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
