common/common_init: disable ms subsystem log gathering for clients

The log gathering causes large performance degradation to clients
with high message throughputs. This is hopefully a short-term
workaround until per-message logging can be replaced with an
efficient data recording system for post-incident analysis
use-cases.

Reviewed-by: Kefu Chai <kchai@redhat.com>

buffer: remove list _mempool member

This broke the C++ ABI by changing the list structure size.  Also, it's
not necessary as we can infer the mempool by looking at the other list
contents.  We don't (currently) have a need to map an empty list to a
particular mempool and have that state stick.

.gitignore: allow debian .patch files

The Ubuntu packaging layout with git-buildpackage assumes a
"debian/patches/" directory with several .patch files in it.

When upstream's .gitignore tells Git to ignore .patch files, we have to
edit that line out downstream. When we forget to do that downstream, it
can lead to missing patches and broken downstream builds.

Allow patches in the /debian/patches directory so it's easier to
maintain an Ubuntu package based on upstream's Git repo.

src/messages/MOSDMap: reencode OSDMap for older clients

We explicitly select which missing bits trigger a reencode.  We
already had jewel and earlier covered, but kraken includes all of
the previously mentioned bits but not SERVER_LUMINOUS.  This
prevents kraken clients from decoding luminous maps.

osd/PG: separate event for RemoteReservationCanceled

Right now we transparently map a RemoteReservationRejected into a
*Canceled event because this what peers send over the wire.  Even
once new peers start sending and explicit CANCEL, old peers will
still do so, so we'll maintain this mapping for a while.
