df13f9efcc Further un-break signal handling following the merge. It's really 
scandalous how difficult it is to figure out what code messes with
what global state, and generally how stuff is supposed to work.

56bce432c3 Get rid of the VALGRIND_INTERNAL_PRINTF_BACKTRACE request -- it's no longer 
used.

And move VALGRIND_INTERNAL_PRINTF() out of core.h into vg_replace_malloc.c,
which is the only place it's used now.  Also made it print it's message with
Vg_DebugMsg rather than Vg_UserMsg, which makes more sense, since it's used
for --trace-malloc which is debugging-style info.

Improved some comments about this stuff too.

6ddcb7dc7d Detect and reject misaligned args for mmap. This makes 
none/tests/map_unaligned work.  The PRE handlers for sys_mmap and
sys_old_mmap are more convoluted than I would like, and might benefit
from a rewrite.

0356d27ca6 Merge in changes from the 2.4.0 line. This basically brings in the 
overhaul of the thread support.  Many things are now probably broken,
but at least with --tool=none, simple and not-so-simple threaded and
non-thread programs work.

achieves.

006c9e84c3 When handling syscalls, don't try to figure out if the pre-handler set 
the syscall result by inspecting RES after the pre-handler has run.
Instead, give each thread a syscall_result_set Bool, and make
SET_RESULT set it.  Inspect that Bool.

2cfb6bc855 On AMD64 it's valid to access up to 128 bytes below %rsp. Or to be 
more accurate, on the amd64-linux ABI that is allowable.  Anyway,
parameterise the signal handler so it isn't confused by such accesses.

245173117c Major rewrite of the machinery which keeps track of segments: 
* remove initialisation-time circularities by not using the
  skiplist mechanism and therefore not using any dynamically
  allocated memory in support of this mechanism

* Add comments about how it works (it is pretty opaque) so as
  to help future maintainers/bug-fixers

It only just works and many things are still broken.  That should
improve rapidly however.
