{nl,mac,cfg}80211: Allow user to configure basic rates for mesh
Currently mesh uses mandatory rates as the default basic rates. Allow basic
rates to be configured during mesh join. Basic rates are applied only if
channel is also provided with mesh join command.

mac80211: expire mesh peers based on mesh configuration

{nl,cfg}80211: make peer link expiration time configurable
If a STA has a peer that it hasn't seen any tx activity
from for a certain length of time, the peer link is
expired. This means the inactive STA is removed from the
list of peers and that STA is not considered a peer again
unless it re-peers.  Previously, this inactivity time was
always 30 minutes.  Now, add it to the mesh configuration
and allow it to be configured.  Retain 30 minutes as a
default value.

mac80211: fix mesh deadlock
The patch "cfg80211/mac80211: use cfg80211 wdev mutex in
mac80211" introduced several deadlocks by converting the
ifmsh->mtx to wdev->mtx. Solve these by:

1. drop the cancel_work_sync() in ieee80211_stop_mesh().
   Instead make the mesh work conditional on whether the mesh
   is running or not.
2. lock the mesh work with sdata_lock() to protect beacon
   updates and prevent races with wdev->mesh_id_len or
   cfg80211.

mac80211: Use suitable semantics for beacon availability indication
Currently beacon availability upon association is marked by have_beacon
flag of assoc_data structure that becomes unavailable when association
completes. However beacon availability indication is required also after
association to inform a driver. Currently dtim_period parameter is used
for this purpose. Move have_beacon flag to another structure, persistant
throughout a interface's life cycle. Use suitable sematics for beacon
availability indication.

ieee80211_rx_bss_info() deals with dtim_period setting and PS update
when associated. Move all these to another locations cleaning this
function. Also, the current implementation is buggy because when it
calls ieee80211_recalc_ps() bss_conf->dtim_period is notset properly

cfg80211: make wiphy index start at 0 again
The change to use atomic_inc_return() for assigning the wiphy

but we all habitually type "phy0" when we're testing, so make
it go back to 0 instead of 1 by subtracting 1 from the index.

cfg80211: fix potential deadlock regression
My big locking cleanups caused a problem by registering the
rfkill instance with the RTNL held, while the callback also
acquires the RTNL. This potentially causes a deadlock since
the two locks used (rfkill mutex and RTNL) can be acquired
in two different orders. Fix this by (un)registering rfkill
without holding the RTNL. This needs to be done after the
device struct is registered, but that can also be done w/o
holding the RTNL.

cfg80211: separate internal SME implementation
The current internal SME implementation in cfg80211 is
very mixed up with the MLME handling, which has been
causing issues for a long time. There are three things
that the implementation has to provide:
 * a basic SME implementation for nl80211's connect()
   call (for drivers implementing auth/assoc, which is
   really just mac80211) and wireless extensions
 * MLME events for the userspace SME
 * SME events (connected, disconnected etc.) for all
   different SME implementation possibilities (driver,
   cfg80211 and userspace)

To achieve these goals it isn't necessary to track the
software SME's connection status outside of it's state
(which is the part that caused many issues.) Instead,
track it only in the SME data (wdev->conn) and in the
general case only track whether the wdev is connected
or not (via wdev->current_bss.)

Also separate the internal implementation to not have
callbacks from the SME events, but rather call it from
the API functions that the driver (or rather mac80211)
calls. This separates the code better.

cfg80211/mac80211: clean up cfg80211 SME APIs
Do some cleanups in the cfg80211 SME APIs, which are
only used by mac80211.

Most of these functions get a frame passed, and there
isn't really any reason to export multiple functions
as cfg80211 can check the frame type instead, do that.

Additionally, the API functions have confusing names
like cfg80211_send_...() which was meant to indicate
that it sends an event to userspace, but gets a bit
confusing when there's both TX and RX and they're not
all clearly labeled.

It also moves the documentation that was in the cw1200_sagrad source to

cw1200: Replace use of 'struct resource' with 'int' for GPIO fields.
The only advantage of 'struct resource' is that it lets us assign names

data, we are already limited to a single instance of each driver,
rendering this moot.

So, replace the struct resources with ints, resulting in cleaner code.

This was based on a suggestion from Arnd Bergmann.
