Pointers to directory entries do not remain valid after a call to
dent_insert.
Noticed in the course of importing a small Subversion repository
(~1000 revs); after setting up a dirent for a certain path as a
placeholder, by luck dent_insert would trigger a realloc that
shifted around addresses, resulting in an import with that file
replaced by a directory.

dirent is #define’d to mingw_dirent in compat/mingw.h, with the
result that
obj_pool_gen(dirent, struct repo_dirent, 4096)
creates functions with names like mingw_dirent_alloc and
references to dirent_alloc go unresolved. Rename the functions
to dent_* to avoid this problem.

repo_tree maintains the exporter's state and provides a facility to to
call fast_export, which writes objects to stdout suitable for
consumption by fast-import.
The exported functions roughly correspond to Subversion FS operations.
. repo_add, repo_modify, repo_copy, repo_replace, and repo_delete
update the current commit, based roughly on the corresponding
Subversion FS operation.
. repo_commit calls out to fast_export to write the current commit to
the fast-import stream in stdout.
. repo_diff is used by the fast_export module to write the changes
for a commit.
. repo_reset erases the exporter's state, so valgrind can be happy.
[rr: squelched compiler warnings]
[jn: removed support for maintaining state on-disk, though we may
want to add it back later]
