Eliminate many SCNO_IS_VALID checks
By adding tcp->s_ent pointer tot syscall table entry,
we can replace sysent[tcp->scno] references by tcp->s_ent.
More importantly, we may ensure that tcp->s_ent is always valid,
regardless of tcp->scno value. This allows us to drop
SCNO_IS_VALID(tcp->scno) checks before we access syscall
table entry.
We can optimize (qual_flags[tcp->scno] & QUAL_foo) checks
with a similar technique.

Clean up mmap decoding
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:
x86_64 has no old_mmap.
* mem.c: Refactor mmap functions so that we have five mmap syscall
handlers, each with the fixed API (not varying by arch).
* pathtrace.c (pathtrace_match): Adjust sys_func == mmap_func checks.
* linux/syscall.h: Declare new mmap syscall handler functions.
* linux/arm/syscallent.h: mmap2 is sys_mmap_pgoff.
* linux/avr32/syscallent.h: mmap is sys_mmap_pgoff.
* linux/bfin/syscallent.h: old_mmap is ENOSYS, mmap2 is sys_mmap_pgoff.
* linux/hppa/syscallent.h: mmap2 is sys_mmap_4koff.
* linux/i386/syscallent.h: mmap2 is sys_mmap_pgoff.
* linux/ia64/syscallent.h: mmap2 is sys_mmap_pgoff.
* linux/m68k/syscallent.h: mmap2 is sys_mmap_pgoff.
* linux/microblaze/syscallent.h: old_mmap is sys_mmap, mmap2 is sys_mmap_pgoff.
* linux/mips/syscallent.h: mmap is sys_mmap_4kgoff.
* linux/or1k/syscallent.h: mmap2 is sys_mmap_pgoff.
* linux/powerpc/syscallent.h: mmap2 is sys_mmap_4kgoff.
* linux/s390/syscallent.h: mmap2 is sys_old_mmap_pgoff.

Add x32 support to strace
X32 support is added to Linux kernel 3.4. In a nutshell, x32 is x86-64 with
32bit pointers. At system call level, x32 is also identical to x86-64,
as shown by many changes like "defined(X86_64) || defined(X32)". The

Roll back "die on malloc failure" behaviour a bit
After recent change, select(2^31-1, NULL, NULL, NULL)
would make strace exit. This change caps fdsize so that
it is always in [0, 1025*1024], IOW: we will try to allocate at most
1 megabyte, which in practice will almost always work,
unlike malloc(2Gig).
* desc.c (decode_select): Cap fdsize to 1024*1024.
* pathtrace.c (pathtrace_match): Cap fdsize to 1024*1024.
* file.c (sys_getdents): Cap len to 1024*1024.
(sys_getdents64): Cap len to 1024*1024.
* util.c (dumpiov): Refuse to process iov with more than 1024*1024
elements. Don't die on malloc failure.
(dumpstr): Don't die on malloc failure.

Whitespace cleanups. no code changes.
* bjm.c: Fix tabulation (such as extra spaces before tabs),
convert punctuation where it deviates from prevalent form
elsewhere in strace code, convert sizeof and offsetof where
it deviates from from prevalent form, remove space between
function/macro/array names and (parameters) or [index],
add space between "if" and (condition), correct non-standard
or wrong indentaion.
