debugging macros.

Patch #4:
Virtual access point code. It is based on a message queue and a timer that
repeatedly injects the ingoing messages and replies into the queue. Outgoing
messages are parsed to extract the IP-datagram from the wireless packet and
passed on to Qemu.
There are 3 important functions
Patch #5:
The most important/difficult/ugly part: Hardware I/O. It is handled over a
direclty
mapped memory regions that is written to/read from the device driver code. Based
on ath5k and plenty of reverse engineering.
NOTE: I did NOT reimplement the hardware!! I simply handled the events as
Patch #6:
802.11 packet definitions. Code to create beacon frames, probe responses,
authentication frames, association replies, etc.

Patch #8:
CRC32 helper code. Sorry if there is already some global function that could
be used for this purpose. Simply took the code from Wireshark (license and
header documentation unchanged obviously).
