We may first learn our fsid from any of the mon, osd, or mds maps
(whichever the monitor sends first). Consolidate checks in a single
helper. Initialize the client debugfs entry then, since we need the
fsid (and global_id) for the directory name.
Also remove dead mount code.

When we open a monitor session, we send an initial AUTH message listing
the auth protocols we support, our entity name, and (possibly) a previously
assigned global_id. The monitor chooses a protocol and responds with an
initial message.
Initially implement AUTH_NONE, a dummy protocol that provides no security,
but works within the new framework. It generates 'authorizers' that are
used when connecting to (mds, osd) services that simply state our entity
name and global_id.
This is a wire protocol change.

This simplifies much of the error handling during mount. It also means
that we have the mount args before client creation, and we can initialize
based on those options.

Since we've increased the max mon count, we shouldn't put the addr array
on the parse_mount_args stack. Put it on the heap instead.

Get rid of separate max mon limit; use the system limit instead. This
allows mounts when there are lots of mon addrs provided by mount.ceph (as
with a host with lots of A/AAAA records).

Writeback doesn't work without the bdi set, and writeback on
umount doesn't work if we unregister the bdi too early.
