This patch provides infrastructure for machine translation of the
regulatory rules database used by CRDA into a C data structure.
It includes code for searching that database as an alternative
to dynamic regulatory rules updates via CRDA. Most people should
use CRDA instead of this infrastructure, but it provides a better
alternative than the WIRELESS_OLD_REGULATORY infrastructure (which
can now be removed).

The payload alignment warning enabled by MAC80211_DEBUG_PACKET_ALIGNMENT is
difficult. To fix it, a firmware change is needed but in most cases that's
very difficult. So the benefit from the warning is low and most probably
it just creates more confusion for people who just enable all warnings
(like it did for me).
Remove the unaligned IP payload warning and the kconfig option. But
leave the unaligned packet warning, it will be enabled with
MAC80211_VERBOSE_DEBUG.

For bluetooth 3, we will most likely not have
a netdev for a virtual interface (sdata), so
prepare for that by reducing the reliance on
having a netdev. This patch moves the name
and address fields into the sdata struct and
uses them from there all over. Some work is
needed to keep them sync'ed, but that's not
a lot of work and in slow paths anyway.
In doing so, this also reduces the number of
pointer dereferences in many places, because
of things like sdata->dev->dev_addr becoming
sdata->vif.addr.

The station management currently uses the virtual
interface, but you cannot add the same station to
multiple virtual interfaces if you're communicating
with it in multiple ways.
This restriction should be lifted so that in the
future we can, for instance, support bluetooth 3
with an access point that mac80211 is already
associated to.
We can do that by requiring all sta_info_get users
to provide the virtual interface and making the RX
code aware that an address may match more than one
station struct. Thanks to the previous patches this
one isn't all that large and except for the RX and
TX status paths changes has low complexity.

BugLink: https://bugs.launchpad.net/ubuntu/+bug/254837
Spurious shared interrupts or early probing interrupts can cause the
hostap interrupt handler to oops before the driver has fully configured
the IO base port addresses. In some cases the oops can be because
the hardware shares an interrupt line, on other cases it is due to a
race condition between probing for the hardware and configuring
the IO base port. The latter occurs because the probing is required to
determin the hardware port address which is only determined when the probe
can interrupt the hardware (catch 22).
This patch catches this pre-configured condition to avoid the oops.

the nl80211 code to cfg80211 where it is now shared between both the
nl80211 interface and the wireless extensions interface.

Sergei Shtylyov notes "You call min() on uncomparables [in
mwdma_clip_to_pio()], i.e. mwdma_to_pio[] contains XFER_PIO_* and
adev->pio_mode - XFER_PIO_0 yields you a mode number. Thus the second
argument will always "win" as a minimal one"
Bartlomiej Zolnierkiewicz adds "There are more issues with the patch related
to mwdma_clip_to_pio(). The function can return values between 0 and
4 which obviously won't work well for the new code below for values
>2 (i.e. resulting in out-of-bounds array access for the common-case
of dev->pio_mode == XFER_PIO_4)."
