Revert r51108. ProbeForRead doesn't check if memory is readable.
Improve comments and replace trick raising exception with call to ExRaiseAccessViolation.
[WIN32K]
Remove ASSERTs in IntSetSysColors: this function is only called in NtUserSetSysColors in SEH block. It shouldn't crash for NULL pointers.

- Reformat and cleanup the entire file, deprecate NtVirtualLock/Unlock which didn't really work (and aren't really required for any apps for now)
- Major perf optimizations to NtRead/VirtualMemory: Use pool memory transfer when more efficient than MDL, and use local stack buffer when size permits.
- This patch provides up to 109% improvement (more than twice as fast) in certain virtual memory operations.
- Thanks to Alex for researching this issue, and providing the internal information on the various optimizations and behaviors the NT implementation uses.

- Removed a bunch more i386-only exports from the ARM kernel.
- Implemented all the READ/WRITE_REGISTER* routines for ARM/PPC.
- Implement half of KiSoftwareInterruptException, which calls KiSoftwareInterruptHandler, which calls KiSystemService. We now reach the first kernel-mode system call! (ZwClose from PspInitPhase0).
- Reformat fastinterlck.c and change the way it's included per-architecture.

- There is no reason to implement the Interlocked* APIs in assembly in the kernel -- just have them call the intrinsics.
- Also fix the way we were overloading the exported APIs, we now use the intrinsics all the time.
- Convert loader block address to virtual, and parse the addresses inside it and convert them to virtual too, after we don't use them in FreeLDR anymore -- the kernel will delete the p->v identity mapping, and eventually still need to touch the loader block.
- Implement MmGetPhysicalAddress and MiGetUserPageDirectoryCount for ARM.
- We now reach the point where we start initializing the boot drivers' memory information.
