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.
* linux/s390x/syscallent.h: mmap is sys_old_mmap and thus has 1 arg.
* linux/sh/syscallent.h: old_mmap2 is sys_mmap, mmap2 is sys_mmap_4koff.
* linux/sh64/syscallent.h: Likewise.
* linux/sparc/syscallent1.h: mmap is TD|TM.
* linux/tile/syscallent1.h: mmap2 is sys_mmap_4koff.

Shrink space needed by undefined syscalls in syscall tables.
Undefined syscall looked like this before this change:
{ 5, 0, printargs, "SYS_53" },
That is, "SYS_53" string had to be allocated and stored in strace binary.
Since now SCNO_IN_RANGE() macro requires sysent[scno].sys_func != NULL
for valid syscalls, we can replace printargs with NULL in such lines
and make them "invalid", thus not requiring syscall name string.
Savings on i386:
text data bss dec hex filename
237389 704 18944 257037 3ec0d strace.before
236973 704 18944 256621 3ea6d strace
Savings on mips:
336551 153692 38320 528563 810b3 strace.before
275543 153688 38320 467551 7225f strace
Tested to still decode undefined syscalls correctly (syscall no. 222 on i386).
* linux/*/syscallent.h: Replace 'printargs, "SYS_nnn"' with
'NULL, NULL'.
