2ebd38040f Handle sys_lookup_dcookie on amd64-linux (Andrew Haley). Also take 
the opportunity to move the handlers from syswrap-generic.c (which
they certainly aren't) to syswrap-linux.c.  Fixes #175044.

fbdd00b6e0 gcc-4.4.0 (snapshot) started complaining about buf.sem_nsems being 
uninitialised in get_sem_count().  This makes it quiet.  I am not sure
whether get_sem_count() was correct or not without it (probably was
OK).

0cf8a14c70 - Reinstate the 'atfork' from 2.4.0, which was more powerful, and expose it to 
tools.
- Factor out 'execv' from 'system' and expose it to tools.

Partly based on a patch from Robert O'Callahan.

335992d8fc Merge all remaining changes from branches/PTRCHECK. These are some 
relatively minor extensions to m_debuginfo, a major overhaul of
m_debuginfo/readdwarf3.c to get its space usage under control, and
changes throughout the system to enable heap-use profiling.

The majority of the merged changes were committed into
branches/PTRCHECK as the following revs: 8591 8595 8598 8599 8601 and
8161.

  can't be opened

  use %ld for Word arguments, and use house types

4cae5c3ed5 Merge branches/OTRACK_BY_INSTRUMENTATION into the trunk. This adds 
support to Memcheck for tracking the origin of uninitialised values,
if you use the --track-origins=yes flag.

This currently causes some Memcheck regression tests to fail, because
they now print an extra line of advisory text in their output.  This
will be fixed.

The core-tool interface is slightly changed.  The version number for
the interface needs to be incremented.

2e55cfac69 Make the clone system call wrappers call VG_(register_stack) to record 
the new thread's stack, then make the stack unwinder use that information
to make a better guess at the stack bounds.

This helps avoid crashes trying to unwind the stack under wine when
the starting point is a routine without a proper stack frame.
