[PATCH v3 0/4] Importing and exporting stashes to refs

["brian m. carlson" <sandals@crustytoothpaste.net>]

Stashes are currently stored using the reflog in a given repository.
This is an interesting and novel way to handle them, but there is no way
to easily move a stash across machines.  For example, stashes cannot be
bundled, pushed, or fetched.

Let's solve this problem by allowing users to import and export stashes
to a chain of commits.  The commits used in a stash export contain two
parents: one which is the pointer to the next exported stash (or to an
empty commit with no parents if there are no more) and the second is the
stash commit that would normally be stored in the reflog.

Changes from v2:
* Fix uninitialized strbuf.
* Avoid C99-style initializations.

Changes from v1:
* Change storage format as suggested by Junio.
* Rename to GIT_OID_GENTLY.
* Remove unnecessary initializations.
* Use ALLOC_GROW_BY.
* Ensure completely reproducible exports.
* Avoid size_t.
* Various other code cleanups.
