Merge rust-bitcoin/rust-bitcoin#2336: units: Enable parsing Amount from `u64::MAX`

1d536ac8b2 units: Enable parsing Amount from u64::MAX (Tobin C. Harding)

Pull request description:

  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.

  Fix: #2297

units: Assert roundtrip SignedAmount/str overflows
Add a unit test to prove that attempting to roundtrip a `SignedAmount`
greater than `MAX` through a string fails.

units: Test that SignedAmount float conversion overflows
We should not be able to roundtrip a `SignedAmount` value greater than
`MAX`, add a test to prove so.

While we are at it document the assertion above that proves we can parse
a float representing an `Amount` greater than `SignedAmount::MAX`.

Unit test has a duplicate assertion, remove it.

Martin Habovstiak 22747149a9 Add convenience constants to `Denomination`
`Denomination::Bitcoin` and `Denomination::Satoshi` are often used,
especially in test code so this change adds `BTC` and `SAT` - short,
readable constants. Notably this doesn't add the other constants as that
would lead to either unidiomatic names or confusing casing (MSAT meaning
millisat not megasat) and they are not used that much anyway.

Pull request description:

  A few cleanups to how we use the `io` crate, this is reasonably trivial but commit `a6c7e696 Remove qualifying path from Read and Write` is big, I have however gone to some effort to make sure it is easy to flick through the diff.

  Done in preparation for another go at the `BufRead` stuff.

Allow `SignedAmount` parse values equal to i64::MIN
Previously, parsing such textual value returned 'too big' error. This
change fixes it and adds relevant tests.

Import fmt::Write using underscore
When we use the `fmt::Write` trait it is just to call its methods, we
can therefore, without any change to the logic, use `as _` when
importing the trait. This prevents naming conflicts.

Done in preparation for importing the `io::Write` trait.

Use InputString instead of String
Done so that we can correctly support builds without an allocator.

Add two new error types that wrap `InputString`.

Add ParseDenominationError
We have two variants in the `ParseAmountError` that both come from
parsing a denomination, these should be a separate error.

Add bitcoin-units crate
Add a new crate `bitcoin-units`, move the `amount` module over to it and
re-export all types from `bitcoin::amount` so this as not a breaking
change.
