This patch adds core FTL (flash translation layer) submodules.
On regular SSDs the FTL is part of firmware, whereas Open Channel
enables moving it to the host and allows for having full controll
of data placement on the device.
Main functionalities added:
* logical to physical address map
* read / write buffer cache
* wear-leveling
* bad block management

reduce will be a block compression algorithm designed
specifically for SPDK. It is called "reduce" because
it reduces the data size on disk.
This patch just adds the shell of a library, include
files and unit tests. This will be fleshed out in
the rest of the patches in this series.

Currently only the iscsi => scsi dependency is defined to
demonstrate how the framework behaves.
Eventually, lib/Makefile will be populated with more lines
of the form:
DEPDIRS-iscsi : scsi log conf event
This line will ensure that the iscsi subdirectory is built
after the specified dependency directories.
Then the lib/iscsi/Makefile also defines:
DEP_LIBNAMES = scsi log conf event
This line adds dependencies from the iscsi.so to the specified
libraries.
Ideally we could avoid this duplication by passing the DEPDIRS
value to the lower level Makefile, but that breaks down when we
start considering event/subsystems/* libraries. So for now we'll
need to duplicate it. Incidentally, DPDK also duplicates the
dependency information like this.
While here, remove use of $(MAKESUBDIRFLAGS) in spdk.subdirs.mk -
it was no longer used anywhere in the tree.

Previously, lib/Makefile just hard-coded env_dpdk in the list of
directories to build; this won't work if the user has chosen a different
env implementation via CONFIG_ENV (or configure --with-env).
Modify lib/Makefile so that the user can either put their env
implementation directly into SPDK's lib directory (like env_dpdk) or
outside of the SPDK tree (in which case the user must handle building it
before building SPDK).

Exported lib/bdev/rte_virtio as a separate
library not dependent on bdev.
Virtio is now accessible via spdk_internal/virtio.h.
The header is marked `internal`, as it's
not meant to be used by end users. It's
not handy to handle all backend-specific
(e.g. Virtio-SCSI) logic in a user code.
For now the Virtio interface is publicly
exposed only via bdev_virtio module. We
might want to consider adding a separate,
public Virtio-SCSI library in the future.
Note: this patch doesn't do any changes
to the virtio code. Everything is
moved 1:1.

The NVMf target is being refactored to split the RDMA transport-specific
code into its own file. Once this is complete, we should be able to
plug in other transports and build the NVMf target without any RDMA
dependency if desired.
To enable this, change the CONFIG option to RDMA; it still controls
whether the whole NVMf target is built for now, but once the RDMA
dependency is actually made optional, we will be able to build the
generic NVMf target code without libibverbs installed.
