Description
This is a client function for messaging piboxd. That means the type, action and subaction definitions need to move into libpibox too.

piboxMsg() is now in libpibox but picam is still using piboxMsgSend() in it's utils.c module. I need to check that the latter can be replaced with the former, then make sure all message types are supported in the library function.

The piboxlib version of the function is not as full featured as the picam version. So the former needs updating. But I wasn't sure who else was using it. Turns out no one is using it except PiCam. So I can update the library to the PiCam version and test that, then update a Dev platform with the new library, builds all the apps and make sure they all still work.
To verify that no one else is using it I just grep'd for piboxMsg in every app that I wrote that doesn't wrap some 3rd party software. Looks like only PiCam is using this function. So I THINK I'm safe in doing this.
Ran the following command from the top of my source trees:
find pi* appmgr iotapp ironman launcher libpibox musicfe pnc videofe xeonnc -type f -name "*.c" -exec grep -li piboxmsg {} \;It generated this list

- pitemplate: a copy of picam
- pixm: an unused utility function that should be removed
- iotapp: also needs updating, like picam
- libpibox: library function picam and iotapp will use, plus unit tests
- xeonnc: also needs updating, like picam

piboxlib is ported and basically passes unit tests. I need to run it with piboxd running to complete those unit test runs.
I can then package piboxlib for rpi4's archive and rebuild the rootfs and staging tree. Then I can start to update the apps to use the updated piboxMsg() function.

Next problem: picam worked after fixing a few bugs in libpibox but it didn't switch to the correct VT on exit. I have a bug report (RM #751) for adding a function to libpibox for fixing this.
After finding the right vtsrc I was able to verify that the old picam is working. I believe the new picam will also work but need to retest it. I just set vtsrc in the config file to correct vt where X is running.
