libusb: remove use of COMPAT_32BIT

This codepath used uint64_t's in place of pointers in structs and
arrays to allow 32-bit code to use 64-bit version of ioctls. Now
that we support 32-bit compat natively this is no longer needed.

Improve handling of USB device re-open in the LibUSB v1.x API.

Make sure the "device_is_gone" flag is cleared after every successful open,
so that the "device_is_gone" flag doesn't persist forever.

lib: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Fix array size issue when using the pre-scaling feature for
ISOCHRONOUS USB transfers. Make sure enough length and buffer pointers
are allocated when setting up the libusb transfer structure to support
the maximum number of frames the kernel can handle.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Resort includes to match style(9) a bit more. No functional change
is expected after this commit.
