[PATCH RFC 0/6] Support rados locking

[Douglas Fuller <dfuller@redhat.com>]

Add decoding support for some commonly exchanged data structures.
Adapt Mike's code to serve as a generic client for cls::lock in userspace.

Discussion points:
Is this how we want to represent object classes in the kernel client?

This defines ceph_locker to contain ceph_locker_id and ceph_locker_info
from userspace. Is that what we want for adaptation of userspace data
structures (in this case std::map<locker_id_t, locker_info_t>)?

There are quite a few strings in these data structures. Do we want
to add utility functions to properly free them at some level?

Douglas Fuller (4):
  auth.c: added ceph_entity_name_encode
  osd_client: added single object method call
  cls_lock: add rados locking
  cls_lock: add support for lock_info

Mike Christie (2):
  Add support for userspace ceph DECODE_START.
  ceph: add start/finish encoding helpers
