    This is a partial revert of aa03004ace2fabb135a6208ef8c2d2b312aa7b0b. The
    approach that was taken leads to disagreement and the change was pushed
    too early. DISTRO_PR is going to say and will be used inside the package
    creation. There will be more disucssion on the list about where to continue
    from here.

    Allow a distribution to globally bump the PR of every package
    this is useful when there was a change in the toolchain and
    every package is going to be different.

    find packages/ \( -name '*.bb' -or -name '*.inc' \) -exec sed -i s/"^PR="/"FILE_PR ="/ {} \;
    find packages/ \( -name '*.bb' -or -name '*.inc' \) -exec sed -i s/"^PR ="/"FILE_PR ="/ {} \;

* We of course still want to receive key events even after subscribing to 
property events. This fixes when keylaunch doesn't receive forwarded 
power buttons events from gpe-login --autolock in its locked state. 
In plain words: now power button works with autolock screen. 

* It is possible to unambigously distingish events only of two types:
<default> (short press) and "Held" (long press). Using any other event
type is ambigous. In particular, with the old default config there was
ambiguity with power off and backlight toggle bindings - most of the time,
backlight toggling also caused power off. As freedom of using any key in any
way should be left to user, ambigouos bindings should be avoided.

from random crap aka device-specific (mis)configs and hacks.
