This module simply sits on another virtual bdev

FTL doesn't have any kind of special package requirements.
It is getting pretty good traction in the community, so
let's enable it by default.
Note that we will disable FTL on FreeBSD. FTL uses
CIRCLEQ which is not available on FreeBSD. Let's not
spend time trying to get FTL to work on FreeBSD until
there's a demand to do so.

Add OCF module based on OCF meta-library
Open CAS Framwework (OCF) is high performance block storage
caching meta-library
It is open-source, published at https://github.com/Open-CAS/ocf
With this patch OCF-enabled device is represented in SPDK
as virtual bdev having core and caching devices as its base devices
This patch includes implementation of:
* OCF top adapter (vbdev_ocf.c)
* OCF bottom adapter (dobj.c, data.c)
* Adaptation layer for OCF (env/)
* OCF context abstractions (ctx.c)
Adaptation layer and context abstractions are not dependent on SPDK bdev
OCF bdev supports reads and writes, configured at startup
Other features will be added with separate patches

dependencies in mk/spdk.modules.mk. This patch adds blobfs there

These changes are needed for some upcoming patches which will
apply --whole-archive to all libraries linked into the application.
That patch will require that we never include the same library
twice.
Shared library builds *require* that blobfs be listed before
blob on the link line, hence adding blobfs here even though it's
not technically associated with a bdev module.
We can also simplify spdk.modules.mk while we're here - just
filter out bdev_lvol to disable lvol for applications like
blob_cli that need to disable it.

QAT can be included in the code (but not makefile) and marked as experimental
until we are ready to test in CI. It works well on 2 systems but is a big PITA to get

Raid module:
============
- SPDK raid bdev module is a new bdev module which is
responsible for striping various NVMe devices and expose the raid bdev
to bdev layer which would enhance the performance and capacity.
- It can support theoretically 256 base devices (currently it is being
tested max upto 8 base devices)
- Multiple strip sizes like 32KB, 64KB, 128KB, 256KB, 512KB etc is
supported. Most of the current testing is focused on 64KB strip size.
- New RPC commands like "create raid bdev", "destroy raid bdev" and "get raid bdevs"
are introduced to configure raid bdev dynamically in a running
SPDK system.
- Currently raid bdev configuration parameters are persisted in the
current SPDK configuration file for across reboot support. DDF will be
introduced later.
High level testing done:
=======================
- Raid bdev is created with 8 base NVMe devices via configuration
file and is exposed to initiator via existing methods. Initiator is
able to see a single NVMe namespace with capacity equal to sum of the
minimum capacities of 8 devices. Initiator was able to run raw
read/write workload, file system workload etc (tested with XFS file
system workload).
- Multiple raid bdevs are also created and exposed to initiator and
tested with file system and other workloads for read/write IO.
- LVS / LVOL are created over raid bdev and exposed to initiator.
Testing was done for raw read/write workloads and XFS file system
workloads.
- RPC testing is done where on the running SPDK system raid bdevs
are created out of NVMe base devices. These raid bdevs (and LVOLs
over raid bdevs) are then exposed to initiator and IO workload was
tested for raw read/write and XFS file system workload.
- RPC testing is done for delete raid bdevs where all raid bdevs
are deleted in running SPDK system.
- RPC testing is done for get raid bdevs where existing list of
raid bdev names is printed (it can be all raid bdevs or only
online or only configuring or only offline).
- RPC testing is done where raid bdevs and underlying NVMe devices
relationship was returned in JSON RPC commands
