d92f0f75ca log: rename SPDK_TRACELOG to SPDK_DEBUGLOG
This matches the name to the behavior and prepares for addition of a new
log macro for "info" log level.

afb3f73869 nvmf: always zero admin ctrlr-to-host data buffers
For admin commands with controller to host transfers, make sure no
uninitialized data is returned to the host.  This allows us to remove a
few other memset()s in per-command handlers.

ea952fcaf2 bdev/split: remove resubmit logic
Issue each I/O to the base bdev as a new discrete I/O rather
than resubmitting the original I/O.  This enables some
upcoming changes to better handle queueing and reset-related
work at the generic bdev layer, which will also deprecate
the resubmit I/O logic.

900aef2c99 bdev/split: simplify structures and naming
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.

f054577df1 bdev: remove gencnt
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.

c2175d2c51 virtio: add initial rev of virtio-scsi initiator bdev module
Supports both PCI mode (for usage in guest VMs) and
vhost-user mode (for usage in host processes).  The rte_virtio
subdirectory contains a lot of code lifted from the DPDK
virtio-net driver.  Most of the PCI and vhost-user code is
reused almost exactly as-is, but the virtio code is drastically
rewritten as the DPDK code was very network specific.

Has been lightly tested with both the bdevio and bdevperf
applications in both PCI and vhost-user modes.

Still quite a bit of work needed - a list of todo
items is included in a README in the module's directory.

1b67738c65 vhost: move linux virtio headers to include/
These headers are needed on systems that have old
kernels without virtio_scsi.h and virtio_types.h.
Move them out of the vhost directory and into include
so that they can be used by an upcoming virtio-scsi
initiator bdev module.

3c423f4099 nvmf: Turn RDMA req processing into a state machine
Formalize a state machine around request processing.
The state is advanced by calling
spdk_nvmf_rdma_request_process().

This clarifies the implementation considerably and
cleans up a few corner cases. Unfortunately, the diff
is also enormous and there does not appear to be a
way to reduce it.
