rMPP support

[xugro]

tried to make rm2fb work for the pro (started with the initial poc as it seemed simpler)
https://github.com/xugro/rmpp-framebuffer (will fork this repo, this was just for testing/finding the function addresses)

Can someone share the result of dump_qtClass on rm2 so I can compare it with my result and see what's missing?

I found the address of getInstance (i think) and something to update the screen but it just clears everything and I couldn't get the painter working.

TODO:

• make a better todo list
• find how the update command and fb work
• shim the create/wait/shutdown functions to launch xochitl as normal with the server working

opened this issue thanks to Eeems' comment
here is the output of dump_qtClass for the pro:

Qt depends on a UTF-8 locale, but has failed to switch to one.

I want to just compile the normal rm2fb app with the two addresses I found but would that cause a soft brick? As long as I can still kill it with ssh, it shouldn't be a problem.
