cfg80211: pass station supported channel and oper class info

The information of the peer's supported channels and supported operating
classes are required for the driver to perform TDLS off channel
operations. This commit enhances the function nl80211_(new)set_station
to pass this information of the peer to the driver.

nl80211: vendor command support

Add support for vendor-specific commands to nl80211. This is
intended to be used for really vendor-specific functionality
that can't be implemented in a generic fashion for any reason.
It's *NOT* intended to be used for any normal/generic feature
or any optimisations that could be implemented across drivers.
Currently, only vendor commands (with replies) are supported,
no dump operations or vendor-specific notifications.
Also add a function wdev_to_ieee80211_vif() to mac80211 which
is needed for mac80211-based drivers wanting to implement any
vendor commands.

nl80211: support vendor-specific events

In addition to vendor-specific commands, also support vendor-specific
events. These must be registered with cfg80211 before they can be used.
They're also advertised in nl80211 in the wiphy information so that
userspace knows can be expected. The events themselves are sent on a
new multicast group called "vendor".
