Decode mtd ioctls
I got tired of figuring out mtd structures (which show up a lot in the embedded space), so add decoders for those ioctls. * defs.h (mtd_ioctl): New prototype. (print_loff_t): Likewise. * io.c (print_loff_t): Delete static keyword * ioctl.c (ioctl_decode): Call mtd_ioctl when code is 'M'. * Makefile.am (strace_SOURCES): Add mtd.c. (EXTRA_DIST): Add linux/mtd-abi.h. * mtd.c: New file. * linux/mtd-abi.h: New file. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
