- 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.

Also expands pathname arguments as strings in a lot more system call
trace messages and fixed the poll wrapper to not be x86 specific.

clever idea. There's no reason to assume the assembler is in
.text-mode when it encounters them, and as gcc 2.96 rudely
demonstrates, sometimes it isn't. So put .text in front of all of
them.

source it turns out that there are five different versions of mmap for
the three platforms we currently support:
- On x86-linux there is mmap (aka old_mmap) which takes the
arguments in a memory block and the offset in bytes; and
mmap2 (aka sys_mmap2) which takes the arguments in the normal
way and the offset in pages.
- On ppc32-linux there is mmap (aka sys_mmap) which takes the
arguments in the normal way and the offset in bytes; and
mmap2 (aka sys_mmap2) which takes the arguments in the normal
way and the offset in pages.
- On amd64-linux everything is simple and there is just the one
call, mmap (aka sys_mmap) which takes the arguments in the normal
way and the offset in bytes.
To reconcile all this I have created a generic handler and then
written five platform specific wrappers which normalise all the
arguments and then call the generic handler.
I have also modified the address space manager to use mmap2 rather
than mmap on x86 and ppc32 so that large offsets can be correctly
handled.
There is still an issue of OffT truncating offsets as we go through
the address space manager that will need to be addressed.

and so is not part of a module cycle. This requires a moderately
grotty hack of passing a continuation-function pointer in a global
variable.

changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.
