In SPDK 19.07, DIF insert and strip is supported for TCP transport of NVMe-oF
target, and DIF reference tag remap is now supported for partitioned virtual
bdev modules.
This patch updates CHANGELOG to reflect these updates.
If summarizing shortly,
DIF insert/strip is supported in the NVMe/TCP target. User can choose
DIF insert/strip or pass-through based on the use case. DIF reference tag

This option was intended to enable the user to disable the c2h_option,
but because of the way arguments filter down through the python script,
it was actually impossible to disable the optimization.
My understanding is that typically we will want to keep this
optimization enabled on most systems, but the option should work like it
says it does.
Also, align the implementation of this function with the other ones on
the RPC i.e. use the store_true, store_false paradigm.

By now (5.1 is released), the Linux kernel initiator supports the

it (5.0) was EOL-ed. As such, lets open it up @ spdk by default.
Doing so provides a notable performance improvement: running perf with
iodepth of 64, randread, two threads and block size of 512 bytes for 60s
("-q 64 -w randread -o 512 -c 0x5000 -t 60") over the VMA socket acceleration
library and null backing store, we got 730K IOPS with the success
optimization vs 550K without it.

To allow for interop with older kernel initiators, we added

This is an attempt to fix device hotremove with VFIO.
A soft device hotremove request through sysfs [1] would
currently just block until the SPDK process manually
releases that device - e.g. upon an RPC request.
VFIO won't get unbound from the device untill userspace
releases all its resources. VFIO can signal a pending
hotremove request by kicking any file descriptor provided
by the userspace - and DPDK does provide such descriptor -
but SPDK does not listen on it.
DPDK does offer handy API to listen and in this patch
we make use of it inside our env/pci layer. Within
a DPDK callback we set an internal per-device hotremove
flag, which upper-layer SPDK drivers can poll with a new
env API - spdk_pci_device_is_removed().
The VFIO hotremove event will be sent to primary
processes only, so that's where we listen.
We make use of this new API in the NVMe hotplug poller,
which will process it just like any other supported
hotremove event.

Historically, all memory returned from spdk_*malloc()
used to be physically contiguous, hence it could be
addressed by offsetting just a single physical address.
Since DPDK dynamic memory management came along, the
above is no longer true. Memory returned from spdk_*malloc()
doesn't have to be physically contiguous anymore. The
phys_addr returned from spdk_*malloc() only applies to
the beginning of the allocated buffer and user can't
possibly know how big that "beginning" is.
The phys_addr parameter in spdk_*malloc() is useless on
its own in most cases and only suggests that the returned
buffer is physically contiguous, which is wrong.
This information can be returned from spdk_vtophys(),
which is the only safe way to retrieve physical addresses.
That's why phys_addr param in spdk_*malloc() is now
deprecated.

iSCSI target will need to get data block size except for metadata.
Other SPDK application may need to get the same information
future. Hence this patch adds an new API spdk_bdev_get_data_block_size
to bdev layer. In the header file, spdk_bdev_get_data_block_size
is located next to spdk_bdev_is_md_interleaved to avoid confusion
by new users.

This function add possibility to check if there are any scheduled operations
on particular thread.
Return from spdk_thread_poll() will be used as a way to load-balance and
signify if any work was performed during the single iteration.
A poller could return 0, but still be registered.
This helps especially in fio_plugin that only checked active_pollers or
messages via spdk_thread_poll().

Default 'unmap' option stays as it was.
'Write_zeroes' comes useful when one wants to make sure
that data presented from lvol bdevs on initial creation presents 0's.
'None' will be used for performance tests,
when whole device is preconditioned before creating lvol store.
Instead of performing preconditioning on each lvol bdev after its creation.

strip_size as an rpc param is now deprecated and can be removed
in a future release. Either strip_size or strip_size_kb can be
used but only one of them or the rpc will fail.
Internally we maintain both fields because strip size always
comes in as KB but we convert it to blocks so having both elements
makes it clear for developers what they're looking at.
JSON output includes both strip_size and strip_size_kb.

Note: ocf build in autobuild.sh now needs to build
include/spdk/config.h before building the ocf library,
to ensure that header is available in a clean build
