Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

New spdk_ftl_conf parameter l2p_path, l2p_path defines
location of existing pmem file or device to use as l2p table.
ftl_dev_l2p_alloc now has two flows:
1. If l2p_path is set perform pmem_map_file (PMDK) of l2p_size on it
2. Else malloc l2p table as usual
l2p_get/set will use atomic_load/store on both of those storage
locations as PMDK pmem_memcpy family of functions is not thread safe.

This patch adds the ftl_batch strucutre, which describes a single batch
of data to be written to the disk. It's comprised of multiple write
buffer entries (the actual number depends on the write unit size of the
underyling device).
Additionally, a function responsible for filling out a batch was added.
It iterates over available IO channels and dequeues submitted write
buffer entries until a batch is completed. The IO channel queue is
shifted, so that each time the function is called a subsequent IO
channel is used first, which guarantees that all channels are treated
fairly.

This is the first patch of a series that replaces single global write
buffer with per-io_channel buffers. This change is intended to improve
performance for multithreaded workloads.
This patch changes the way the ftl_io_channels are allocated by only
keeping an ftl_io_channel pointer inside spdk_io_channel's context. It
allows for delaying IO channel destruction, which in turn allows the FTL
to iterate over all exisiting IO channels without locking.

Track the band under defrag inside the reloc module. This allows for
multiple bands being defragged at the same time (e.g. extra one due to
write fault) as well as makes it easier to handle cases when relocating
a band that has no valid blocks.

Changed initialization of io channels to be made in the core/read
thread themselves. This fixes potential hangs when using the ftl lib
