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.

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`.

The Lightning network defines a type called 'chain hash' that is used to
uniquely represent the various Bitcoin networks as a 32 byte hash value.
Chain hash is now being used by the DLC folks, as such it is useful to
have it implemented in rust-bitcoin.
One method of calculating a chain hash is by hashing the genesis block
for the respective network.
Add a `ChainHash` type that can be used to get the unique identifier of
each of the 4 Bitcoin networks we support. Add a method that returns
the chain hash for a network using the double sha256 of the genesis
block. Do so using hard coded consts and add unit
tests (regression/sanity) that show these hard code byte arrays match
the hash of the data we return for the genesis block for the respective
network.
The chain hash for the main Bitcoin network can be verified from LN
docs (BOLT 0), add a link to this document.
Since commit `commit 275adc6c335a4326699cfbd444949e1725864ea1` on

No manual changes made. The result of the command above is just to fix
all the use statements (add `crate::`) and fix the fully qualified path
formats i.e., `::Foo` -> `crate::Foo`.
We do this all over the place in rust-lightning, and its probably
the most common thing to do with a `Witness` so I figured I'd
upstream the util method to do this. It also avoids an allocation
compared to the naive approach of `SerializedSignature.to_vec()`
with two pushes, which is nice.
4f1200d629 Added `amount::Display` - configurable formatting (Martin Habovstiak)
Pull request description:
This significatnly refactors the formatting code to make formatting more
configurable. The main addition is the `Display` type which is a
builder that can configure denomination or other things (possibly more
in the future).
Further, this makes all representations of numbers minimal by default,
so should be documented as a possibly-breaking change.
Because of the effort to support all other `fmt::Formatter` options this
required practically complete rewrite of `fmt_satoshi_in`. As a
byproduct I took the opportunity of removing one allocation from there.

7854bd7918 Fix `no_std` MSRV Fixes#690, #947 (mcroad)
Pull request description:
`rust-bitcoin` does not work with rust 1.29 under a `no_std` environment. This could be considered a bug. However, `no_std` support is a recent addition and this is likely not breaking anyone's builds.
A decision needs to be made, either `no_std` MSRV is the current stable version while keeping the `std` MSRV as 1.29, or it needs to be fixed.
This pr adds `no_std` to the 1.29 test suite.
This came as I try to get rust-bitcoin/rust-miniscript#277 working and got stuck on the issue of testing `no_std` under 1.29.

This creates a few primitive functions for handling iterators and uses
them to avoid repeated code. As a result not only is the code simpler
but also fixes a forgotten bound check. Thanks to a helper function
which always does bounds check correctly this can no longer be
forgotten.
This refactors `blockdata::script::Instructions` to use
`::core::slice::Iter<'a, u8>` instead of `&'a [u8]` to better express
the intention and to avoid some slicing mistakes. Similarly to a

In the future, TapTree may iterate over different node types, and that's why it does not have `iter()` function; using instead `script_leafs`. Thus, we should not have IntoIterator implementation as well
Previously used depth and script tuple missed information about the leaf version.
All three comprises already existing type `LeafInfo` which was made public in
previous commits.
