Similarly to the previous commit, introduce an option for hex_to_bytes
to allow us to specify the kind of hex to use: lowercase only or not.
For now, everything remains the same as before, but we will change
things in a future commit.

We currently allow both upper and lower case for all hex values in Git.
However, in a future commit, we'll want to change that to allow only
lowercase values in some cases. To prepare for that case, provide a
table to convert hex values using lowercase only and an enum to let us
choose which we want, wiring it up to the hexval function.
For now, keep things completely the same by specifying only the
variant that accepts both lowercase and uppercase to avoid changing
behavior.

In order to further reduce all-in-one headers, separate out functions in
hex.h that do not operate on object hashes into its own file, hex-ll.h,
and update the include directives in the .c files that need only such
functions accordingly.
