Take #2 on mainlining strace support for ARC (last one was 4.6 based back
in March 2011), see
http://sourceforge.net/p/strace/mailman/message/27210168/
The syscall ABI is asm-generic/unistd.h based (so no legacy syscalls),
hence very similar to metag port.

Add support for Imagination Technologies Meta architecture (the
architecture/ABI is usually referred to as metag in code). The Meta
Linux kernel port is in the process of being upstreamed for v3.9 so it
uses generic system call numbers.
sys_lookup_dcookie writes a filename to buffer argument, so I've set
TF flag.
nfsservctl appears to be set to sys_ni_syscall in asm-generic/unistd.h
so I've left it blank.
truncate64/ftruncate64/pread64/pwrite64/readahead have unaligned 64bit
args which are packed tightly on metag, so less arguments on metag.
fchdir/llseek takes a file descriptor so s/TF/TD/
sync_file_range has 2 64bit args so uses 6 args, so s/4/6/
timerfd_create/msgget/msgctl/msgrcv/semget/segtimedop/semop/shmget/
shmctl/shmat/shmdt/recvmsg/migrate_pages have different number of args.
oldgetrlimit is just getrlimit for metag.
add TM flag to various memory syscalls.
metag doesn't directly use sys_mmap_pgoff for mmap2.
prlimit64/process_vm_readv/process_vm_writev take a pid so add TP flag.
fanotify_init doesn't appear to take a file descriptor so remove TD.

ARM in fact _is_ one personality.
We had two personalities for it because it has a handful of
syscalls with huge scnos (0x000f00xx).
Extending syscall table to have [0x000f0005] index is of course
not a good idea.
Someone decided to handle that by having a separate personality
just for these syscalls.
But multi-personality arch does a bit more work in other parts.
This patch is another alternative: "move" 0x000f00nn syscalls
down to the entries just above last ordinary syscall,
by manipulating scno if it falls into the 0x000f00xx range.
In order to not worsen genuine undefined scnos' printing,
the code remaps scno back to actual value before printing
"syscall_NNN" string.

Previous code merges too many similar, but different ways
of decoding mmap. For example, sys_old_mmap is "params in memory"
API... except SH[64], where it is "params in regs",
i.e. what sys_mmap ("new mmap") function does on other arches!
It's much simpler when every mmap handler has same API regardless
of arch. Where API means whether params are in regs or in memory,
and whether offset is in bytes, pages, or 4k blocks.
Then we just insert correct function pointers into
arch syscall tables.
It turns out there are four common mmap APIs over
all architectures which exist in Linux kernel,
and one outlier for S390.
A number of mmap decoders were plain wrong in arch tables.
For example, BFIN has no old_mmap. It returns ENOSYS.
I checked kernel sources for all arches nad fixed the tables.
There was dead code for x86_64 for old_mmap:
