bit-rotted badly and was clogging up the code.
I put the useful remnants in docs/porting-to-ARM in case anyone ever
wants to try porting to ARM again.

m_stacks, because it's a nicely distinct and stand-alone piece of
functionality. This happily removes m_aspacemgr's dependence on
m_mallocfree (there was an apparent dependence due to the #include, even if
it didn't manifest itself in practice -- very important!) and m_options (not
so important).

things. These made sense when the arch/OS/platform-specific code was in
one module, but as that code got mixed in with generic code the boundary
between generic and non-generic blurred, and the distinction made less
sense. So let's get rid of them.

module-local, use the new ML_ prefix instead of VG_. This makes it
trivial to see which names are those exported from public module
interfaces: precisely those using VG_.
/* VG_ is for symbols exported from modules. ML_ (module-local) is
for symbols which are not intended to be visible outside modules,
but which cannot be declared as C 'static's since they need to be
visible across C files within a given module. It is a mistake for
a ML_ name to appear in a pub_core_*.h or pub_tool_*.h file.
Likewise it is a mistake for a VG_ name to appear in a priv_*.h
file.

not really from the kernel and they're defined in terms of VG_(max_signal),
which is in m_signals. Renamed them with the VG_ prefix too, since they're
now not part of the kernel interface.

I've changed it so it now is, which makes it consistent with the
other 'needs'. Because of this, I was also able to invert the dependence
between m_mallocfree and m_tooliface, which is related to setting
the redzone size for client heap blocks. As a result, m_tooliface
now doesn't depend on anything except pub_core_basics.h, hooray!

Thanks, Paul, for having your ppc port of valgrind 2.4 to work from!

Removes the dependence of m_scheduler/ on m_main.c; reduces the
dependence of m_signals.c on m_main.c.

- Broke part of m_scheduler off into a new module m_threadstate. It
contains ThreadState, VG_(threads)[] and some basic operations on the
thread table. All simple stuff, the complex stuff stays in m_scheduler.
This avoids lots of circular dependencies between m_scheduler and other
modules.
- Managed to finally remove core.h and tool.h, double hurrah!
- Introduced pub_tool_basics.h and pub_core_basics.h, one of which is
include by every single C file.
- Lots of little cleanups and changes related to the above.
- I even did a small amount of documentation updating.

does and better distinguishes it from m_syscall. Did everything for this
except renaming the m_syscalls/ directory -- I'll do that shortly, I don't
think Subversion can handle renaming a directory and files within that
directory at the same time.

m_syscall.c. Plus some associated cleanups.
Moved VG_(sigreturn) into m_signals.c and made it local.

needs to #include pub_core_mallocfree.h. As a result, we need
to #include it explicitly everywhere else.

the m_syscalls module. Fundamentally the aim of the overhaul is to
clean up the logic and abstractions surrounding syscalls in order that
we can cleanly support ppc32 and other new targets. Aims in detail:
* To further decouple the syscall PRE/POST wrappers from specifics of
how those values are stored on a given platform. The wrappers look
the same as they did before, mostly (eg, references to ARGn and
RES are unchanged), but now those macros refer to values in structs
SyscallArgs and SyscallStatus (see priv_types_n_macros.h).
* Complete overhaul of the driver logic for syscalls. The resulting
logic is algorithmically identical to what we had before, but is
more documented, and deals with moving arg/result data between
platform specific representations and the canonical forms in
structs SyscallArgs and SyscallStatus.
* Also as a result of this change, remove problems in the old logic
due to assignments of RES in PRE wrappers trashing the ARGs whilst
we still need to see them.
* Lots of other cleanups and documentation. There is extensive
commentary in syscalls-main.c.
The driver logic has been placed in its own file, syscalls-main.c.
New/deleted files in m_syscalls:
* syscalls.c is divided up into syscalls-main.c, containing driver
logic, and syscalls-generic.c, containing generic Unix wrappers.
* priv_syscalls.h is chopped up into priv_types_n_macros.h
and priv_syscalls-{generic,main}.h.
------------
All the above changes are in m_syscalls. However there is one
system-wide change as a result of all this.
The x86-linux assumption that syscall return values in the range -4095
.. -1 are errors and all others are values, has been done away with
everywhere. Instead there is a new basic type SysRes which holds a
system call result in a platform-neutral way.
Everywhere that previously an Int would have held a system call
result, there is now a SysRes in its place.
------------
Almost everything works on SuSE 9.1 (LinuxThreads) again. NPTL will
still be majorly broken; I will commit fixes shortly. AMD64 is also
totalled. I will get to that too.

As part of this, killed the VG_STRINGIFY macro, which was used to expand
out names like "VG_(foo)" and "vgPlain_foo" in assertion failure
messages. This is good since we actually want the "VG_(foo)" form used
in these messages.

relying on any other modules -- in m_libcbase.
Also converted the 'size' parameters to functions like VG_(memcpy) and
VG_(strncpy) from Int to SizeT, as they should be.
Also removed VG_(atoll16) and VG_(toupper), which weren't being used.
Also made VG_(atoll36) less flexible -- it now only does base-36 numbers
instead of any base in the range 2..36, since base-36 is the only one we
need. As part of that, I fixed a horrible bug in it which caused it to
return incorrect answers for any number containing the digits 'A'..'I'!
(Eg. for "A; it would return 17 instead of 10!)
Had to disable the assertions in VG_(string_match), since this module can't
see vg_assert, which wasn't ideal but also isn't a disaster.

sensible now -- no vg_dummy_profile.c, no silly #including of
vg_profile.c from tools.
Unfortunately, it still doesn't work, due to bad interactions
with signal handling that I don't understand.
