Subject: commit: make 'commit_graft_pos' non-static

In the next patch, some functions will be moved from 'commit.c' to have
prototypes in a new 'shallow.h' and their implementations in
'shallow.c'.

Three functions in 'commit.c' use 'commit_graft_pos()' (they are
'register_commit_graft()', 'lookup_commit_graft()', and
'unregister_shallow()'). The first two of these will stay in 'commit.c',
but the latter will move to 'shallow.c', and thus needs
'commit_graft_pos' to be non-static.

Prepare for that by making 'commit_graft_pos' non-static so that it can
be called from both 'commit.c' and 'shallow.c'.
