42ada29286 Add a new client request and pair of macros,
VALGRIND_{DISABLE,ENABLE}_ERROR_REPORTING, which allow a thread to
temporarily disable reporting of errors it makes.  This is useful for
making Memcheck behave sanely in the presence of some MPI
implementations.  Also mark up libmpiwrap.c accordingly.

5e08a97bfe Make the location for temporary files configurable at runtime.
To that effect observe the environment variable TMPDIR. If defined,
its value takes precedence over VG_TMPDIR.
Because the directory name is no longer a compile time constant,
VG_(err_config_error) was changed to take a variable argument list.
Fixes #267020.

97c113e7e0 valgrind and tool mon. cmds prefixes changes + doc fixes + new vgdb option
--cmd-time-out

* changed prefixes of Valgrind core monitor commands from vg. to v.

* memcheck leak_check 'leakpossible' arg renamed to 'possibleleak'
* memcheck make_memory 'ifaddressabledefined' arg renamed to
'Definedifaddressable'
    (with uppercase D to avoid confusion with 'defined' arg).
* vgdb options
  - Some doc updates : more logical option order documentation,
       specify 'standalone' for options aimed at standalone usage.
  - added option --cmd-time-out for standalone vgdb
     (comment of Josef Weindendorfer, needed to interface with a callgrind GUI)
* updated tests according to the above.
* updated documentation according to the above.
* some additional minor doc fixes/clarifications

196c5d876c Fix safe_fd exhaustion in fork chain caused by non closing of shared_mem_fd
Patch that fixes the problem reported by Christian Borntraeger.
The problem was created by keeping the shared memory mapped file opened
without reason till the process does an exec.
In case of a chain of forked processes (without exec), the range of safe_fd
reserved for Valgrind own usage becomes exhausted.

* coregrind/m_gdbserver/remote-utils.c :
   do not VG_(safe_fd) shared_mem_fd (as it is now closed directly)
   close shared_mem_fd once file is mmap-ed and written.
* gdbserver_tests/nlfork_chain.stderr.exp,nlfork_chain.vgtest,
               fork_chain.c,nlfork_chain.stdout.exp:
     new files
* gdbserver_tests/Makefile.am:
  modified for new nlfork_chain test
