The MDS expects to be able to perform writes to OSDs even
if the full ratio has been reached, in order to journal
file deletions to free space.

OSDs that for some reason get behind on processing their op queue break
expect_alloc_hint_eq(), as it pokes the FS and not the journal. Fix it
by flushing the journal before proceeding with anything else.

Add flush_journal admin socket command to be able to flush journal to
the permanent store for online osds. (For offline osds we already have
ceph-osd --flush-journal.)

Instead of copying the files in the ceph repository, which is less
convenient.
When building the headers are ignored, even though they do
not exist. When creating the tarbal with make dist, it fails because
they cannot be found. I misread src/gf_int.h to be include/gf_int.h and
wrongfully thought the submodules were to blame. This is why they were
removed shortly after being added.

Only rbd and mount_ceph need secret.c, and only secret.c needs libkeyutils;
remove it from LIBCOMMON_DEPS so it's not a dependency for everything,
remove secret.c from libcommon.a, and add it to mount.ceph/rbd's sources;
add LIBKEYID_LIB to mount.ceph/rbd's LDADD.

Since all we really need on a snapdir is the context, we really only
need it to be !missing. However, it might become !missing before it
becomes !unreadable. That allows ops to end up in the
waiting_for_degraded queue before one in waiting_for_unreadable is
woken, which allows the ops to be reordered. Rather than reintroduce an
extra waiting_for_missing queue, simply require !unreadable for snapdir
(which implies !misssing).

Otherwise, we might get into a situation where the primary
forgets about a stray pg. This is simpler and does not
increase the number of notifies by much.

The previous logic should have kept the current best info if it found a
replica which best could log-recover, but p couldn't. However, the
continue in that loop advanced the inner loop instead of the outer loop
allowing the primary case to take over in cases where best had a longer
tail. Instead, we will prefer the longer tail regardless of the other
infos to simplify the logic.

Not handling the error return from cmd_getval() may leave uninitialzied
values, which can cause issues, specially with non-string values.
