is that we have to compare two u32s so it does not make sense to call them _both_ timelocks.
If I have missed, or apparently ignored, anything you said reviewers please accept my apology in advance, it was not intentional. The thread of discussion is long and this topic is complex. Please do restate your views liberally :)
Here is a useful blog post I used while touching up on timelock specifics: https://medium.com/summa-technology/bitcoins-time-locks-27e0c362d7a1. It links to all the relevant bips too.

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`.

This is a rebase of #249 by stevenroose (see https://github.com/rust-bitcoin/rust-bitcoin/pull/249#issuecomment-1170562141) with a milestone for 29.0. I've added deserialization and serialization tests for the network messages and fixed an off-by-one bug in the deserialization of the differentially encoded varints in the `getblocktxn` message (see https://github.com/rust-bitcoin/rust-bitcoin/pull/249#discussion_r914989521).
Closes#249.

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. Notable exceptions are `alloc` and
`test`. Also leave the serde rename because touching it opens a can of
worms.
Recently we removed the "unstable" feature, I missed the duplicate
`extern crate test` when doing so :(
Since we no longer have the "unstable" feature this line of code is
never compiled in.
Remove the unused ``extern crate test`, we have the correct line further
up the file `#[cfg(bench)] extern crate test;`.
Now we have edition 2018 we do not need to use `macro_use` or `extern

using a qualified path to it.
ded1a32a59 Add cargo crev reminder to readme (Tobin C. Harding)
Pull request description:
As suggested by the `cargo-crev` project; add a comment to the readme reminding people to use `cargo-crev` to check their dependencies.
### Notes
Today I explored `cargo-crev`, it was new to me before today. I completed proofs for `bech32`, `rust-bitcoinconsenus`, `bitcoin_hashes`, `rust-secp256k1`, and `rust-bitcoin`. I published the proofs to https://github.com/tcharding/crev-proofs.
If I'm understanding correctly proofs are only useful if the author is connected to a web of trust. So far I only found @dpc within the active rust-bitcoin devs with a `crev-proofs` repo (that includes an ID). Since he wrote `cargo-crev` its not surprising he has one :) Two other devs have `crev-proofs` repos but they are both incomplete (no ID) so I was unable to climb onto their web, so to speak. I am not a particularly well know dev so I imagine it would be more useful if some of you more well know fellas publish proofs as well.
If we can get a web of trust between all the regular hackers here then we can start doing reviews/proofs of our dependencies and publishing them.

Pull request description:
Looks like we are getting to a place that rustfmt _might_ be able to be used. In an effort to introduce `rustfmt` without requiring devs to do excessively mundane reviews introduce `rustfmt` in a non-invasive manner. What this means is
- Add a fully fleshed out `rustfmt` config file that explicitly ignores all the source files
- Enable sections of code one by one so review is easier (including preparatory patches before doing each section).
This PR currently does `examples` and all the source files at the root level of the crate (i.e. excludes all directories in `src/`). The other directories can then be done one at a time.

We create and update a PSBT using the watch-only wallet then pass the PSBT to the cold-storage wallet to sign.
Partially resolves#892 (more done in #935).
## Note
This PR includes a sub-module in `examples/psbt.rs` that implements ECDSA signing. This will hopefully eventually be merged into the main crate by way of https://github.com/rust-bitcoin/rust-bitcoin/pull/957. We have three PRs that add examples/tests of PSBTs that need to do signing, in order to help us design a good AP in #957 I think it would be beneficial to complete and merge these three PRs.
1. This PR (PSBT ECDSA example)
2. PBST ECDSA integration test: https://github.com/rust-bitcoin/rust-bitcoin/pull/935
3. PSBT taproot example: https://github.com/rust-bitcoin/rust-bitcoin/pull/999
Note to self, this will need a change to `test.sh` if #1079 merges.
