Currently when mac80211 asks to change the interface
type, we will accept it for both the BSS and PAN
contexts. This is not terribly complicated today,
but with the addition of the P2P Device abstraction
the PAN context handling will get more complex, so
restrict mac_change_interface to the BSS context.

Also fix a small locking issue and use is_active
instead of the vif pointer to check if the other
context is activated, guarding exclusive interface
types on the BSS context (IBSS) against the PAN
context being used for something else.

When the first interface is active, then scanning
on it or the second interface can take a little
longer than 7s (I observed around 8s.) Bump the
timeout to 15s to avoid aborting a scan that is
still running, just taking more time.

My previous commit to shorten the radio reset time
caused issues as the firmware checks the active
dwell time against the quiet time, asserting that
the dwell is >= quiet time. This isn't really
needed in case of passive scanning like here, but
of course we need to pass that check.

To fix this, override the quiet time to be the
same as the radio reset dwell time.

The effect of using a short single-channel scan
to reset the radio is that scanning a channel
that isn't in use needs to re-tune the radio.
This means that the dwell time is irrelevant,
so use a shorter time.

While at it, clean up the code for this a bit.

When the device is doing an internal radio reset
scan, ROC can be rejected to the supplicant with
busy status which confuses it.

One option would be to queue the ROC and handle
it later, but since the radio reset scan is very
quick we can just wait for it to finish instead.

Also add a warning since we shouldn't run into
the case of having a scan active when requesting
a ROC in any other case since mac80211 will not
scan while ROC or ROC while scanning.

The iwl-test flows were based on the cfg80211 testmode APIs.

To remove this coupling, the op mode (during the initialization
of the iwl_test object) is responsible to set the callbacks that
should be used by iwl-test to allocate skbs for events and replies
and to send events and replies.

The current op modes implement these callbacks based on the cfg80211
testmode APIs.

The EEPROM reading/parsing code is all mixed in
the driver today, and the EEPROM is parsed only
when we access data from it. This is problematic
because the NVM needs to be parsed and that is
independent of reading it. Also, the NVM format
for new devices will be different and probably
require a new parser.

Therefore refactor the reading and parsing and
create two independent components. Reading the
EEPROM requires direct hardware accesses and
therefore access to the transport, but parsing
is independent and can be done on an NVM blob.
