Currently the derived implementation of `Debug` for `ScriptBuf` prints
the inner vector of u8s as integers, this is ugly and hard to read. The
`Script` implementation of `Debug` prints the script opcodes and data as
hex, we can just delegate to it.
With this applied we get debug output of form:
Script(OP_DUP OP_HASH160 OP_PUSHBYTES_20 \

Recently we introduced some mutation testing to the `pow` module but
testing is never done - add more `mutate` attributes and add unit tests
to ensure all mutants are killed.
Of note, the `from_compact` and `to_compact_lossy` functions are not
done, doing so results in a bunch of surviving mutants.
Parsing addresses from strings required a subsequent validation of
network of the parsed address. However, this validation was not
enforced by compiler, one had to remember to perform it.
This change adds a marker type to `Address` that will assist the
compiler in enforcing this validation.
We use `internals::hex::display::DisplayHex` in many places, we can
improve ergonomics of the `internals` crate by re-exporting it from the
`prelude` module.

089a1e452d Replace `Vec::from_hex` with `hex!` (Martin Habovstiak)
Pull request description:
This makes the code less noisy and is a preparation for changing it to `const`-based literal. Because of the preparation, places that used variables to store the hex string were changed to constants.
There are still some instances of `Vec::from_hex` left - where they won't be changeable to `const` and where `hex!` is unavailable (integration tests). These may be dealt with later.
See also #1189
Note that while the change appears big it's nearly entirely mechanical, so should be pretty easy to review. (But I don't feel it's `trivial`.)

The additional `use` items were added to improve the style of
documentation. Because they were only used for doc they were `cfg`ed.
But because this is independent from being built by `docs.rs` the `cfg`
should've been `doc` not `docsrs`.
IOW `docsrs` means roughly `all(doc, nightly)` and the added items are
unrelated to `nightly`.

Add `#[inline]` to all public functions/methods excluding error types
and `Display` impls. Error paths do not need to be fast and presumably
`Display` is called on code paths that do IO so this also does not need
to be fast.

the current implementation due to overflow.
Re-write the `mul_u64` method.

a7f3458c27 Fix bug in `ScriptBuf::extend` for short iterators (Martin Habovstiak)
Pull request description:
`ScriptBuf::extend` contained an optimization for short scripts that was
supposed to preallocate the buffer and then fill it. By mistake it
attempted to fill it from already-exhausted iterator instead of the
temporary array it drained the items into. This obviously produced
garbage (empty) values.
This was not caught by tests because the optimization is only active for
scripts with known maximum length and the test used `Instructions` which
doesn't know the maximum length.

With this applied test can be run as usual with a stable toolchain. To run mutagen we use `RUSTFLAGS='--cfg=do_mutate' cargo +nightly mutagen` (doing so runs 29 mutants).

that depend on this feature.

This is useful when one already has bytes allocated in a vec that can be
reused.
The change also documents that the mirror method `into_bytes()` doesn't
allocate.
