This is the initial commit for "blobfs", a lightweight
filesystem built on top of the SPDK blobstore.
Also included in this patch:
1) a shim for using SPDK bdevs as the backing store for
SPDK blobstore/blobfs
2) documentation for using blobfs as the storage engine
with RocksDB
3) scripts for running a set of workloads and collecting
profiling data with RocksDB and blobfs
See doc/blobfs/getting_started.md included in this commit
for more details on blobfs, including some of the current
limitations.

A few instances of DPDK_INC were added after the env library abstraction
was introduced; replace them with the correct ENV_CFLAGS variable
defined by env.mk.

This is the initial commit for the "blobstore", a lightweight,
highly parallel, persistent, power-fail safe block allocator.
Documentation will be added in future patches.

The user now must choose the name for each AIO bdev. This
provides consistency for names across restarts.

Simplify code that previously needed to check for subsystem type by
factoring out the discovery controller operations into a new ops

All devices must be specified by BDF. Add support for scripts
to use lspci to grab the available NVMe device BDFs for the

SPDK_COUNTOF works like sizeof, except it returns the number of elements
in an array instead of the number of bytes.

After checking the code, aerl in our session is 0,
so there will be only 1 AER. So currently,
we will only handle 1 AER case.
When the AER event is triggered by real NVMe device owned
by the subsystem, it notifies all sessions belonging to
the subsystem.

vtophys_get_paddr() and vtophys_get_dpdk_paddr() are doing similar
things; combine them into one function that works for all DPDK
memory addresses.
Part of the vtophys test is temporarily disabled until the next commit,
which will register all DPDK memory at startup and stop lookiing up
addresses at runtime.

This patch makes spdk_scsi_lun_construct behave as documented.
spdk_scsi_lun_construct will return only newly created LUN.
If LUN with that name already exists, NULL will be returned.
Unit test relevant to this behaviour is now changed to show
this functionality is now working.

This is necessary to prevent claiming the same LUN twice
and properly cleanup in case of an error during spdk_scsi_dev_construct.
This patch addresses three issues:
- spdk_scsi_lun_claim error is correctly handled in spdk_scsi_dev_add_lun
- on error when constructing scsi dev, it is now correctly removed along with attached luns
- spdk_scsi_dev_destruct not only unclaims, but calls spdk_scsi_lun_destruct on each lun in dev
Unit tests relevant to this behaviour are changed to show this functionality is now working.

This patch adds two new unit tests for scsi device:
- creating two different devices, each containing the same lun
- creating one device, with the same lun twice
As noted in code, three asserts are incorrectly set to show functionality
that is not working currently.
Next patch in series implements that functionality and changes asserts
in the unit tests.

Make sure that the output strings are not NULL before comparing them
with strcmp(). This silences some scan-build warnings.

The host and port output parameters point into the (non-const) char *ip,
so it makes more sense for them to be non-const as well.
This allows the flexibility to pass non-const char pointers as the
output parameters, which will be used in the nvmf_tgt/conf.c parsing
code.

For namespaces with end-to-end protection information, metadata size
of exactly 8 bytes, and extended LBA configured, the NVMe driver would
calculate the size of the data block incorrectly. The NVMe spec has a
special provision for this specific case (8-byte metadata only) and
PRACT = 1 that requires that the host does not send the metadata as part
of the host memory buffer.
To fix this, clean up the calculation of the per-block data transfer
size by adding a new extended_lba_size field in the namespace, which
represents the total size of data to be transferred per block based on
the namespace's configured metadata size and whether it transfers
metadata as part of the data buffer. Then add the special case for
PRACT = 1 and PI configured and extended LBA in the R/W helper
functions.
