201c73815f Fix USB driver matching in devmatch(8).
Multiple drivers can match on the same USB device and the order of loading
decides which driver gets the device. Use the supplied mask value as an
indication of priority, so that vendor specific device drivers are loaded
before more generic ones.

3fa2c0489b Implement --hints to read hints file directly
In testing, it's often useful to copy a few files into a directory and
kldxref them to ensure that particular cases are handled correctly.
Add --hints (-h) to facilitate this testing and enable future
automated testing.

5e0195c8f5 Tweak the 'I' flagged value
'I' was omitting 'zero' values. This is not quite correct, and was put
in as a hack but not documented. Remove it. If we find what the hack
was really needed for, we'll either fix the need for it, or invent a
new flagged value type.

b9c40202d8 Implement 'T' field matching.
Implement 'T' field matching. This is needed to prevent false
positives. However, it's not general enough. It only handles one field
and there's a ton of edge cases even with that it likely wouldn't
handle. To do it more generally and also eliminate a lot of the
hackiness that's in this program now, we'd need to creating
directories for lookups ala awk, pearl, python, etc. It appears to be
sufficient, though, to get my keyboard loaded on boot.

a164a319eb Warn when we encounter unknown PNP field specifiers.
The 'T' field went unimplemented for months due to a lack of warning.
Add a warnings to detect mistakes sooner.

590682b6e6 Move devmatch to sbin from usr/sbin.
Since we want to use devmatch in context before a split /,/usr system
has mounted /usr, move devmatch to /sbin.
