3333dbab24 Use new read_to_limit function (Tobin C. Harding)
f29da57ef6 io: Add functions to read to the end of a reader (Tobin C. Harding)
Pull request description:
Total re-write, now does:
- Add a method to the `io::Take` trait `read_to_end`
- Add a method to the `io::Read` trait `read_to_limit` (with default impl that calls through to `Take::read_to_end`)
- Use the new methods and remove `psbt::read_to_end`

The `std::io::Read` trait includes `read_to_end` but that method
provides a denial of service attack vector since an unbounded reader
will exhaust all system memory.
Add a method to our `Read` trait called `read_to_limit` that does the
same as `std::io::Read::read_to_end` but with memory exhaustion
protection.
Add a `read_to_end` method on our `Take` trait and call through to it
from the new method on our `Read` trait called `read_to_limit`.
Our decoding code reads bytes in very small chunks. Which is not
efficient when dealing with the OS where the cost of a context switch is
significant. People could already buffer the data but it's easy to
forget it by accident.
This change requires the new `io::BufRead` trait instead of `io::Read`
in all bounds.
Code such as `Transaction::consensus_decode(&mut File::open(foo))` will
break after this is applied, uncovering the inefficiency.
This was originally Kix's work, done before we had the `io` crate.
Changes to `bitcoin` were originally his, any new mistakes are my own.
Changes to `io` are mine.

The effective_value method is useful for coin selection algorithms. By
providing this effective value method, the effective value of each
output can be known during the coin selection process.

Fix: #575
Add a `BufRead` trait for types that perform buffered reading.
Implement it for:
- `Take`
- `Cursor`
- `std::io::BufRead` readers
- (in no-std builds) for slice of u8s

518f0970c9 Implement ArbitaryOrd for absolute::LockTime (Tobin C. Harding)
Pull request description:
At times we would like to provide types that do not implement `PartialOrd` and `Ord` because it does not make sense. I.e we do not want users writing `a < b`. This could range from kind-of-iffy to down-right-buggy (like comparing absolute locktimes).
However this decision effects downstream users who may not care about what the ordering means they just need to use it for some other reason e.g., to use as part of a key for a `BTreeMap` (as we do in `miniscript` requiring the `AbsLockTime` type).
A solution to this problem is to provide a wrapper data type that adds `PartialOrd` and `Ord` implementations. I wrote the `ordered` crate is for this very purpose.

271b45299f Improve Signature field names (Tobin C. Harding)
Pull request description:
Applies to both `ecdsa::Signature` and `taproot::Signature`.
Re-name the `Signature` fields with more descriptive names. The names used were decided upon in the issue discussion.
Impove rustdocs while we are at it.
Note, the change to `sign-tx-segwit-v0` is refactor only, the diff does not show it but we have a local variable already called `sighash_type` that is equal to `EcdsaSighashType::All`.

Fix: #2139
Our `Amount` type uses an internal `u64` and we maintain no invariants
on the inner value. Therefore we should be able to parse `u64::MAX`.
Fix the parsing code by removing the explicit, incorrect check and fix
unit tests to mirror this behaviour.

e762c53725 fix nightly clippy issues (Andrew Poelstra)
Pull request description:
I don't mind making these PRs, but I think we should start pinning our nightlies, and using a script to update the pin every week (or day, or whatever). When our CI breaks due to tooling changes, it means that our release branches will have permanently broken CI jobs, which I'd like to avoid in the future.
If the automatic pin update failed, we'd close it and manually create one that fixed the nw issues.

a8d50a5541 Remove Push enum (Tobin C. Harding)
Pull request description:
The `Push` enum is only ever used to get access to one of its variants. Since it is a private type we can remove it entirely and just return `PushBytes` from the `last_pushdata` function.

089ce8f0fb Deprecate `Script::is_provably_unspendable` (Martin Habovstiak)

This method is not really that useful because it checked an arbitrary condition. There already exists `OP_RETURN` semantics and the method didn't cover all possible ways the script may be invalid.
