strbuf_branchname(): a wrapper for branch name shorthands

The function takes a user-supplied string that is supposed to be a branch
name, and puts it in a strbuf after expanding possible shorthand notation.

A handful of open coded sequence to do this in the existing code have been
changed to use this helper function.
