cfg80211: advertise extended capabilities to userspace

In many cases, userspace may need to know which of the
802.11 extended capabilities ("Extended Capabilities
element") are implemented in the driver or device, to
include them e.g. in beacons, assoc request/response
or other frames. Add a new nl80211 attribute to hold
the extended capabilities bitmap for this.

cfg80211: add flags to define country IE processing rules

802.11 cards may have different country IE parsing behavioural
preferences and vendors may want to support these. These preferences
were managed by the WIPHY_FLAG_CUSTOM_REGULATORY, the
WIPHY_FLAG_STRICT_REGULATORY flag and their combination.
Instead of using this existing notation, split out the country IE
behavioural preferences to a new flag. This will allow us to add more
customizations easily and make the code more maintainable.Also add
a new flag to disable country IE hints issued by the CORE, this
will allow the users to disable 802.11d support.

cfg80211: add cellular base station regulatory hint support

Cellular base stations can provide hints to cfg80211 about
where they think we are. This can be done for example on
a cell phone. To enable these hints we simply allow them
through as user regulatory hints but we allow userspace
to clasify the hint as either coming directly from the
user or coming from a cellular base station. This option
is only available when you enable
CONFIG_CFG80211_CERTIFICATION_ONUS.

The base station hints themselves will not be processed
by the core unless at least one device on the system
supports this feature.

regulatory: don't write past array when intersecting rules

When intersecting rules, we count first to know how many
rules need to be allocated, and then do the intersection
into the allocated array. However, the code doing this
writes past the end of the array because it attempts to
do all intersections. Make it stop when the right number
of rules has been reached.

regulatory: don't allocate too much memory

There's no need to allocate one reg rule more
than will be used, reduce the allocations. The
allocation in nl80211 already doesn't allocate
too much space.

regulatory: clean up regdom_intersect

As the dummy_rule (also renamed from irule) is only
used for output by the reg_rules_intersect() function
there's no need to clear it at all, remove that.

regulatory: simplify freq_reg_info_regd

The function itself has dual-purpose: it can
retrieve from a given regdomain or from the
globally installed one. Change it to have a
single purpose only: to look up from a given
regdomain. Pass the correct regdomain in the
freq_reg_info() function instead.

This also changes the locking rules for it,
no locking is required any more.
