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.

Change VG_(allocEltDedupPA) to return a pointer to const. The reason is
that once an element has been allocated and added to the pool it must
not be modified afterwards. See the documentation in pub_tool_deduppoolalloc.h
The rest of the patch is ripple.

Extend the behavioural-equivalence-class mechanism for redirection
functions to include the ability to give a priority to each function,
as well as a tag indicating its behavioural class. Add logic in
m_redir.c to resolve conflicting redirections with the same eclass but
different priorities by preferring the redirection with the higher
priority. Use all of the above in mc_replace_strmem.c, to cause a
conflict between redirections for "memcpy" and "memcpy@GLIBC_2.2.5" to
be resolved in favour of the latter (the non-overlap-checking
version).
This is all related to the massive swamp that is #275284.

Add more infrastructure to be used for fixing #275284 (Valgrind
memcpy/memmove redirection stopped working in glibc 2.14/x86_64), but
don't fix the problem yet. Should be no end-user visible change.
* in m_redir.c, when processing redirection specifications, consider
all the names associated with an address, not just the primary name.
* add plumbing to support the notion of "behavioural equivalence class
tags" of redirect/wrap functions. These can be used by m_redir to
resolve some situations in which the available set of redirect
specifications causes some address to get redirected to two
different functions. (Framework is in place, but such resolution is
not implemented yet.)

Cleaned up the demangling mess:
- Now more clearly distinguishing between C++-demangling, Z-demangling, and
below-main renaming, particularly in 'get_sym_name'.
- --demangle=no no longer prevents Z-demangling, which makes more sense,
although it's unlikely to affect anyone.
- Broke the circular dependency between m_demangle and m_debuginfo by moving
below-main renaming into m_debuginfo.
- Renamed some get_fnname_* functions to make their effect clearer, and
improved their comments.

Cleaned up the mess that was the treatment of "below main" functions such as
'__libc_start_main', in Massif, m_debuginfo and m_stacktrace. As part of
this, --show-below-main is now visible to tools, and Massif pays attention
to it.
Improved the description of --show-below-main=yes in the manual.
Replaced some instances of "__libc_start_main" in the test *.exp files with
"(below main)", which is what will actually be seen. Also updated
scalar.stderr.exp*, which should make it get closer to actually passing.
