802.11 management frames supported (Was: Xmas, variadic macros, and 802.11)

Re-hi everybody,

I'm done with the support of 802.11 management frame in libnetng.
Currently, only the builders are available, not the injection.

All usual management frames are supported:
    libnet_build_802_11_mngt_auth()
    libnet_build_802_11_mngt_assoc_req()
    libnet_build_802_11_mngt_reassoc_resp()
    libnet_build_802_11_mngt_assoc_resp()
    libnet_build_802_11_mngt_reassoc_req()
    libnet_build_802_11_mngt_deauth()
    libnet_build_802_11_mngt_disassoc()
    libnet_build_802_11_mngt_probe_req()
    libnet_build_802_11_mngt_beacon()
    libnet_build_802_11_mngt_probe_resp()

See src/libnet_build_802_11.c for the builders
    include/libnet/libnet-headers.h for the data structures
    samples/80211.c for an extended example

As my family is kind of crazy, I'll have Christmas party tomorrow, so
don't expect much more before next week.
