[PATCH 0/4] hostapd: add ACS support

[Luis R. Rodriguez]

This series adds ACS support to hostapd. I've completed
a few of my own TODOs and splitted up the patches as
best as possible. I'm pretty satisfied with this code now
as an initial start for ACS code. At this point we need
to start finding ideal values for the metrics for offchannel
operation so that we can consistently always find the same
channel, even if it means surveying longer or doing more
scans.

Other algorithms for ACS shoudl be easy to plug in, for example,
spectral scan ;)

Anyway, to enable and test this thing just set CONFIG_ACS=1
on your build config and then something like this on your
hostapd.conf:

channel=acs_survey
acs_num_req_surveys=10
acs_roc_duration_ms=100

Test results, rants are appreciated.
