As a follow-on to 49d114f1ff,
increment the "extra" version field so clients can easily
determine if they have a version of librados that properly
translates C API operation flags.

Note that this will only get used if the kernel is new enough; if it is
older than 3.5 the option will get disabled and extsize will not be used
even if the option is set to true.
This partially reverts 01cd3cdc72.

Old kernels have an XFS bug that exposes uninitialized data when the
extsize hint is set and only partially written. This is fixed by Linux
commit aff3a9edb7080f69f07fe76a8bd089b3dfa4cb5d, documented in XFS bug
http://oss.sgi.com/bugzilla/show_bug.cgi?id=874, and tested by XFS
test xfs/229 to prevent regressions.
Notably the original bug affects kernel 3.2, which is widely deployed with
ubuntu precise 12.04.

This is for use in CephFS disaster recovery. When
the metadata pool has been forcibly reset to a single-MDS
metadata tree, we would like to reset the MDSMap to match.

Note: It does not do the merging work if
either of the source diff files is stripped,
since which complicates the process and is
rarely used

Avoid taking the PG lock for a canceled read op (if we are lucky). Recheck
after the lock is taken for good measure.

We can't use the synchronous completion callbacks (in fast dispatch

If we are not write ordered, continue with cache checks so that we can
(among other things) proxy reads while promoting.
Note that this may reorder reads for clients, but we've decided that's okay.

Remove the triggering op from the internal promote machinery.
We keep the optional op arg to promote_object() only because we may
block on an object other than the original obc.

This currently enumerates all cache modes except none, and we don't
arrive in this function when caching is disabled. And creating a whiteout
is not cache_mode dependent. Simplify!

For now, we still always pass it. In preparation, however, we modify
promote_object() so that it will work when op is null.

The command blocks and ensures we have the latest map from the
mon. This is useful in testing and to "unstick" clusters in some
odd situations.
