Fixes BZ#374963.
Previously Valgrind failed to start when the executable contained
large text, data or bss segments. The load address was increased
for almost all platforms to 0x58000000 (from 0x38000000),
giving another 512 MB for the executable.

* New command line options --xtree-leak=no|yes and --xtree-leak-file=<file>
to produce the end of execution leak report in a xtree callgrind format
file.
* New option 'xtleak' in the memcheck leak_check monitor command, to
produce the leak report in an xtree file.
* File name template arguments (such as --log-file, --xtree-memory-file, ...)
have a new %n format letter that is replaced by a sequence number.

Final patch of the xtree serie, which provides the documentation.
The xtree concept was committed in the revisions
16120 : Support pool of unique string in pub_tool_deduppoolalloc.h
16121 : Implement a cache 'address -> symbol name' in m_debuginfo.c
16122 : Add VG_(strIsMemberXA) in pub_tool_xarray.h
16123 : Addition of the pub_tool_xtree.h and pub_tool_xtmemory.h modules, and of the --xtree-memory* options
16124 : Addition of the options --xtree-memory and --xtree-memory-file
16125 : Small changes in callgrind_annotate and callgrind manual
16126 : Locally define vgPlain_scrcmp in 2 unit tests
16127 : Support for xtree memory profiling and xtmemory gdbsrv monitor command in helgrind
16128 : Support for xtree memory profiling and xtmemory gdbsrv monitor command in memcheck
16129 : Update massif implementation to xtree
Some smaller follow-up patches to be expected to add some regtests,
and refine documentation.
Thanks to Ivo, Julian and Josef for the review comments.

The msg telling brk cannot be extended confuses some users
so improve the documentation and have the msg referencing the doc.

from libstdc++ when available, similar to existing __libc_freeres().
New option --run-cxx-freeres=<yes|no> can be used to change whether
this cleanup function is called or not.
Note that __gnu_cxx::__freeres() is currently available
only in gcc 6. It is not yet decided what to do about
libstdc++ from gcc 5.
Tracked under https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69945
for libstdc++.
Fixes BZ#345307 (partially).

This implements the interception of all globally public allocation
functions by default. It works by adding a flag to the spec to say the
interception only applies to global functions. Which is set for the
somalloc spec. The librarypath to match is set to "*" unless the user
overrides it. Then each DiSym keeps track of whether the symbol is local
or global. For a spec which has isGlobal set only isGlobal symbols will
match.
Note that because of padding to keep the addresses in DiSym aligned the
addition of the extra bool isGlobal doesn't actually grow the struct.
The comments explain how the struct could be made more compact on 32bit
systems, but this isn't as easy on 64bit systems. So I didn't try to do
that in this patch.
For ELF symbols keeping track of which are global is trivial. For pdb I
had to guess and made only the "Public" symbols global. I don't know
how/if macho keeps track of global symbols or not. For now I just mark
all of them local (which just means things work as previously on platforms
that use machos, no non-system symbols are matches by default for somalloc
unless the user explicitly tells which library name to match).
Included are two testcases for shared libraries (wrapmalloc) and staticly
linked (wrapmallocstatic) malloc/free overrides that depend on the new
default. One existing testcase (new_override) was adjusted to explicitly
not use the new somalloc default because it depends on a user defined
new implementation that has side-effects and should explicitly not be
intercepted.

to restrict the change to those architectures that do provide automatic
D-I coherence (x86, amd64, s390x). This commit restores the default
value for all other architectures back to its pre r15601 state, so as not
to burden those architectures unnecessarily with =all-non-file.
Also, this rewrites the relevant manual section.

or to avoid too many retranslations.

This allows to decrease memory usage when using many threads,
if no big stacksize is needed by Valgrind.
If needed (e.g. for demangling big c++ symbols), the V stacksize
can be increased.

* This option can be used to mark the begin/end of errors in textual
output mode, to facilitate searching/extracting errors in output files
mixing valgrind errors with program output.
* Use the new option in various existing regtests to test the various
possible usage.

Activating this hint using --sim-hints=no-nptl-pthread-stackcache
means the glibc nptl stack cache will be disabled.
Disabling this stack/tls cache avoids helgrind false positive race conditions
errors when using __thread variables.
Note: disabling the stack cache is done by a kludge, dependent on
internal knowledge of glibc code, and using libpthread debug info.
So, this kludge might be broken with newer glibc version.
This has been tested on various platforms and various
glibc versions 2.11, 2.16 and 2.18
To check if the disabling works, you can do:
valgrind --tool=helgrind --sim-hints=no-nptl-pthread-stackcache -d -v ./helgrind/tests/tls_threads |& grep kludge
If you see the below 2 lines, then hopefully the stack cache has been disabled.
--12624-- deactivate nptl pthread stackcache via kludge: found symbol stack_cache_actsize at addr 0x3AF178
--12624:1:sched pthread stack cache size disabling done via kludge
