reason:
1 On different architectures, we can utilize more optimized strategies
to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

All modern desgin support stack pointer and it's also an
important information, so let's standardize this interface.

To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG. The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
arch/mips/src: Previous commit used CP0 register definitions that were not defined in the cp0.h header file. Probably these were from the Microchip hacked up GCC toolchain but are not generally available. Fix: Add definitions to NuttX cp0.h header file.
mm/iob: Eliminate some warnings about testing the value of an undefined pre-processor variable.
