xfree86: Match devices based on USB ID

Browse Source 
Sometimes the vendor and product names aren't specific enough to target
a USB device, so expose the numeric codes in the ID. A MatchUSBID entry
has been added that supports shell pattern matching when fnmatch(3) is
available. For example:

	MatchUSBID "046d:*"

The IDs are stored in lowercase hex separated by a ':' like "lsusb" or
"lspci -n".
