The calls homebrew starts the ME with (1.50's NIDs, and 3.71's for the
ME's reset and bus clock) set or clear a bit of the reset or bus clock
register the way the firmware's driver does, returning whether it was
set. Only those NIDs, so a later firmware's lowio.prx keeps its own
exports under --vsh.
Kernel modules copy their ME code to the boot page with SysclibForKernel's
memcpy, which now goes through MMIO for hardware addresses like the
replaced memcpy already did (MMIO::Copy, shared).
pspsdk's mebasic, MElib's test, PSP Bunny, snes9xTYL and ProTrekkr's test
now start their ME.
