Part two of this NEWCARD update:

Briefly, the significant changes include:

• Way better resource management in pccbb, pccard and cardbus.
• pccard hot-removal now appears to work.
• support pre-fetchable memory in cardbus.
• update cardbus to support new pci bus interface functions.
• Fix CIS reading to no longer use rman_get_virtual().

What's not there, but in the works:

• pccard needs to do interrupt properly and not read the ISR on single function cards.
• real resource management for pccard
• a complete implementation of CIS parsing
• need to look into how to correctly use mutex in pccbb
