Save frequency to network config

Also save frequency in wpa_config_write_network().

This is necessary for creating IBSS networks which requires the
frequency to be set.

Add capability flag for IBSS and get_capabiliy modes

Add a driver capability flag for drivers which support IBSS mode and
set it for nl80211 drivers which have set the NL80211_IFTYPE_ADHOC.

Add a new option "modes" to "get_capability" which will return
"AP" and "IBSS" if the corresponding capability flags are set.

wpa_supplicant: Add get_capability freq

Add "get_capability freq" command to print a more verbose list of channels and
frequencies in MHz. The tag "NO_IBSS" is added, if IBSS mode is not allowed on
a channel. This allows userspace programs to get the frequencies and
limitations associated with each channel.

This extends the information already provided in "get_capability channel" but a
new interface is chosen because of backwards compatibility considerations.
