- Introduced VG_SYSNUM_STRING and VG_SYSNUM_STRING_EXTRA which factor out
differences in the way syscall numbers are printed on different platforms.
This gets rid of seven "DDD" fixme-style comments.
- This also meant that Darwin syscall numbers are now printed in a
non-ambiguous way -- previously Unix, machine-dependent and diagnostic
syscalls were all printed the same way, even though their numbers overlap.
Now each number is prefixed with "unix", "mdep", etc. And Mach trap
numbers aren't printed as negative numbers now that they have a "mach"
prefix.
- Split each of pub_core_vkiscnums.h and pub_tool_vkiscnums.h into two
parts, one suitable for inclusion in asm files, one suitable for inclusion
in C files; in both cases the latter includes the former. This makes
this module more like other modules that have asm-only components (eg.
m_transtab); it also allows the hacky VG_IN_ASSEMBLY_SOURCE macros and
tests to be removed.
- Removed some of the VG_DARWIN_SYSNO_* macros that were no longer needed,
and renamed some of the existing ones to make their meanings clearer.
- Added comments on the encoding of Darwin syscall numbers so it's
possible for mortals to understand without reading the kernel code..

DARWIN branch. A big ugly DARWIN/trunk sync commit, mostly to do with
changing the representation of SysRes and vki_sigset_t. Functionality of
the trunk shouldn't be changed by it.

- track SysRes changes
- track VG_(am_find_nsegment) const-ness change
- increase number of client syscall args supported from 6 to 8
- simplify type SyscallStatus. Simply hold a copy of the SysRes
for the syscall rather than have this be a data structure
incorporating something very similar to the fields of a SysRes,
and more besides. Change various macros in priv_types_n_macros.h
to match.
- syswrap-main.c: instantiate the various impedance-matching
functions for AIX.

instead of sigprocmask.
In the process, discover that error handling for
ML_(do_syscall_for_client_WRK) on all platforms has always been
broken, in the sense that the sigprocmasks (which are important) could
silently fail. This commit fixes that up too (only on ppc64-linux at
the moment, so all other platforms are probably broken now).

do_syscall_for_client_WRK() needed a bigger stack to avoid the linkage area.
always use dot_prefix for label calls
not wrapping assembly with
.section ".text"
...
.previous
- ppc64 doesn't like it... seems we can't 'stack' more than one section to pop off with .previous ?
