khash: implement begin/end via functions instead of macros

Right now, the `git_*map_begin()` and `git_*map_end()` helpers are
implemented via macros which simply redirect to `kh_begin` and `kh_end`.
As these macros refer to members of the map structures, they make it
impossible to move the khash include into the implementation files.

Implement these helpers as real functions instead to further decouple
the headers from implementations.
