Log:
- [AUDIT] After spending some time looking at the current HAL, I believe it to be clean
and written by authors which had knowledge of system internals and have always used
clean-rooming. As well, the difference in implementation, complete and utter
incompatibility with NT as well as the presence of some Linux-based code confirms this.
- Fix function definitions of HalQueryRealTimeClock, HalGetEnvironmentVariable. They were
defined in the NDK in one way, but implemented another way, and since the HAL didn't
include its own NDK file, the compiler didn't realize this. Calls of these functions
might've experienced serious problems.
- Also fix HalHandleNmi and HalInitSystem definitions.
- Add stub code to actually setup the Clock Interrupt.
