Merge r14202 from the BUF_REMOVAL branch to trunk.
This patch changes the interface and behaviour of VG_(demangle) and
VG_(maybe_Z_demangle). Instead of copying the demangled name into a
fixed sized buffer that is passed in from the caller (HChar *buf, Int n_buf),
the demangling functions will now return a pointer to the full-length
demangled name (HChar **result). It is the caller's responsiblilty to
make a copy if needed.
This change in function parameters ripples upward
- first: to get_sym_name
- then to the convenience wrappers
- VG_(get_fnname)
- VG_(get_fnname_w_offset)
- VG_(get_fnname_if_entry)
- VG_(get_fnname_raw)
- VG_(get_fnname_no_cxx_demangle)
- VG_(get_datasym_and_offset)
The changes in foComplete then forces the arguments of
- VG_(get_objname) to be changed as well
There are some issues regarding the ownership and persistence of
character strings to consider.
In general, the returned character string is owned by "somebody else"
which means the caller must not free it. Also, the caller must not
modify the returned string as it possibly points to read only memory.
Additionally, the returned string is not necessarily persistent. Here are
the scenarios:
- the returned string is a demangled function name in which case the
memory holding the string will be freed when the demangler is called again.
- the returned string hangs off of a DebugInfo structure in which case
it will be freed when the DebugInfo is discarded
- the returned string hangs off of a segment in the address space manager
in which case it may be overwritten when the segment is merged with
another segment
So the rule of thunb here is: if in doubt strdup the string.

Give function copy_input_until_stop the noinline atribute.
At least one of the compilers for s390x nightly builds was inlining it.
Update exp files accoordingly. This should fix any residual back-trace
noise for this testcase.

Merge some minor regtest updates from the DARWIN branch:
- avoid using <malloc.h> where it's not necessary, because on DARWIN it's
called <malloc/malloc.h>
- filter the output of brk2 more, which allows the .stderr.exp2 file to be
removed.

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.
