Virgin import of Xircom PCCARD driver v1.14

This driver is mostly based on the `xirc2ps' driver for Linux by Werner
Koch. Werner has even allowed his code to be distributed under a BSD licence,
making our life considerably easier -- thanks Werner!

This driver supports:

• Intel EtherExpress(TM) PRO/100 PCCARD (16-bit version)
• Xircom CreditCard CE2 / CEM28 / CEM33 / CE3 / CEM56 Ethernet adapters.
• Toshiba Advanced Network 10/100 PCCARD
• Certain Compaq Netelligent 10/100 branded cards

v1.14 has major changes to media selection code, and bugfixes in the
probe routine.
