vgdb.c contained (conditionally compiled) "invoker" code to have ptrace syscalls
used to allow gdb/vgdb to connect to a valgrind process blocked in a syscall.
This "invoker" code is ptrace based.
Not all platforms are using ptrace.
=> refactor vgdb so as allow invoker code to be added more cleanly
for non ptrace based platforms (e.g. Darwin, Solaris).
* add file vgdb.h for:
- definition of the vgdb-invoker interface
- common declarations between vgdb.c and vgdb-invoker implementations
* move ptrace related code from vgdb.c to new file vgdb-invoker-ptrace.c
* new file vgdb-invoker-none.c containing an empty invoker implementation
used on platforms that do not (yet) have a invoker implementation
(e.g. android and darwin).
* modified Makefile.am to use one of the vgdb-invoker-*.c file depending
on the platform.
* small changes related to changing ptraceinvoker to invoker in various files:
gdbserver_tests/make_local_links, gdbserver_tests/nlcontrolc.vgtest,
gdbserver_tests/mcinvokeRU.vgtest, gdbserver_tests/nlsigvgdb.vgtest
gdbserver_tests/mcinvokeWS.vgtest, coregrind/m_gdbserver/README_DEVELOPERS
Patch from Ivo Raisr, slightly modified
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@13743
--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
