repository.c: move env-related setup code back to environment.c

Browse Source 
It does not make sense that generic repository code contains handling
of environment variables, which are specific for the main repository
only. Refactor repo_set_gitdir() function to take $GIT_DIR and
optionally _all_ other customizable paths. These optional paths can be
NULL and will be calculated according to the default directory layout.

Note that some dead functions are left behind to reduce diff
noise. They will be deleted in the next patch.
