4c0eaac47a bdev: Create a separate bdev subsystem library
Much like bdev modules inside the bdev directory,
add a subsystems directory inside of event. The subsystem
specific code for the bdev library is placed in to
a separate library in that directory, breaking the
strict dependency of the bdev library on the event subsystem
code.

356e2ab20f event: remove spdk_app_init
In this patch, spdk_app_init will be merged into
spdk_app_start.
Due to this change, we need to change event_perf
to use spdk_app_start, since we cannot use spdk_app_init
anymore. So the related changes for event_perf is to
make it work with reactor framework.

This patch adds property of transport protocol id to spdk_scsi_dev.
This allows to change it depending on which appliation is using
the device. Previously only iSCSI was used for all.

Setting protocol id is done at the time when device is added to
vhost controller (vhost) or target node (iSCSI).

Please note that for SPDK vhost SAS protocol id is used,
as that is what kernel vhost reports as well.

d237aba3b9 vhost: separated scsi layer from vhost.c
Implemented vhost abstraction layer in preparations for vhost-blk.
Generalized vhost interface and separated vhost-scsi code.

Code placement:
vhost.h
 * vhost_startup() & shutdown()
 * public generic controller API

vhost_internal.h
 * includes rte_vhost.h from DPDK
 * struct spdk_vhost_dev (it has to be inherited by vhost_scsi)
 * vhost_dev management
   * register/unregister() to be used in new_device()/destroy_device()
   * construct/destruct() to be used on permanent creation/destruction.
 * reactor core management

vhost_scsi.h
 * spdk_vhost_scsi_dev management
   * reading VhostScsi section of vhost config file
   * creating/removing controllers
   * adding/removing devices to controllers

vhost_scsi.c
 * virtio scsi logic
 * new_device(), destroy_device()

c6745bc2b8 vhost: generalized spdk_vhost_dev struct
Moved controller-related variables from spdk_vhost_scsi_controller to
spdk_vhost_dev. Generalized vhost to operate on non scsi-specific
controller struct.

Now spdk_vhost_scsi_dev contains direct spdk_vhost_dev field instead
of a pointer. This means there is no more allocation/deallocation
on poller start/stop.

2e3f07ac40 bdev: add spdk_io_channel parameter to spdk_bdev_reset
This ensures that all spdk_bdev_io structures now have
an attached channel, simplifying some future work around
things like counting the number of outstanding IOs for
a given channel (which otherwise would have had to
account specially for resets).

Reset semantics are still that they affect the entire bdev
and not just the channel it was submitted on.

b9bcc3531e bdev: make enum spdk_bdev_io_status private
The user should not see the bdev_io status directly; the NVMe and SCSI
error code wrappers provide the ability to translate to the desired
format regardless of what kind of error is stored inside the bdev_io.

Replace the spdk_bdev_io_completion_cb status parameter with a bool
simply indiciating whether the I/O completed successfully.
