PruManager RProc+UIO implementation

DhruvaG2000 commented 3 years ago

The code has been tested on the BELA image so far using the sample_streamer example.

I am able to get audio output fine.
So far I have ported all the prussdrv functions mentioned here on forum into PruManager.
If this PR receives your approval(ie. if the code looks okay to you) then I can move on to work on debugging Rproc using newer TI 4.19 kernels, as UIO is possibly not properly working even on the BBB v4.19. I planned to do this in a step by step approach first where I first start by replacing only the start stop using rproc and let uio handle the rest. However in the light of the fact that UIO drivers aren't working properly, I will need to completely adapt to RProc + Mmap approach in one go (which can take upto a week or two)

I'd prefer const std::string&

Well but the prussdrv function accepts a char* as argument so to avoid str.c_str(); I used this. But if you prefer that, then I will use string.

rproc + uio stuff refactored and (until 551dd96d5a0dabe229923c3923122e3c3cb4e73c) merged into multi-codec
