FSF addresses used in PA sources are no longer valid and rpmlint
generates numerous warnings during packaging because of this.
This patch changes all FSF addresses to FSF web page according to
the GPL how-to: https://www.gnu.org/licenses/gpl-howto.en.html
Done automatically by sed-ing through sources.
This adds module-hal-detect-compat.c which when enabled will be compiled
into a module module-hal-detect which simply loads module-udev-detect.
The purpose of this is to allow easy upgrading without breaking
default.pa. Distributions are recommended to enable this to easy
upgrades from HAL versions of PA to udev versions.
