Add definitions for global operating classes. These definitions will be
used to construct supported operating classes information element.
The operating classes definitions used locally for P2P module will be
removed and included in the general operating classes definitions.

Reorder terms in a way that no invalid pointers are generated with
pos+len operations. end-pos is always defined (with a valid pos pointer)
while pos+len could end up pointing beyond the end pointer which would
be undefined behavior.

CA country code was included mistakenly (copy-paste..) in cn_op_class_cc
while it was supposed to be included only in us_op_class_cc. In
practice, this did not result in incorrect operation due to the
us_op_class_cc list being checked first. Anyway, better fix
cn_op_class_cc to avoid confusion here.

Add operating class 125 (channels 149..169) to the list of P2P supported

All the existing users of these elements were already validating the
element length. However, it is clearer to validate this already at the
parser for extra layer of protection for any future changes.

The SSID element is defined to have a valid length range of 0-32. While
this length was supposed to validated by the users of the element
parser, there are not really any valid cases where the maximum length of
32 octet SSID would be exceeded and as such, the parser itself can
enforce the limit as an additional protection.

This allows vendor specific information element to be used to advertise
support for VHT on 2.4 GHz band. In practice, this is used to enable use
of 256 QAM rates (VHT-MCS 8 and 9) on 2.4 GHz band.
This functionality is disabled by default, but can be enabled with
vendor_vht=1 parameter in hostapd.conf if the driver advertises support
for VHT on either 2.4 or 5 GHz bands.

ieee80211_chan_to_freq() is a generic function that replaces and extends

These information elements are not really used anywhere in hostapd or

Some frequent debug prints are of limited use and make debug output
difficult to read. Make them use a new debug level so that -dd
provides more readable output (-ddd can now be used to enable
the excessive debug prints).
This adds first part of FT resource request as part of Reassocition
Request frame (i.e., FT Protocol, not FT Resource Request Protocol).
wpa_supplicant can generate a test resource request when driver_test.c
is used with internal MLME code and hostapd can verify the FTIE MIC
properly with the included RIC Request.
The actual RIC Request IEs are not processed yet and hostapd does not
yet reply with RIC Response (nor would wpa_supplicant be able to
validate the FTIE MIC for a frame with RIC Response).
