Fix 326462 Refactor vgdb to isolate invoker stuff into separate module
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
