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.

This adds parsing of QCA vendor specific elements and as the first such
element to be parsed, stores pointers to the preferred frequency list
element that can be used to enhance P2P channel negotiation behavior.

The cwmin/cwmax parameters were limited more than is needed. Allow the

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

GO when those channels are allowed for AP mode in the current regulatory
domain.

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

need to keep the code here either, so save couple of bytes here.
