This patch unifies the namespace of variables, functions defines
and structures. It does:

- rename libertas_XXX to lbs_XXX
- rename LIBERTAS_XXX to lbs_XXX
- rename wlan_XXX to lbs_XXX
- rename WLAN_XXX to LBS_XXX (but only those that were
  defined in libertas-local *.h files, e.g. not defines
  from net/ieee80211.h)

While passing, I fixed some checkpatch.pl errors too.

Previously if a fixed channel was specified along with an SSID,
the channel request would be ignored during the association
process.  Instead, when searching for an adhoc or infrastructure
network to join, allow filtering results based on channel so
that the driver doesn't pick a BSS on a different channel than
requested.

The BSS to associate with (in either Infrastructure or IBSS join
operations) is now stored in _one_ place in the association request (the
bss member), not two places as before (pattemptedbss and
curbssparams->bssdescriptor).

Association requests are passed to the necessary association functions
to (a) give them access to the bss member and (b) ensure that
association/join/start setup uses settings from the request, not the
current adapter settings (which may not be valid for the requested
settings).

Because the 'bss' member of the association request is used now, the
command return functions from associate and adhoc join/start need access
to the in-progress association request to update curbssparams when
everything is done.  The association worker moves the request from
pending to in-progress for the duration of the association attempt.
