Pull request description:
One final push crew, 16 patches, only a few are big.
All non-trivial formatting is done in separate patches so the changes can be verified mechanically.
With this applied the whole `rust-bitcoin` crate will be formatted.
Big thanks to everyone for putting up with the ongoing formatting PRs, no-one likes doing these but hopefully this an improvement to the project - especially in helping us get more contributors to the project.

Pull request description:
I was looking to maintain compatibility easily with core tests, and many of the tests use [cent](40e1c4d402/src/test/util/setup_common.h (L74)) denominations. It would be nice to be able to use cent as a denomination in rust-bitcoin as well.

The `hashes` module contains a bunch of arrays, mostly formatted with 8
hex bytes on a line; add `rustfmt::skip` to keep the formatting of
arrays as is.
Remove the exclude for the `hashes` crate. Do not run the formatter,
that will be done as a separate patch to aid review.
Add `rustfmt::skip` attribute in a couple of places and then remove the
exclude for the `blockdata` module. Do not run the formatter, that will
be done as a separate patch to aid review.
Currently we have a code comment that is supposed to assist devs in
maintaining the `network::constants::Network` type by failing to build
if a new variant is added. This plays havoc with the formatter because
the comment is hanging at the bottom of a match block and the formatting
thinks its for the proceeding line of code.
Instead of using a code comment add a panic so the unit test fails if a
new variant is added to `network::constants::Network`.
In preparation for running the formatter introduce a couple of local
variables to reduce the line length and inhibit function call from being
split over multiple lines.
Refactor only, no logic changes.

00b46d6d9d Indent functions (Martin Habovstiak)
d56d202aeb Support weight prediction in `const` context (Martin Habovstiak)
Pull request description:
**Notes for reviewers:**
This is something that I want to use in my code and hopefully reasonably easy to review, so if this can get into 0.30 that'd be really nice. No hard feelings if it doesn't.
I tried to put extra effort into making review easier by:
* intentionally "mis-formatting" the first commit so diff is smaller and easy to understand - see individual commits.
* copying patterns from non-const fn to const fn so it's obviously correct (includes same variable names)
* not bothering with the array trick in `VarInt::len` and simply accepting the limitation of Rust 1.46+ (I use 1.48 BTW).
**Description**
Some smart contracts or simplified wallets statically know the sizes of
transactions or inputs. The possible approaches to handling them so far
were re-computing the values (and hoping the optimizer will const fold
them) or using a simple constant which may be harder to understand and
get right. It's much nicer to just use a `const` but our code didn't
support it until now.
This change adds methods that can compute the prediction in `const`
context for Rust versions >= 1.46.0 which allow use of loops (and
conditions but those could be workaround anyway).
As a side effect of this, the change also adds `const` to `VarInt::len`
in Rust 1.46+. While this one could be made unconditional using array
trick it's probably not worth it because of the planned MSRV bump.

2961c0c589 Exclude usage of atomic types if not supported for the target (Salvatore Ingala)
Pull request description:
Hi! I'm still a beginner with both Rust and cross-compilation, so please take the rest with a few grains of salt!
I'm setting up a project targeting `riscv32i-unknown-none-elf`, which seems not to support atomic types. Even with `--no-default-features` and `no-std`, I would get this error:
```

This PR gates the usage of `Arc` so that it's only enabled with the `std` feature.

a6188a90c0 Improve QR code formatting documentation (Martin Habovstiak)
Pull request description:
It wasn't obvious that displaying address with alternate formatting upper cases bech32 addresses.
This change adds information about this and also a note about the compatibility of various wallets.
BTW why do we prefix upper case `BITCOIN` only in case of bech32? Proper BIP21 should support it for all addresses. (And yest, it still does save space.)

2158f88f1d Add a method to `pow::Target` for returning difficulty as an f64. (junderw)
Pull request description:
Closes#1703
This adds a conversion function to U256 to get an f64. We use the method shown in the following blog post.
https://blog.m-ou.se/floats/
Target::MAX was converted to a f64 and set as a const that is verified in a unit test.
The code is rather confusing, so I took a crack at explaining it in my comments as well. Please let me know if you want it cleaned up some more.
