xfree86: Match devices based on PnP ID

Serial input devices lack properties such as product or vendor name. This
makes matching InputClass sections difficult. Add a MatchPnPID entry to
test against the PnP ID of the device. The entry supports a shell pattern
match on platforms that support fnmatch(3). For example:

	MatchPnPID "WACf*"

A match type for non-path pattern matching, match_pattern, has been added.
The difference between this and match_path_pattern is the FNM_PATHNAME
flag in fnmatch(3).
