libpthread implementation: USERREQ__READ_MILLISECOND_TIMER, USERREQ__MALLOC,
USERREQ__FREE.
As a consequence, all the PTHREQ macros (eg. VGA_PTHREQ_RET,
SET_PTHREQ_RETVAL) could be removed. And VG_(tl_malloc_called_by_scheduler)
has been renamed VG_(tl_malloc_called_deliberately) to reflect how its role
has changed.

amd64 version is broken again. Writing code with undocumented
assumptions should be a firable offense. At the very least.

in registers. Replace it (for amd64) with something more disciplined:
call_on_new_stack_0_0 and call_on_new_stack_0_1.

more accurate, on the amd64-linux ABI that is allowable. Anyway,
parameterise the signal handler so it isn't confused by such accesses.

string in valgrind.pc.in, so that they describe Valgrind as a "dynamic
binary instrumentation framework", and don't mention platforms at all.
I had to tweak the regtest filters a bit for this.

through once, failing to find the translation, and falling back to the
scheduler.
Did a couple of minor associated cleanups too.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3171
- Fix bogus assertion in vg_transtab.c
- Do null implementation of --pointercheck
We now reach the dispatch loop!
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3166
- implemented VG_(clone)()
- implemented PLATFORM_DO_MMAP()
- implemented VG_(init_thread1state)() [will need to be updated as the
Vex AMD64 guest state is updated]
- implemented OYNK, because it's useful
Also a couple of general cleaning up things.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3165
- implemented VG_(do_syscall)()
- fixed a problem in ume.c with mapping when loading, which was causing
stage2's memory to be trashed
- fixed stage2.lds substitution so stage2 goes in the right address

It compiles, but aborts immediately if you try to run it.
I didn't include ldt.c; I'm not sure how the LDT is used on AMD64. It can be
added later if necessary.
While doing this, did some 64-bit cleanness fixes:
- Added necessary intermediate casts to ULong to avoid warnings when converting
ThreadId to void* and vice versa, in vg_scheduler.c.
- Fixed VALGRIND_NON_SIMD_CALL[0123] to use 'long' as the return type.
- Fixed VALGRIND_PRINTF{,BACKTRACE} to use unsigned longs instead of unsigned
ints, as needed.
- Converted some offsets in vg_symtab2.h from "Int" to "OffT".
- Made strlen, strncat, etc, use SizeT instead of 'unsigned int' for the length
parameter.
- Couple of other minor things.
I had to insert some "#ifdef __amd64__" and "#ifndef __amd64__" guards in
places. In particular, in vg_mylibc.c, some of our syscall wrappers aren't
appropriate for AMD64 because the syscall numbering is a bit different in
places. This difference will have to be abstracted out somehow.
Also rewrote the sys_fcntl and sys_fcntl64 wrappers, as required for AMD64.
Also moved the ipc wrapper into x86, since it's not applicable for
AMD64. However, it is applicable (I think) for ARM, so it would be nice
to work out a way to share syscall wrappers between some, but not all,
archs. Hmm. Also now using the real IPC constants rather than magic
numbers in the wrapper.
Other non-AMD64-related fixes:
- ARM: fixed syscall table by accounting for the fact that syscall
numbers don't start at 0, but rather at 0x900000.
- Converted a few places to use ThreadId instead of 'int' or 'Int' for
thread IDs.
- Added both AMD64 and ARM (which I'd forgotten) entries to valgrind.spec.in.
- Tweaked comments in various places.
