perfcounters: use simple names
We don't need to uniquely identify ourselves in the global namespace with
the PerfCounter name.. only in the current process. Collectd will handle
the per-daemon naming part.

test_filestore_idempotent: simple tool to generate a worklaod of non-idempotent operations
Generate a workload of operations that are non-idempotent. These are:
transaction {
clone A -> A.($n-1)
write $n to A
}
$n++
loop!
If we apply any transaction to the file system more than once, we will
find that the A.$n object does not contain $n, but instead contains
some larger value.
First run in 'write' mode to generate a workload and fake a crash.
Then run in 'verify' mode to see if the result was bad.

ceph.spec: work around build.opensuse.org
The redhat-rpm-config isn't installed on build.opensuse.org, which means
the processor is set to i386 instead of something less ancient. This

cephtool: ability to send commands directly to osds
This makes commands beginning with 'tell <target>' magic in that they go
to the given target instead of to the monitor. This is slightly odd, but
I think it gives the most natural interface for the user, with the tool
Doing The Right Thing for you. E.g.,
ceph tell <someone> something (direct to some daemon)
ceph do something (goes to monitor to do X)

PG: Fix log.empty confusion
Previously, log.empty meant that the log.head was everion_t(). However,
it was in a few places used to mean that log.head == log.tail. Now,
log.empty means log.head == log.tail and log.null() indicates that

Interval tree is an optimized data structure for representing and
querying intervals. Elementary intervals are represented as nodes of an
avl tree and the corresponding data is stored on these nodes based on a
concept of span. This representation allows log(n) (where n is the
number of data) storage. The balanced avl tree allows a log(n) query.
The implementation is a template class that is instantiated based on
parameters : - Interval type - Data type

osd: fix race between op requeueing and _dispatch
If a message is working it's way through _dispatch, and another thread
requeues waiting messages under pg->lock (e.g.
osd->take_waiting(waiting_for_active)), the requeued ops are processed
after the one _dispatch() is chewing on, breaking client ordering.
Instead, add a new OSD::requeue_ops() that reinjects ops back into the
op queue by feeding them to the _handle_*() helpers. Those do last minute
checks before enqueuing the ops.
