fuse: add basic infrastructure to support idmappings
Add some preparational changes in fuse_get_req/fuse_force_creds
to handle idmappings.
Miklos suggested [1], [2] to change the meaning of in.h.uid/in.h.gid
fields when daemon declares support for idmapped mounts. In a new semantic,
we fill uid/gid values in fuse header with a id-mapped caller uid/gid (for
requests which create new inodes), for all the rest cases we just send -1
to userspace.
No functional changes intended.
