refs.c: optimize check_refname_component()
In a repository with many refs, check_refname_component can be a major
contributor to the runtime of some git commands. One such command is
git rev-parse HEAD
Timings for one particular repo, with about 60k refs, almost all
packed, are:
Old: 35 ms
New: 29 ms
Many other commands which read refs are also sped up.
