4f750b9ad1 Add decoding for evdev ioctls
This patch introduces decoding for evdev ioctls.  For EVIOCSFF the five

tested on x86_64 with Linux 3.13.

df7aa2b19e ioctl: take all 32 bits of ioctl commands into account
Historically, only 16 bits (8-bit number and 8-bit type) of 32-bit ioctl
commands were used for decoding, which was the source for numerous
annoying collisions like this:

	ioctl(0, SNDCTL_TMR_TIMEBASE or SNDRV_TIMER_IOCTL_NEXT_DEVICE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
	ioctl(0, MGSL_IOCGPARAMS or MMTIMER_GETRES or MTIOCTOP or SNDCTL_MIDI_MPUMODE, 0x7fffd47f7338) = -1 ENOTTY (Inappropriate ioctl for device)

The solution is to use all 32 bits for decoding, not just "number" and
"type", but also "size" and "direction".

As some architectures override defaults that come from asm-generic/ and
provide alternative definitions for some ioctl commands, we support
per-architecture ioctl definitions and merge them with common
definitions at build time.  During the merge, we used to keep both
generic and architecture-specific definitions, now architecture-specific
definitions have precedence over generic ones -- ioctlsort omits
definitions from asm-generic/ for those ioctl names that have different
definitions in asm/.

Additional bits of "direction" are architecture specific -- the number
of bits and their values differ between architectures.  To reduce
architecture differences in the source code, we keep "direction" in
symbolic form and compile it in ioctlsort.

Additional bits of "size" are also architecture specific -- not only the
number of bits differ between architectures, but sizes of many types
depend on sizeof(long).  To reduce architecture differences in the
source code, we keep 32-bit and 64-bit versions of common ioctl
definitions, and use the appropriate version for each architecture and
personality.

To implement this, the tools for generating ioctl definitions from
kernel headers have been rewritten, and the source format of ioctl
definitions has been extended.   The final ioctlent*.h files that are
included by syscall.c are now generated from source ioctls_inc*.h and
ioctls_arch*.h files at build time with ioctlsort.

c7afb4881f ioctl: assume that all ioctl commands have unsigned int type
In linux, ioctl command number has a 32-bit unsigned integer type:
	fs/ioctl.c:SYSCALL_DEFINE3(ioctl, unsigned int, fd, unsigned int, cmd, unsigned long, arg)

why should strace care?
Let's follow the kernel and treat it as unsigned int.

39fca62801 Small optimization in signal and ioctl tables
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.
