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.

5eabf446b4 Fix up preload code so that on Android it doesn't try to call anything 
else -- that seems to give a runtime link failure.  In particular,
avoid calling _exit, getpagesize or __libc_freeres.

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.
* removed prefixes of Tool monitor commands
* 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

9a36fe677e Get rid of the remaining "set but not used" warnings reported by gcc 4.6 by 
swapping the roles of the VALGRIND_DO_CLIENT_REQUEST() and
VALGRIND_DO_CLIENT_REQUEST_EXPR() macros. Also, many __attribute__((unused))
declarations on variables have been eliminated. Closes #269778.

Note: so far this patch has been tested on x86/Linux, amd64/Linux and
ppc64/Linux but not yet on any other supported CPU/OS combination.
