Implement msgr2.1 wire protocol, available since nautilus 14.2.11
and octopus 15.2.5. msgr2.0 wire protocol is not implemented -- it
has several security, integrity and robustness issues and therefore
considered deprecated.

libceph: move msgr1 protocol specific fields to its own struct2020-12-14T22:21:50ZIlya Dryomovidryomov@gmail.com2020-11-12T15:31:41Zurn:sha1:a56dd9bf47220c3206f27075af8bdfb219a2a3cf
A couple whitespace fixups, no functional changes.

libceph: move msgr1 protocol implementation to its own file2020-12-14T22:21:50ZIlya Dryomovidryomov@gmail.com2020-11-12T14:48:06Zurn:sha1:2f713615ddd9d805b6c5e79c52e0e11af99d2bf1
A pure move, no other changes.
Note that ceph_tcp_recv{msg,page}() and ceph_tcp_send{msg,page}()
helpers are also moved. msgr2 will bring its own, more efficient,
variants based on iov_iter. Switching msgr1 to them was considered
but decided against to avoid subtle regressions.

libceph: separate msgr1 protocol implementation2020-12-14T22:21:49ZIlya Dryomovidryomov@gmail.com2020-11-12T11:55:39Zurn:sha1:566050e17e53db283d4e26b73b4b50556f97ce7b
In preparation for msgr2, define internal messenger <-> protocol
interface (as opposed to external messenger <-> client interface, which
is struct ceph_connection_operations) consisting of try_read(),
try_write(), revoke(), revoke_incoming(), opened(), reset_session() and
reset_protocol() ops. The semantics are exactly the same as they are
now.

In preparation for msgr2, make all protocol independent functions
in messenger.c global.

In preparation for msgr2, rename msgr1 specific states and move the
defines to the header file.
Also drop state transition comments. They don't cover all possible
transitions (e.g. NEGOTIATING -> STANDBY, etc) and currently do more
harm than good.

libceph: make con->state an int2020-12-14T22:21:49ZIlya Dryomovidryomov@gmail.com2020-11-09T13:11:26Zurn:sha1:30be780a87211de75b93935c20a0913e46744a3f
unsigned long is a leftover from when con->state used to be a set of
bits managed with set_bit(), clear_bit(), etc. Save a bit of memory.

It is set in process_ack() but never used.
