Add more large blob test cases

New test cases list commands that should work when memory is
limited. All memory allocation functions (*) learn to reject any
allocation larger than $GIT_ALLOC_LIMIT if set.

(*) Not exactly all. Some places do not use x* functions, but
malloc/calloc directly, notably diff-delta. These code path should
never be run on large blobs.

parse_object: avoid putting whole blob in core

Traditionally, all the callers of check_sha1_signature() first
called read_sha1_file() to prepare the whole object data in core,
and called this function.  The function is used to revalidate what
we read from the object database actually matches the object name we
used to ask for the data from the object database.

Update the API to allow callers to pass NULL as the object data, and
have the function read and hash the object data using streaming API
to recompute the object name, without having to hold everything in
core at the same time.  This is most useful in parse_object() that
parses a blob object, because this caller does not have to keep the
actual blob data around in memory after a "struct blob" is returned.

update-server-info: respect core.bigfilethreshold

This command indirectly calls check_sha1_signature() (add_info_ref ->
deref_tag -> parse_object -> ..) , which may put whole blob in memory
if the blob's size is under core.bigfilethreshold. As config is not
read, the threshold is always 512MB. Respect user settings here.

fix deletion of .git/objects sub-directories in git-prune/repack

Both git-prune and git-repack (and thus, git-gc) try to rmdir while
holding a DIR* handle on the directory.  This can leave dangling
empty directories in the .git/objects on platforms where directory
cannot be removed while they are open.

First call closedir() and then rmdir(); that is more logical ordering.

apply: do not leak patches and fragments

In the while loop inside apply_patch, patch and fragments are
dynamically allocated with a calloc. However, only unused patches
are actually freed and the rest are left to leak. Since a list is
actively built up consisting of the used patches, they can simply be
iterated and freed at the end of the function.

In addition, the text in fragments were not freed, primarily because
they mostly point into a patch text that is freed as a whole. But
there are some cases where new piece of memory is allocated and
pointed by a fragment (namely, when handling a binary patch).

Introduce a free_patch bitfield to mark each fragment if its text
needs to be freed, and free patches, fragments and fragment text
that need to be freed when we are done with the input.

perf: export some important test-lib variables

The only bug right now is that $GIT_TEST_CMP is needed for test_cmp to
work.

However, we also export the three most important paths for tests:

  TEST_DIRECTORY
  TRASH_DIRECTORY
  GIT_BUILD_DIR

Since they are available within test_expect_success, a future test
writer may expect them to also be defined in test_perf.
