add ioperm/iopl syscalls
based on patches by orc and Isaac Dunham, with some fixes. sys/io.h exists and contains prototypes for these functions regardless of whether the target arch has them; this is a bit unorthodox but I don't think it will break anything. the function definitions do not exist unless the appropriate SYS_* syscall number macro is defined, which should make sure configure scripts looking for these functions don't find them on other systems. presently, sys/io.h does not have the inb/outb/etc. port io macros/functions. I'd be surprised if ioperm/iopl are useful without them, so they probably need to be added at some point in appropriate bits/io.h files...
