libusb: hotplug, use events instead of a timer when possible

Try to fetch events from nlsysevent or devd to determine when
to scan the usb bus for devices addition or removal.
if none are available fallback on the regular timer based (4s)
scanner

if devd socket or netlink socket is closed or error fallback on the
timer based method.

libusb(3): Ignore SIGPIPE when initializing the LibUSB v1.0 API.

The LibUSB v1.0 emulation layer uses pipes internally to signal between
threads. When USB devices are reset, as part of loading firmware, SIGPIPE
may happen, and that is expected and should be ignored.

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

Specifically, add LIBUSB_CLASS_PHYSICAL and the libusb_has_capability API.
Descriptions and functionality for these derived from the
documentation at [0]. The current set of capabilities are all supported by
libusb.

These were detected as missing after updating net/freerdp to 2.1.1, which
attempted to use both.

libusb: LIBUSB_DEBUG environment variable override of libusb_set_debug

The debug level generally just controls verbosity of libusb for debugging
libusb devices/usage. We allow the environment to set the debug level
independent of the application, but the application will always override
this if it explicitly sets the debug level.

Changing the environment is easy, but patching the software to change the
debug level isn't necessarily easy or possible. Further, there's this
write-only debug_fixed variable that would seem to imply that the debug
level should be fixed, but it isn't currently used. Change the logic to use
strtol() so we can detect real 0 vs. conversion failure, then honor
debug_fixed in libusb_set_debug.

Fix issues about cancelling USB transfers in LibUSB when the USB device has
been detached. When a USB device has been detached the kernel file handle
stops responding to commands. USB applications which continue to run after
the USB device has been detached, depend on LibUSB generated events to tear
down its pending USB transfers. Add code to handle the needed cleanup when
processing the USB transfer(s) fails and prevent new USB transfer(s) from
being submitted.

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.
