Subject: iwlagn: remove un-necessary file
Most of the functions in iwl-agn-hcmd are move to other files, no point to
keep the file anymore.

Subject: iwlagn: transport layer receives struct iwl_trans*
It still holds a pointer to iwl_priv. But hopefully this will disappear at some point.
Also add the multiple inclusion protection to iwl-trans.h that was forgotten.
Move iwl-trans structures to iwl-trans.h

Subject: iwlagn: implement WoWLAN
Implement WoWLAN support in iwlagn. The device
supports a number of wakeup triggers and can do
GTK rekeying when asleep (if HW crypto is used).
Unfortunately, we need to disconnect from the AP
after resume since we can't yet get all the info
out of the wowlan uCode to stay connected safely.

Subject: iwlagn: track beacon interval sent to device
Sometimes, when mac80211 changes the beacon
interval or when it isn't yet set in mac80211
before association, the uCode will sysassert
because we send it confusing RXON timing vs.
PAN parameters. To fix this, track the last
beacon interval sent to the device and use
that in PAN parameter calculations.
This fixes a bug during P2P group formation
as a client (and possibly association to a
regular AP) while connected to another AP.
