brian m. carlson fa632be563 hex: add functionality for lowercase-only hex ...

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.
