Merge rust-bitcoin/rust-bitcoin#798: Audit conversion methods

Pull request description:

  Rust has naming conventions surrounding conversion functions

  We have a handful of methods that are not following convention. This PR is done as three patches, separated by incorrect function name (`into_` or `as_`) and by whether or not the original method needs deprecating. Can be squashed if folks prefer.

  From the docs: https://rust-lang.github.io/api-guidelines/naming.html

  <h2><a class="header" href="https://rust-lang.github.io/api-guidelines/naming.html#ad-hoc-conversions-follow-as_-to_-into_-conventions-c-conv" id="ad-hoc-conversions-follow-as_-to_-into_-conventions-c-conv">Ad-hoc conversions follow <code>as_</code>, <code>to_</code>, <code>into_</code> conventions (C-CONV)</a></h2>
  <p>Conversions should be provided as methods, with names prefixed as follows:</p>

  Prefix | Cost | Ownership
  -- | -- | --
  as_ | Free | borrowed -> borrowed
  to_ | Expensive | borrowed -> borrowed
  | | | borrowed -> owned (non-Copy types)
  | | | owned -> owned (Copy types)
  into_ | Variable | owned -> owned (non-Copy types)

  EDIT: I did actually audit all uses of `to_` when I first did this, I did this by grepping for `fn to_` and checking the output against the table.

Merge rust-bitcoin/rust-bitcoin#1023: Add `consensus_decode_from_finite_reader` optimization
082e185711 Add `consensus_decode_from_finite_reader` optimization (Dawid Ciężarkiewicz)

Pull request description:

  As things are right now, memory exhaustion protection in `Decodable`
  is based on checking input-decoded lengths against arbitrary limits,
  and ad-hoc wrapping collection deserialization in `Take`.

  The problem with that are two-fold:

  * Potential consensus bugs due to incorrect limits.
  * Performance degradation when decoding nested structured,
    due to recursive `Take<Take<..>>` readers.

  This change introduces a systematic approach to the problem.

  A concept of a "size-limited-reader" is introduced to rely on
  the input data to finish at enforced limit and fail deserialization.

  Memory exhaustion protection is now achived by capping allocations
  to reasonable values, yet allowing the underlying collections
  to grow to accomodate rare yet legitmately oversized data (with tiny
  performance cost), and reliance on input data size limit.

  A set of simple rules allow avoiding recursive `Take` wrappers.

  Fix #997

Tobin C. Harding 99f565f932 Add non_exhaustive to all error enums
Adding an error variant to a public enum is an API breaking change, this
means making what could be small refactorings or improvements harder. If
we use `non_exhaustive` for error types then we mitigate this cost.
There is a tradeoff however, downstream users who explicitly match on
our public error types must include a wildcard pattern.

Tobin C. Harding a6efe982bd Use write_all to write whole buffer
A better way to write a byte string is to use write all so that
`ErrorKind::Interupted` is not returned.

Use `write_all` to write the non-sense (error indication) string to the
writer when we hit the SIGHASH_SINGLE bug.

Tobin Harding 5fbb211085 Use fn name to_ instead of as_
Rust convention is to use `to_` for conversion methods that convert from
an owned type to an owned `Copy` type. `as_` is for borrowed to borrowed
types.

owned `Copy` types to use `to_`.

Tobin C. Harding 6874ce91e2 Remove as_inner
`self` and the referenced type returned by `as_inner` are both `Copy`
types. There is no need to provide an reference getter method to a
`Copy` type since implementing `Copy` implies that copying is cheap.

Tobin C. Harding 57dd6739c3 Do not print error when displaying for std builds
We implement `source` for all our error types. This means that we should
not display the source error explicitly because users can call `source`
to get the source error.

However, `std::Error::source()` is only available for "std" builds, so
that we do not loose the error source information in "no-std" builds add
a macro that conditionally adds the source onto the error message.

Martin Habovstiak 2e7effc604 Feature `use-serde` renamed to `serde`
Features activating external crates are supposed to have same name as
those crates. However we depend on same feature in other crates so we
need a separate feature. After MSRV bump it is possible to rename the
crates and features so we can now fix this inconsistency.

Sadly, derive can't see that the crate was renamed so all derives must
be told to use the other one.

Merge rust-bitcoin/rust-bitcoin#968: Refactor address byte swapping
07c75304d2 Refactor address byte swapping (Tobin C. Harding)

Pull request description:

  Refactor address byte swapping

  When encoding a `network::Address` two of the fields are encoded
  big-endian instead of little-endian as is done by `consensus_encode`. In
  order to achieve this we have a helper function `addr_to_be` that swaps
  the bytes. This function is miss-named because it is not converting to a
  specific endian-ness (which implies different behaviour on machines with
  different endian-ness) but is reversing the byte order irrespective of
  the underlying architecture.

  - Remove function `addr_to_be`
  - Inline the endian-ness code when encoding an address
  - Remove TODO and use `to_be_bytes` when encoding port
  - Add a function for reading big-endian bytes `read_be_address`
  - Use `read_be_address` when decoding `Address` and `Addrv2`

  Refactor only, no logic changes. Code path is already covered by
  unit tests.

Merge rust-bitcoin/rust-bitcoin#980: Remove sha256t_hash_newtype macro
58f94bee9b Remove sha256t_hash_newtype macro (Tobin C. Harding)

Pull request description:

  Since commit `commit 275adc6c335a4326699cfbd444949e1725864ea1` on `bitcoin_hashes` we have the identical implementation of the macro `sha256t1_hash_newtype` in this crate and in `bitcoin_hashes`.

  Remove the `sha256t_hash_newtype` macro from this crate in favour of the one in `bitcoin_hashes`.

Merge rust-bitcoin/rust-bitcoin#960: Trival docs fixes
90b4f1cde8 Clear TapTreeIter clippy warning (Tobin C. Harding)
e6084a1af8 Improve documentation around EcdsaSig (Tobin Harding)

Pull request description:

  Do a couple of trivial docs fixes, done during other work.

  - Patch 1 improves docs on the `EcdsaSig` struct
  - Patch 2 clears a clippy warning during docs build - no sure if the solution is the best available though

Merge rust-bitcoin/rust-bitcoin#978: Make Address::get_payload_bytes public
7ca30b6aa8 Move Address::payload_as_bytes to Payload::as_bytes (Fredrik Meringdal)
525ea00e0f Make Address::get_payload_bytes public (Fredrik Meringdal)

Pull request description:

  Hi, thanks for the amazing work on this crate.

  I am trying to upgrade from v0.27 to v0.28, but unable to do so because the `Address::get_payload_bytes` was made private. My use-case is that I have a script hash address and an `Address` and need to compare the two, and in order to do so I need access to the payload bytes of `Address`.
  I hope you will consider making this function public again 🙏
