Redesign `hex::BufEncoder` to accept owned arrays

Not being able to create an owned `BufEncoder` prevented returning it
from functions which need to allocate the buffer on stack. Such is the
case in WIP serde via consensus serialzation.

This change refactors `OutBytes` to be unsized, adds an `AsOutBytes`
trait and uses that one instead of `Into` to perform the conversion.

Implement basic support for fast hex encoding

There's a `hex` module in `bitcoin_hashes` which is a bit out of place
and not very fast - it passes each *digit* through dynamic dispatch not
only adding overhead but also not allowing `String` to make better
allocations.

This change adds basic support for hex encoding using a stack-allocated
buffer which minimizes the overhead of dynamic dispatch. It also
provides a new `DisplayHex` trait designed to replace `ToHex` found in
`bitcoin_hashes`.

Introduce bitcoin-internals crate

Add a new crate `bitcoin-internals` to be used for internal code needed
by multiple soon-to-be-created crates.

Add the `write_err` macro to `bitcoin-internals`, nothing else.

This patch uses a `path` dependency which means `rust-bitcoin` cannot be
released in its current state, will need to be changed once we release
the `bitcoin-internals` crate on `crates.io`.
