Kernel+LibC+crash: Add mprotect() syscall
This patch adds the mprotect() syscall to allow changing the protection flags for memory regions. We don't do any region splitting/merging yet, so this only works on whole mmap() regions. Added a "crash -r" flag to verify that we crash when you attempt to write to read-only memory. :^)
