Johannes Berg 90a53e4432 cfg80211: implement regdb signature checking
Currently CRDA implements the signature checking, and the previous
commits added the ability to load the whole regulatory database
into the kernel.

However, we really can't lose the signature checking, so implement
it in the kernel by loading a detached signature (regulatory.db.p7s)
and check it against built-in keys.

Johannes Berg c8c240e284 cfg80211: reg: remove support for built-in regdb
Parsing and building C structures from a regdb is no longer needed
since the "firmware" file (regulatory.db) can be linked into the
kernel image to achieve the same effect.

John W. Linville 3b377ea9d4 wireless: support internal statically compiled regulatory database
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).
