Add an extra flags argument to uvm_io(), to specify whether we want to fix
the protection of the memory mapping we're doing I/O on, or if we want to
leave them as they are. This should only be necessary for breakpoint
insertion in code, so we'll only use it for ptrace requests.
Initially from art@ after discussion with kettenis@ millert@ and I,
tested by many.
