Subject: Abort when cleaning up fails
When a fatal error triggers during cleanup, another attempt will be made to
clean up, which will likely lead to the same fatal error. So instead, bail out
when that happens.
src/patch.c (cleanup): Bail out when called recursively.
(main): There is no need to call output_files() before cleanup() as cleanup()
already does that.

Subject: Don't crash when RLIMIT_NOFILE is set to RLIM_INFINITY
* src/safe.c (min_cached_fds): Define minimum number of cached dir file
descriptors.
(max_cached_fds): Change type to rlim_t to allow storing RLIM_INFINITY.
(init_dirfd_cache): Set max_cached_fds to RLIM_INFINITY when RLIMIT_NOFILE is
RLIM_INFINITY. Set the initial hash table size to min_cached_fds, independent
of RLIMIT_NOFILE: patches commonly only affect one or a few files, so a small
hash table will usually suffice; if needed, the hash table will grow.
(insert_cached_dirfd): Don't shrink the cache when max_cached_fds is
RLIM_INFINITY.

Subject: Don't follow symlinks unless --follow-symlinks is given
* src/inp.c (plan_a, plan_b), src/util.c (copy_to_fd, copy_file,
append_to_file): Unless the --follow-symlinks option is given, open files with
the O_NOFOLLOW flag to avoid following symlinks. So far, we were only doing
that consistently for input files.
* src/util.c (create_backup): When creating empty backup files, (re)create them
with O_CREAT | O_EXCL to avoid following symlinks in that case as well.

Subject: Don't leak temporary file on failed ed-style patch
Now that we write ed-style patches to a temporary file before we
apply them, we need to ensure that the temporary file is removed
before we leave, even on fatal error.
* src/pch.c (do_ed_script): Use global TMPEDNAME instead of local
tmpname. Don't unlink the file directly, instead tag it for removal
at exit time.
* src/patch.c (cleanup): Unlink TMPEDNAME at exit.

Subject: Don't leak temporary file on failed multi-file ed-style patch
The previous fix worked fine with single-file ed-style patches, but
would still leak temporary files in the case of multi-file ed-style
patch. Fix that case as well, and extend the test case to check for
it.
* src/patch.c (main): Unlink TMPEDNAME if needed before moving to
the next file in a patch.
