Luis R. Rodriguez ae689390b0 cfg80211: fix parsing when db.txt ends on a rule
If genregdb.awk assumes the file will end with an
extra empty line or a comment line. This is could
not be true so just address this.

Luis R. Rodriguez af9b223551 cfg80211: add function helpers to genregdb.awk
This has no functional change, this just lets us reuse
helpers at a later time.

Luis R. Rodriguez 8fe02e167e cfg80211: consolidate passive-scan and no-ibss flags
These two flags are used for the same purpose, just
combine them into a no-ir flag to annotate no initiating
radiation is allowed.

Old userspace sending either flag will have it treated as
the no-ir flag. To be considerate to older userspace we
also send both the no-ir flag and the old no-ibss flags.
Newer userspace will have to be aware of older kernels.

Update all places in the tree using these flags with the
following semantic patch:

remove duplicates and to fix some indentation.

Janusz Dziedzic f0823475d5 cfg80211: parse dfs region for internal regdb option
Add support for parsing and setting the dfs region (ETSI, FCC, JP)
when the internal regulatory database is used. Before this
the DFS region was being ignored even if present on the used
db.txt

Luis R. Rodriguez 3b77d5ec0c cfg80211: relicense reg.c reg.h and genregdb.awk to ISC
Following the tradition we have had with ath5k, ath9k, CRDA,
wireless-regdb I'd like to license this code under the permissive ISC
license for the code sharing purposes with other OSes, it'd sure be nice
to help the landscape in this area. Although I am %82.89 owner of the
regulatory code I have asked every contributor to the regulatory code
and have receieved positive Acked-bys from everyone except two deceased
entities:

 o Frans Pop RIP 2010 [0]
	- Frans Pop <elendil@planet.nl>
	- Frans Pop <fjp@debian.org>
 o Nokia     RIP February, 11, 2011 [1], [2]
	- ext-yuri.ershov@nokia.com
	- kalle.valo@nokia.com

Frans Pop's contribution was a simple patch 55f98938, titled,
"wireless: remove trailing space in messages" which just add a \n
to some printk lines. I'm going to treat these additions as
uncopyrightable.

As for the contributions made by employees on behalf of Nokia
my contact point was Petri Karhula <petri.karhula@nokia.com> but
after one month he noted he had not been able to get traction from the
legal department on this request, as such it I proceeded by replacing
their contributions in previous patches.

The end goal is to help a clean rewrite that starts in userspace
that is shared under ISC license which currently is taking place with
the regulatory simulator [3].

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).
