b36face57d lvol: remove destruct_req from lvol store
Since destroy_lvol_bdev was implemented, it is now more convinient
to call destroy/unload for lvol store explicitly.
Rather than using lvs struct to pass a request checked on each
lvol close/destroy.

4219407a93 lvol: destroy_lvol_bdev implementation
This patch fixes lvol delete behaviour.
First, we look if there are any dependencies that disallow lvol deletion.
If there are any (i.e. dependent clones) we fail.
Otherwise we delete lvol and unregister associated bdev.

destroy_bdev no longer deletes lvol.

Fixes #345

03b12a98b2 bdev/virtio: support event index
This fixes intermittent failures with QEMU's virtio-scsi-pci
device.

Apparently, from time to time QEMU enters a broken state in
which it doesn't turn off the NO_NOTIFY flag. This flag should
be set only for the period of time virtqueues are being processed,
but QEMU makes it set all the time. This makes us not signal any
I/O submissions - SPDK thinks the device is currently processing
notifications so it will pick up our I/O automatically, but in
realitly it won't and we end up with a deadlock.

I believe kernel virtio driver doesn't hit this issue because of
event index feature. If negotiated, the NO_NOTIFY flag won't be
used at all. Initial tests show that the issue is indeed gone
with this patch.

Event index for SPDK virtio is not particularly useful when using
a poll-mode device, but it doesn't do any harm. It can be further
optimized in the future, but macro-benchmarks don't show any
performance difference compared with the legacy notification
handling so there's no hurry.

587002f511 virtio: expose virtio descriptors as soon as possible
With upcoming event index patch we will need
to keep track of how many descriptor chains we
have really put into the avail vring. This patch
is a step towards that.

Our virtio layer abstracts away descriptor chains
as "requests". We can start requests, add descriptors
to them, and finally flush them. So far we used to put
any descriptors directly into the virtqueue desc ring,
and made them visible to the device only through
virtqueue_req_flush().

All of our virtio bdev modules currently flush the
virtqueue after adding each single request, but the
docs for the virtio API say it's possible to start
multiple subsequent requests and flush them all at
once. This was conceptually broken so far and only
the last request would be exposed to the device.

It's now fixed and subsequent requests are put
into the avail vring as soon as they're complete
(either the next request is started, or the
virtqueue is flushed).

a2142f3a33 bdev/qos: add the QoS rate limiting support on bdev
This patch is to add the basic support of QoS on bdev.

Including two major functionalities:

1. The QoS rate limiting algorithm:
	a. New IO will be always queued first also under
	   the no memory condition
	b. Start the QoS IO operation based on the limit
	c. A poller started in each millisecond to reset
	   the rate limit and send new IOs down
	d. The rate limit is based on the millisecond and
	   converted from user configurable IOsPerSecond

2. The Master Thread management:
	a. Add a per bdev channel_count
	b. Whenever QoS is enabled on bdev, if QoS bdev
	   channel is not created, create the QoS bdev
	   channel and assign the QoS thread
	c. When new IOs coming from different channels
	   (threads), pass the IOs to the QoS bdev channel
	   through the thread event
	d. When the IOs are completed from the QoS bdev
	   channel, pass the IOs back to its orignal
	   channel(thread)
	e. Destroy the QoS bdev channel when it is the
	   last bdev channel for this bdev. Defer the
	   destruction if current thread is not QoS thread

4d36735401 bdev: rework bdev module registration
Currently SPDK_BDEV_MODULE_REGISTER() take many parameters. Extending it
(eg for incoming JSON configuration dump/load) is quite challenging and
error prone. As we are already here in next patches, rework this macro
to take one parameter - the pointer to struct spdk_bdev_module_if.

This patch also remove following macros:
SPDK_GET_BDEV_MODULE - this is not really needed, to find module outside
module translation unit use spdk_bdev_module_list_find()

SPDK_BDEV_MODULE_ASYNC_INIT and SPDK_BDEV_MODULE_ASYNC_FINI - replaced
by bool fields in spdk_bdev_module_if struct.

The lvol uuid is stored as an xattr for each lvol blob; if an lvol blob
without a uuid xattr is encountered, the lvol bdev will not report a
uuid for now (it will be set to all zeroes, which will be treated as
no uuid available by the generic bdev layer).

cb5178ea40 lvol: set default cluster size to 4MiB
Blobstore default cluster size is currently 4MiB,
but default lvol cluster size overrides it to 1GiB.

Additionally add -c flag in lvol tests to set cluster
size for tests.

1GiB was fine without thin provisioning, but we do not
want to allocate and copy 1GiB of data for newly allocated
clusters on thin provisioned logical volumes.

Note that 4MiB is same as default for Linux LVM.

lvol test case 601 had to be modified to create a malloc
LUN less than size of default cluster size.  This test is
supposed to fail - without the change here, creating the
lvolstore would work, but the script still considered it a
PASS.  Defer fixing that to a separate patch - for now just
keep the same test process.
