Add in all the variables set in the kenv variable devmatch_blocklist
too. This allows blocking autoloading from the boot loader.

When matching entries, we should ignore those with a name of '#'. It's
the standard way to skip elements and need to be present to have the
proper offsets to the fields that are observed. No bus has a pnp
attribute of '#' and that is now disallowed for future buses that are
written.

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.

In the conversion, the newline got stripped. It worked fine when there
was only one module, but not when there are many. Add back the missing
newline.

up the device described by the nomatch event in the device tree. If we
find it, then if the device is marked as have already attached to a
device once, then ignore the device.
This keeps us from reloading the device driver when it has just been
manually unloaded. All devies that have had a driver attach to them at
least once no longer participate in pnp-based autoloading.

This flag is set once the device has been successfully attached. When
set, it inhibits devmatch from trying to match the device. This in
turn allows kldunload to work as expected. Prior to the change, the
driver would immediately reload because devmatch had no notion that
the driver had once been attached, and therefore shouldn't participate
in further matching.

This backs out the hack we added in r329458. Now that we can freeze /
thaw probing, this is a much better solution to that problem. Revert
to simply printing the results as we find them, and relying on an
external sort | uniq to clean up the list.

Continuing with a NULL hints variable just triggers a segfault later on.
The other error cases in this function all exit for an error rather than

Despite best efforts to regularize, there's a few tables in the system
that still report they are for bus usb when they are really for bus
uhub (where usb devices attach). Add a temporary workaround for this
until these places have been eliminated (likely my fault).
Second, when running verbose, describe what we're doing when
searching. This output can be quite long, but says exactly what's
going on (this output is to stdout, so it's useless for scripting).
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.

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.

'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.

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.
