If change_interface gets invoked during a firmware
restart, it may crash; prevent that from happening
by checking if ctx->vif is assigned.

Additionally, in my initial commit I forgot to set
the vif->p2p variable correctly, so fix that too.

The microcode may sometimes reject TX frames when
on a radar channel even after we associated as it
clears information during association and needs to
receive a new beacon before allowing that channel
again. This manifests itself as a TX status value
of TX_STATUS_FAIL_PASSIVE_NO_RX. So in this case,
stop the corresponding queue and give the frame
back to mac80211 for retransmission. We start the
queue again when a beacon from the AP is received
which will make the regulatory enforcement in the
device allow transmitting again.

We have no other option but to inform userspace that we
have queued up their regulatory hint request when we are
given one given that nl80211 operates atomically on user
requests. The best we can do is accept the request, and
add a delayed work item for processing failure and cancel it
if we succeeed. Upon failure we restore the regulatory
settings and ignore the user input.

This fixes this reported bug:

When we restore regulatory settings its possible CRDA
will not reply because of a bogus user entry. In this
case the bogus entry will prevent any further processing
on cfg80211 for regulatory domains even if we restore
regulatory settings.

To prevent this we suck out all pending requests when
restoring regulatory settings and add them back into the
queue after we have queued up the reset work.

The impact of not having this applied is that a user
with privileges can issue a userspace regulatory hint
while we are disasocciating and this would prevent any
further processing of regulatory domains.

This generates a massive reduction in module size:
with debug:
   text	   data	    bss	    dec	    hex	filename
 670300	  13136	    420	 683856	  a6f50	iwlagn.ko (before)
 388347	  13136	    408	 401891	  621e3	iwlagn.ko (after)

without debug:
   text	   data	    bss	    dec	    hex	filename
 528575	  13072	    420	 542067	  84573	iwlagn.ko (before)
 294192	  13072	    408	 307672	  4b1d8	iwlagn.ko (after)

This also removes all the IO debug functionality since
it can easily be replaced by tracing, and makes the
code unnecessarily complex.

I haven't done any CPU utilisation measurements, but
given that the hotpaths don't use much IO it is not
likely to have a negative impact; in fact, the size
reduction will reduce cache pressure which possibly
improves performance.

Finally, an unused function or two were removed.

Devices newer than 4965 don't actually send
two different versions of the ALIVE command,
so we always had a bug here since before this
patch we copy more data than we got. Remove
the iwl_init_alive_resp struct and don't use
it.

Since we also really don't need to track all
the data received in ALIVE as we only use the
error and log event tables later, we can also
save space by just keeping those and not more
data around in memory.

Some new devices and microcode files will a greater
variety of features, so the TLV-per-feature approach
we took before will quickly make things harder to
manage and increase the file size.

Add a new TLV that has feature flags. Currently, it
will contain:
 1) a PAN feature flag, which moves from a separate
    TLV
 2) a new BT stats bit that indicates whether the
    microcode image uses bluetooth statistics
 3) a new MFP flag for management frame protection
    which can be enabled once the device/microcode
    supports it

The ucode restart has to take into account a number
of things, like clearing the HCMD_ACTIVE and other
status bits, and waking up the wait_command_queue.
Currently, however, there are a number of places
that neither do that, nor actually set the FW error
bit that leads to proper restart handling, which
means that in those cases things will probably just
hang completely.

To clean this up, make all ucode restart go through
a single function, except for the cases where it's
called during firmware loading.

Also fix a bug in wimax coexist restart avoidance,
it needs to first clear the status bits (and it has
to clear the HCMD_ACTIVE one as well) and then wake
up anything waiting on wait_command_queue.
