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.

Some cleanup post QGetTlsAddr commit
* remove useless commented line in hgtls.vgtest
* avoid some #ifdef in arch specific code, hoping to discover more compile
time errors.

fix 338160: Implement QGetTlsAddr query so that GDB+V gdbsrv can print __thread variables.
To implement QGetTlsAddr, gdbsrv has to know how to get the glibc dtv
address and the module id from the link_map.
These 2 things are dependent on the internals of glibc.
The dependency is mostly isolated in a few lines of arch dependent
code or in an external utility that used a hack + -ldl lib to find
the offset of the modid in the link_map structure.
Tested on x86/amd64/ppc64/s390x. Somewhat tested on ppc32 and arm64.
Untested/a few #ifdef-ed lines not compiled on arm/mips32/mips64
and darwin.
For more background info about thread local storage handling, see
'ELF Handling For Thread-Local Storage' http://www.akkadia.org/drepper/tls.pdf
Changes:
* auxprogs/getoff.c new auxilliary program to get platform specific offsets
(currently only the offset for the module id in struct link_map).
* configure.ac : check for dlinfo(RTLD_DI_TLS_MODID) needed for getoff.c
* new gdbserver_tests/hgtls, testing various types of __thread variables
* various m_gdbserver files:
- implement decoding of the QGetTlsAddr query
- for each platform: platform specific code to get the dtv
- call to external program getoff-<platform> the first time an
__thread variable is printed.

Reduce memory needed for symbols, by having the tocptr and local_ep
(used for ppc64 platforms) #ifdef-ed and accessed by macros
that becomes NOP on non ppc64 platforms.
This decreases the debuginfo memory by about 2.5 Mb on a big 32 bit application.
Note : doing that, some questions were encountered in the way
tocptr and local_ep have (or do not have) to be copied/maintained
in storage.c canonicaliseSymtab

gdbserver: introduce support to show the AVX registers.
This implies to change the interface between the
arch independent gdbserver files and the arch dependent files
as AVX implies a choice of xml files at run time.
In valgrind-low-amd64.c, the xml files and the nr of registers
are different depending on AVX support or not.
Other platforms still have a fully static nr of registers.

gdbserver: Fixes for ARM-Thumb (#214909 c 76)
fix arm thumb by transforming an address to its thumb form when needed
* added a function thumb_pc transforming a pc to its thumb form if needed
(using an heuristic to guess if this is a thumb address)
* when program counter is modified by gdb, use thumb_pc
* use thumb_pc in monitor command vg.translate
(I was able to check that this improves inferior call on a small
thumb compiled executable + mcinfcallRU test) but I could not compile
all tests with thumb).
