Update bench.sh/plot tool to cover ISA backend.
ISA will output a fake echinique 'cauchy_good' so the plot tool
don't need to be changed.

Previously we were iterating through the parts, creating hash of the
parts etags (as S3 does for multipart uploads). However, swift just
calculates the etag for the empty manifest object.

We didn't send the etag back correctly. Original code assumed the etag
resided in the attrs, but attrs only contained request attrs.

doc: Update for OpenStack Juno.
New users working with Nova (Juno) noted that libvirt settings are now under a [libvirt] section, and truncate the leading libvirt_. Made subsections for Havana and Icehouse, added a new subsection for Juno.
Return a pointer to a contiguous range of the bufferlist, rebuilding
into a contiguous region as needed. For now, if we need to rebuild,
we just do the whole thing. We can obviously optimize this later to
rebuild on the necessary region, but this is good enough for the
(presumably) common case where the needed region is already in fact
contiguous.

Dear list,
I have met this when I was using radosstriper C API. My program is
roughly like this:
rados_striper_aio_write
rados_aio_flush
rados_aio_wait_for_safe
rados_aio_release
rados_striper_destroy
rados_ioctx_destroy
rados_shutdown /Hangs here/
In most time, this works well, But the programm occasionally
hangs forever. Output of gstack:

It is obvious that librados::Rados::shutdown is not a thread-safe
function here. It will hang forever. The culprit of this is when
CompletionData is released, it will first notify
"rados_aio_wait_for_safe" to continue, and CompletionData will call
put() to release other data. But if the main thread(Thread 1 here) runs
fast enough, rados_striper_destroy will be executed before other
thread(Thread 4 here)'s releasing refcnf. In this situation, main thread
runs Rados::shutdown() while other thread runs Rados::shutdown() in the
same time.
My suggestion is to let RadosStriperImpl::aio_flush to block until all
the CompletionData has been released. This makes sure other thread will
never call rados_shutdown.
The acting array was incorrectly including the primary and up_primary.

If the base pool does not exist, we need to avoid dereferencing pi.
This simplest fix is to return with POOL_DNE early and skip all of the
checks.
Note that there is one other small semantic change in this function: if
we are using the precalc_pgid then base_oloc pool has to match. But
the list_objects() caller does that, so we're fine.
