This moves our version pointer up so that we don't re-log (by re-consuming)
log messages to /var/log/ceph/ceph.log on ceph-mon restart. OTOH, it means
we rewrite the summary of the last 50 messages, but we consider that to be
relatively cheap (and something we *always* did prior for bobtail and
earlier anyway).

Set an interval to periodically write a full copy of the map that is lower
than the trim point (which is generally a very large number of commits).

In order of interest/priority:
- our latest monmap version
- a backup monmap version created during sync start, if the store
appears to be in a post-aborted sync state
- a mkfs monmap version
If none of these are found, we should go ahead and try to build a
monmap from ceph.conf to join an existing cluster.

If by fate we end up attempting a store sync after failing at
least one before, we might not have a monmap to read from the
store to backup. Therefore, in that case, we shall backup the
current monmap being used by the monitor.

Out of order journal entry writes using aio may cause entry

With OSD sharing data and journal, the previous code created the
journal partiton from the end of the device. A uint32_t is
used in sgdisk to get the last sector, with large HD, uint32_t
is too small.
The journal partition will be created backwards from the
a sector in the midlle of the disk leaving space before
and after it. The data partition will use whichever of
these spaces is greater. The remaining will not be used.
This patch creates the journal partition from the start as a workaround.

When starting we often loop over many daemon instances. Currently we stop
on the first error and do not try to start other daemons.
Instead, try them all, but return a failure if anything did not start.

Call observers so that the logging infrastructure gets initailized and we
start logging. Otherwise, unless a default log setting has been modified,
we won't start logging until we daemonize, and we won't get the nice
version banner in the log file.
Unlike the previous attempt to fix this (a3091774), we do this after all
of the lockdep initialization has completed.
