env.mk already detects the location of the include path (which may or
may not have 'dpdk' in the name depending on the DPDK version), so put
that into a DPDK_INC_DIR variable and use it in the libnuma check so we
find the correct rte_config.h location.
Also check if rte_config.h exists before trying to pass it to grep -
this prevents error messages when running 'make clean' using the dpdk
submodule, because the rte_config.h file is removed before the other
SPDK directories get a chance to run 'make clean'.

It should only be used internally in vhost.c under g_spdk_vhost_mutex.
Also, this patch temporarily gets rid of return codes for

First, improve packing of spdk_bdev_io. Move any
fields which must be zeroed into the first cacheline.
Also change type and status from enums (needing 4 bytes)
to int16_t which is still a far bigger range than
needed.
Next, modify spdk_bdev_get_io to only zero the
first cacheline (actually a bit less).
SPDK_BDEV_IO_TYPE_INVALID is also added, making it
explicit that 0 is an invalid value for the IO type.
Previously this was somewhat inferred.
There are still additional improvements that can
be made to this area - primarily combining
spdk_bdev_get_io() and spdk_bdev_io_init() into
a single function.

split, gpt and error all have a lot of similar code, and
are based on the presumption of one or more "partition" bdevs
on a "base" bdev. This results in quite a bit of duplicated
code between these three bdev modules. The error bdev
module does follow this same model - it just always has only
a one-to-one mapping between the error bdev and its base bdev.
As all of the modules move to allocating their own bdev_io
rather than allowing for adjusting an existing bdev_io and
resubmitting it, there will be even more duplicated code
between these modules.
So this patch adds a set of helper functions in the common
bdev library to eliminate all of this duplicated code.
This patch also moves the split module to use it - future
patches will also convert gpt and error.

Added new callbacks to notify about socket connection status.
As destroy_device is used for virtqueue processing *pause* as well as
connection close, the user has no distinction between those.
Consider the following scenario:
rte_vhost: received SET_VRING_BASE message,
calling destroy_device() as usual
user: end-user asks to remove the device (together with socket file),
OK, device is not *in use* - that's NOT the behavior we want
calling rte_vhost_driver_unregister() etc.
Instead of changing new_device/destroy_device callbacks and breaking
the ABI, a set of new functions new_connection/destroy_connection
has been added.

2 locks are executed in 2 places in opposite orders.

(A)
* fdset_event_dispatch() start
* pfdentry->busy = 1; (lock #1)
* vhost_user_read_cb() start
* vhost_destroy_device() start
(B)
* rte_vhost_driver_unregister() start
* pthread_mutex_lock(&vsocket->conn_mutex); (lock #2)
* fdset_del()
* endless loop, waiting for pfdentry->busy == 0 (lock #1)
(A)
* vhost_destroy_device() end
* pthread_mutex_lock(&vsocket->conn_mutex); (lock #2)
(mutex already locked - deadlock at this point)
Thread B has locked vsocket->conn_mutex and is in while(1)
loop waiting for given fd to change it's busy flag to 0.
Thread A would have to finish vhost_user_read_cb() in order
to set busy flag back to 0, but that can't happen due to
the vsocket->conn_mutex lock.
This patch defers the fdset_del(), so that it's called outside of
vsocket->conn_mutex.

1) Change each split_disk to just point to a
split_base structure and drop the extra base_bdev
member. We can get the bdev from the split_base.
2) Simplify the names a bit for some of the members:
split_base::base_bdev to split_base::bdev and
split_disk::split_base to split_disk::base.

gencnt is no longer really used since there is no more
differentiation between "soft" and "hard" reset. The
original idea was that a hard reset would complete I/O
known to the bdev layer even if the underlying bdev
module had not actually completed it yet. We do not
actually support that concept, and it was a bit flawed
anyways.

This function was unnecessarily exposed in public vhost headers.
Controller-constructing functions now take string cpumask param.

This is useful for places that want to use the size of an NVMe
spec-defined field without having an instance of the corresponding
structure.
Specifically, we can use SPDK_NVME_CTRLR_SN_LEN to replace MAX_SN_LEN
in nvmf.h.
