530bed0ca8 Fix decoding of getgroups, getgroups32, setgroups, and setgroups32 syscalls
Convert parsers of these syscalls to the same scheme as were applied to
parsers of other uid/gid related syscalls.
That is, define two sets of parsers on architectures that support
(either directly or via multiarch) 16-bit and 32-bit gid getgroups
and setgroups syscalls simultaneously, and reuse essentially the same
code by parametrizing uid_t and names of parser functions.

80f7db1fed Fix decoding of 16-bit *chown and [gs]et*[gu]id syscalls
Define two sets of parsers on architectures that support (either
directly or via multiarch) 16-bit and 32-bit uid/gid syscalls

1ba85436de 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.

_exit, read, write, waitpid, execve, wait4, sysfs, readv, writev,
pread64, pwrite64, exit_group, waitid, send, recv, sendto and
