Add a generic test for <scsi/sg.h> availability to fix build with
Bionic libc that does not provide <scsi/sg.h>.
* configure.ac (AC_CHECK_HEADERS): Add scsi/sg.h.
* ioctl.c (ioctl_decode): Do not call scsi_ioctl if !HAVE_SCSI_SG_H.
* scsi.c: Do not compile scsi ioctl decoding if !HAVE_SCSI_SG_H.

Been playing with UBI of late and it'd help if I could see what it was
doing. Not entirely sure about the decoding of UBI_IOCVOLUP -- it takes
a pointer to a 64bit value, not a strict.
* util.c (MAX, MIN): Move to ...
* defs.h (MAX, MIN): ... here.
(CLAMP): Define.
(ubi_ioctl): New prototype.
* ioctl.c (ioctl_decode): Call ubi_ioctl when code is 'o' or 'O'.
* mtd.c: Include ubi user API header.
(ubi_volume_types): New enum decode.
(ubi_volume_props): Likewise.
(ubi_ioctl): Define.
* linux/ubi-user.h: Import from linux 3.8.
This is a preparatory mass replace patch with no code changes.
The future change will need to typedef sysent to sysent0,
which results in compile failures when "struct sysent" string
gets mangled into "struct sysent0".

Needed to debug some losetup failures, and it's easier when you can see
what the kernel is getting vs what you think you're sending, so add some
decoders for those ioctls.
* loop.c: New file.
* Makefile.am (strace_SOURCES): Add loop.c.
* defs.h (loop_ioctl): New prototype.
(string_quote): Likewise.
* ioctl.c (ioctl_decode): Call loop_ioctl when code is 'L'.
* util.c (string_quote): Remove static keyword.

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.

Thank you Dmitry for spotting it.
* ioctl.c (compare): Partially revert last change - the new
comparison logic was buggy.

The files not mentioned in changelog below had only
copyright notices fixes and indentation fixes.

non-Linux architectures.
* Makefile.am: Remove if LINUX/endif pairs.
* defs.h: Remove stream_ioctl() declaration.

Trivial shuffling of data tables puts them all in one file,
allowing gcc to see their sizes and eliminate variables
which store these sizes.
Surprisingly, in C mode gcc does not optimize out static const int
variables. Help it by using enums instead.
* defs.h: Stop exporting ioctlent{0,1,2}, nioctlents{0,1,2},
signalent{0,1,2}, nsignals{0,1,2}.
* ioctl.c: Remove definitions of ioctlent{,0,1,2} and nioctlents{,0,1,2}.
* signal.c: Remove definitions of signalent{,0,1,2} and nsignals{,0,1,2}.
* syscall.c: Move above definitions to this file. Make them static const
or enums if suitable.
* block.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* defs.h [LINUX] (block_ioctl): New function.
* ioctl.c (ioctl_decode) [LINUX]: Use it to decode HDIO_* and BLK*
ioctls.
