PIC32MZ: Add beginnings of CPU initialization logic.  Still some bad logic for setting up peripheral clocking

fs/aio: Corrrect some backward tests in aio_read() and aio_write(): Socket descriptors have higher numbers than file descriptors.  In aio_contain(),  Copy u.ptr (void *) when initializing aioc and not the case specific u.aioc_filep.  From Michal Ulianko.

CAN driver:  Another Ooops... Cannot save the updated driver open count if the we fail to initialize the CAN driver, causing the open to fail

CAN driver: Oop. unlink method does not exist if there operaions on the pseudo filesystem are disabled

boards.

this line "dev->cd_ocount = tmp;" needs to be moved a few lines down otherwise the open count will only be incremented from 0 to 1. This causes problems when trying to open the can bus from two different tasks.

SourceForge Patch #46 from Anonymous

PIC32MZ: Make sure that the microMIPS ISA is selected on all common MIPS32 assembly files when the PIC21MZ is selected

MIPS:  Add some build support for the M14K and also for the PIC32MZ Starter Kit.  Still a long way to go

Add basic board support for the PIC32MZ (can't build yet of course because there is not yet any PIC32MZ support)

Add path for Pinguino tools.  Need to be careful because bin directory has an incompatible make.exe in it
