  libceph: drop ceph_auth_{create,update}_authorizer() (2020-12-14 23:21:50 +0100)

There is a build conflict caused by the split of crypto/sha.h into
crypto/sha1.h and crypto/sha2.h that affects net/ceph/messenger_v2.c.
The resolution is to include the latter, done in for-linus-merged
just in case.

----------------------------------------------------------------
The big ticket item here is support for msgr2 on-wire protocol, which
adds the option of full in-transit encryption using AES-GCM algorithm
(myself).  On top of that we have a series to avoid intermittent
errors during recovery with recover_session=clean and some MDS request
encoding work from Jeff, a cap handling fix and assorted observability
improvements from Luis and Xiubo and a good number of cleanups.  Luis
also ran into a corner case with quotas which sadly means that we are
back to denying cross-quota-realm renames.
