xfree86: Use "Ignore" option in InputClass to skip devices
Sometimes it is desirable to skip adding specific input devices to the
server. The "Ignore" option is used similarly to Monitor sections so
that matched devices will not be added. BadIDChoice is returned to the
config backend so that it will clean up all resources.
