gcc sometimes generates "sbbl %reg,%reg" to convert the carry flag
into 0 or -1 in reg. This has no actual dependency on reg, but
memcheck can't see that, and so will yelp if reg contains garbage. A
simple fix is to put zero into reg before we start, zapping any
undefinedness it might otherwise contain.

Implement support for the async I/O system calls in 2.6 kernels. This
requires padding of the address space around calls to io_setup in order
to constrain the kernel's choice of address for the I/O context.

Based on patch from Scott Smith <scott-kde@gelatinous.com> with various
enhancements, this fixes bug #83060.

This commit fixes things so that the client stack can be easily placed
anywhere, even below the client executable, just by changing a single
assignment to VG_(clstk_end). I haven't actually moved the stack, though.

Merged Valgrind's heap and stack.  This has two main advantages:

1. It simplifies various things a bit.

2. Valgrind/tools will run out of memory later than currently in many
circumstances.  This is good news esp. for Calltree.

Some things were going in V's 128MB heap, and some were going in V's 128MB map
segment.  Now all these things are going into a single 256MB map segment.
stage2 has been moved down to 0xb0000000, the start of the 256MB map segment.
The .so files needed by it are placed at 0xb1000000 (that's the map_base).

This required some bootstrapping at startup for memory -- we need to allocate
memory to create the segments skip-list which lets us allocate memory...
solution was to make the first superblock allocated a special static one.
That's pretty simple and enough to get things going.

Removed vg_glibc.c which wasn't doing anything anyway.

Removed VG_(brk) and associated stuff, made all the things that were calling it
call VG_(mmap)() instead.

Removed VG_(valgrind_mmap_end) which was no longer needed.

Rejigged the startup order a bit as necessary.

Moved an important comment from ume.c to vg_main.c where it should be.
