[Feature request] KeyHandler shell script/binary executed at each remote control key press

[xeros]

I would like to get /bin/keyhandler or something simmilar being executed with system() call with key hex code as argument from libopenrelease.so on each button press.
Such thing can be enabled/disabled (disabled by default) in openrelease.cfg option.
For example:
keyhandler = /bin/keyhandler
with default:
keyhandler = NULL

So it would run for example '/bin/keyhandler a9' for Guide button press.

Such code should wait until /bin/keyhandler exits (some timeout?), check its exit status and depends on exit status run other key events actions or not.

Examples of exit status:
0 - key action has been run, stop doing other actions.
1 - generate just uinput event
2 - run action set in openrelease_keymap.cfg
3 - generate uinput event and run action set in openrelease_keymap.cfg
... ?

We could then enhance functionality with such script or binary to execute actions in Linux shell depends on which key has been pressed.
