7bdbf7377f Factor out differences between VG_(system) and PRE(execve). Required moving 
mash_colon_env() from vg_syscalls.c to vg_mylibc.c.  Saved 20 lines of code.

75a8dd5ba2 Removed cruft from vg_scheduler.c: 
� things not used any more, eg. global variables
 - removed some things from vg_include.h, making them local -- functions,
   variables and macros
 - other minor clean-ups

9a31e70a79 Cleaned up vg_include.h: 
- removed various things that are no longer used
- made (module-)local some things that were global
- improved the formatting in places

Removed about 160 lines of code, and non-trivially reduced the number
of global entities.

1eb570df2c Restructured the as_*() functions so they are simpler and there is no implicit 
global state -- the state is threaded explicitly through via function arguments
and return values.  ume.c now has no global variables, which is nice.

Also removed a redundant as_pad() call in stage2's main() which meant
layout_client_space() could be merged with layout_remaining_space().

Also removed a couple of no-longer-used variables and #defines.

f10c38f7e5 Modify the ipc system call so that only those calls which may block 
are treated as blocking.

This fixes bug #86000 because shmat is no longer treated as blocking
and it is therefore no longer possible for two threads to try and use
the same address for the shared memory segment.

b5f08d077f Add support for allowing the POST function for a system call to be called 
even when the system call fails, and allow the PRE function to modify the
system call flags.

Also fix nanosleep so that it only marks the returned time as defined
if the system call exited with EINTR due to be interrupted.

5cb175294a Fix the skiplist brokenness Nick found: 
- use a simple memset to initialize the next pointer vector
 - fix some previously unexercised code as a result of the above
Still haven't verified we're actually getting skipping, but it doesn't
crash with a make regtest.

dbc191490a Er, actually make this test meaningful. It now aborts correctly if you try to 
launch stage2 directly, rather than giving an obscure error about the tool
later on.

e1cc11b7c6 Move the decoding of SFENCE out of the SSE only part of disInstr as it 
exists on Athlon's that have MMXEXT support and those don't have SSE state
so won't decode it where it was.

ff1439fd06 Fix extremely obscure bug in xadd picked up by QEMU's test suite. The 
(almost useless) instruction "xadd %reg,%reg" gave the wrong answer
due to a subtlety of the order in which the destination registers are
PUTted to.

d6c41529d5 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.

Hopefully fixes #84978 (unconfirmed)
