Module initializaiton was made asynchronous recently
to support bdev modules like gpt which need to do
asynchronous I/O. But all modules now do any
asynchronous I/O in their examine() routines, and
init functions only do very basic operations to be
ready to handle examine() callbacks.
So simplify the bdev code and modules to go back to
a synchronous init procedure.

vbdev modules still open/close bdevs as normal, but
should open bdevs read only when tasting (i.e. reading
the GPT to see if there are SPDK partitions). When
a vbdev module is ready to claim the bdev for purposes
of creating virtual bdevs on top of it, it calls
spdk_vbdev_module_claim_bdev(). It can pass its
open descriptor as well to have it promoted to
write access (required for future vbdev modules like
logical volumes).
Note: error vbdev was changed to copy the base bdev
parameters one-by-one instead of a blind memcpy - we
do not want to copy the base bdev's vbdev_claim_module
into the new bdev!

Rename the existing ahs_data array in the PDU to just "ahs" to minimize
the necessary changes. We never actually dereference the ahs structure,
so its type is not important. (We can cast it later if we add support
for anything that requires an AHS.)

During RocksDB testing with MySQL, we found cases
where blobfs would try to update and sync the length
xattr on the underlying blob while an existing update
was already in progress. This was primarily driven
by RocksDB performing appends and syncs on the log
file from multiple writer threads.
The simplest way to fix this is to just process one
sync_request at a time. There could be a tiny bit
of inefficiency here if multiple threads are appending
and syncing a file in parallel - we can look at some
additional optimizations if we find a case where that
is noticeable.

This requires the following modifications to existing
bdev modules:
1) error and split now search their config sections
at examine time (instead of init) to see if the
bdev should be consumed by the vbdev module
2) gpt is simplified considerably - it no longer
needs to save bdevs to examine when
gpt initializes later
3) nvme must register its io device before registering
the bdev, since vbdevs may immediately start trying
to send I/O to the new nvme bdev

There are several possible usages of this information -
the first will be related to starting a poller for a bdev
channel when there are I/O that need to be retried.
Usually we can retry an I/O when a previous I/O completes,
but if there are no outstanding I/O, we need to start a
poller. This count will help us make that decision.

it up to spdk_bdev_scsi_readwrite().
spdk_bdev_scsi_read() previously passed task->transfer_len / blen rather

actually be using the transfer length field from the CDB (which is the
xfer_len parameter).

This patch address the issue:
https://github.com/spdk/spdk/issues/151.
For cache_append_no_cache in cache_ut testcase,
there is resource contention for buffer among two
threads in the following two functions.
Thread 0: cache_free_buffers
Thread1: __file_flush_done
When the thread1 execuctes __file_flush_done,
it calls the call back: __sem_post defined in
following statement in spdk_file_sync
_file_sync(file, channel, __sem_post, &channel->sem);
Thus Thread 0 will execute next function
cache_buffers, and it frees the buffer.
Then Thread 1 continues executing the remaining statements
in __file_flush_done with the assert function, and touches
the space already freed.
So it will be safe to move ahead the next buffer check.

vhost-net devices might keep track of last descriptors indices by
themselves, and assuming they initially start at 0, but that is not the
case for vhost-scsi. Initial last descriptor indices are set via
VHOST_USER_SET_VRING_BASE message, and we cannot possibly predict what
will they be. Setting these to vqueue->used->idx is also not an option,
because there might be some yet unprocessed requests between these and
the actual last_idx. This patch adds API for getting/setting last
descriptor indices of vrings, so that they can be synchronized between
user-device and rte_vhost.
The last_idx flow could be as following:
* vhost start
* received SET_VRING_BASE msg, last_idx is set on rte_vhost side
* created user-device, last_idx pulled from rte_vhost
* requests are being processed by user-device, last_idx changes
* destroyed user-device, last_idx pushed to rte_vhost
* *at this point, vrings could be recreated and another SET_VRING_BASE
message could arrive, so last_idx would be set*
* recreated user-device, last_idx pulled from rte_vhost

There is an issue when QEMU sets new memory table just after guest OS
starts booting. Then, if guest OS tries to issue any I/O to device (e.g.
using BIOS INT13h - EDD) it will get stuck because previous addresses of
mmaped memory might change.
To fix this issue, defer using the new mem table until after we receive
the first SET_VRING_ADDR message. SET_VRING_ADDR will be sent by QEMU
when guest OS virtio (e.g. virtio-scsi) driver starts initialization.
At this point it is safe to invalidate the old mem tables because there
will be no more outstanding IO at this point.

For now DPDK assumes that callfd, kickfd and last_idx are being set just
once during vring initialization and device cannot be running while DPDK
receives SET_VRING_KICK, SET_VRING_CALL and SET_VRING_BASE messages.
However, that assumption is wrong. For Vhost SCSI messages might arrive
at any point of time, possibly multiple times, one after another.
QEMU issues SET_VRING_CALL once during device initialization, then again
during device start. The second message will close previous callfd,
which is still being used by the user-implementation of vhost device.
This results in writing to invalid (closed) callfd.
This patch destroys vhost device before setting callfd, kickfd and last
vring indices. It will be recreated right after (with updated vring
data).

When destroying a connection, we need to check if we got to
full feature phase before freeing any io channels. This is because
the io channels are only allocated as part of a successful login.
The Calsoft iSCSI test suite has tests which will fail login.
Since the test system was just using a malloc backend with memcpy,
so even though a channel was NULL in some cases, it was never used
since the memcpy engine doesn't need it.

First step is do not destroy an existing device in
vhost_user_set_mem_table(). This is because we may
still be processing I/O via INT13 while QEMU is setting
up the mem tables for OS boot.
The primary part of this patch though is to defer
using the new mem table until after we receive the
first SET_VRING_ADDR message. SET_VRING_ADDR will be
sent by QEMU when guest OS virtio-scsi driver starts
initialization. At this point it is safe to invalidate
the old mem tables because there will be no more
INT13 I/O at this point.

The RDMA protocol this module uses is strictly ordered,
which means messages are delivered in exactly the order

arrive out of order. This patch attempts to handle

Separate the data required to post a recv from the
data required to send a response. If a recv arrives
when no response object is available, queue the
recv.
