libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridge
This change genericizes the cache mechanism implemented in commit
8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as
a client. The cache mechanism is fundamentally equivalent, with some
minor changes:
- Change cache key from uid_t to uint64_t.
- Modify the cache add logic to locate and use an entry with a
matching ID, should it already exist. This addresses a bug in
the existing mechanism where an expired entry supercedes a newly
added entry in lookup, causing repeated adds and flushing of a
cache bucket.
The fuse group cache is disabled by default. It can be enabled via
the 'gid-timeout' fuse-bridge translator option and accompanying
mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).
BUG: 800892
