mpsutil: Clean up libutil deps

mpsutil doesn't use libutil, so doesn't need to include libutil.h. See
commit 76103694a051335bec1da318f9c6e3a676dc0145.

No functional change intended.

mpsutil: Fix data truncation by too short buffers.

Length of some string buffers was insufficient for cases of more that
99 targets per HBA or slots per enclosure. Some others are tuned just
for better alignment. While there also fix output formatting issues.

mpsutil: extend show adapter information, add NCQ control

'show adapter' now shows PCIe width and speed, IOC Speed, and the
temperature of the controller.

A new command, 'set ncq', is added.
It enables or disables SATA NCQ in the NVRAM of the card.
Its current setting is added to 'show adapter' as well.

Differential Revision: https://reviews.freebsd.org/D26040

Add support for some IOCFacts fields that are available with mpr (12Gb)
controllers. It's ugly due to the single codebase for mpr and mps and
not being able to share their respective headers.

Touch up some of the iocfacts fields

Regularize the Netflix copyright

Use recent best practices for Copyright form at the top of
the license:
1. Remove all the All Rights Reserved clauses on our stuff. Where we
piggybacked others, use a separate line to make things clear.
2. Use "Netflix, Inc." everywhere.
3. Use a single line for the copyright for grep friendliness.
4. Use date ranges in all places for our stuff.

Approved by: Netflix Legal (who gave me the form), adrian@ (pmc files)

Add a new 'debug' command tree and 'dump_reqs' command to grab and parse
command and chain frames of in-flight I/O from the driver.
