Fix some tests on ppc-debian6,s390x + handled Nick Nethercote, Josef
Weidendorfer comments
* improved testing & related doc
- added option --vex-iropt-precise-memory-exns=yes to mcsig(no)pass.vgtest
+ updated manual-core.xml
- cleanup some comments in *.vgtest
- modified filter_gdb and filter_memcheck_monitor to
handle specific ppc/debian6.0 mcsig(no)pass output
handle specific s390x 'missing debug info'
- added more information in README_DEVELOPPERS on how to
investigate failing gdbserver tests.
* handled Nick Nethercote comment:
Replaced kludgy ms.snapshot detailed
by ms.detailed_snaphot
Updated documentation and test.
* handled Josef Weindendorfer comments:
- do not report an error if ptrace_scope file can't be read.
Instead, a debug trace is done if -d (debug) option given
- added an option -l to give the list of active Valgrind
gdbserver. Useful a.o. to support callgrind_control.
Updated documentation
- added ref. to vgdb help in the vgdb --help message
