488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
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.

There is no change in functionality with this patch, just movement

Also note that some flags in scenarios that we know are required are
still set by the library.

d1df8a1617 idxd: don't limit number of completions per poll
This limitation doesn't really take effect currently,
since the typical number of slots per channel isn't
bigger than MAX_COMPLETIONS_PER_POLL.  But there's
no reason for this limit anymore - we should always
poll as many completions as we find.

It's better to remove this now, in case we have
configs in the future with higher number of slots
per channel.
