The array of rmc_entrys is redundant since only the
list_head is used. Make this an array of list_heads
instead and save ~6k per vif at runtime :D

Convert mac80211 (and where necessary, some drivers a
little bit) to the new channel definition struct.

This will allow extending mac80211 for VHT, which is
currently restricted to channel contexts since there
are no drivers using that which makes it easier. As
I also don't care about VHT for drivers not using the
channel context API, I won't convert the previous API
to VHT support.

Before, a mesh STA would execute some code on behalf of AP or IBSS
beacons. Since the mesh stack currently does not consider anything but
other mesh STAs interesting, limit processing to just these and save a
little overhead.

estab_plinks is not a statistics member. Hence move estab_plinks from
struct mesh_stat to struct ieee80211_if_mesh

Instead of operating on a single channel only,
use the new channel context infrastructure in
all mac80211 code.

This enables drivers that want to use the new
channel context infrastructure to use multiple
channels, while nothing should change for all
the other drivers that don't support it.

Right now this disables both TX power settings
and spatial multiplexing powersave. Both need
to be re-enabled on a channel context basis.

Additionally, when channel contexts are used
drop the connection when channel switch is
received rather than trying to handle it. This
will have to be improved later.

Using local->_oper_channel_type in the mesh code is
completely wrong as this value is the combination
of the various interface channel types and can be
a different value from the mesh interface in case
there are multiple virtual interfaces.

Use sdata->vif.bss_conf.channel_type instead as it
tracks the per-vif channel type.
