[RFC/RFA] new command: maintenance print target-stack

Hello,
While working to "auto-solib-add", I found that I was very frequently
in need to dumping the current target stack (I just need the names),
to see if the multi-thread layer has been pushed or not. So I
implemented a new "maintenance" command, hoping that others might
find it useful.
(gdb) maintenance print target-stack
The current target stack is:
- multi-thread (multi-threaded child process.)
- child (Unix child process)
- exec (Local exec file)
- None (None)
Opinions? Eventually, we might want to actually dump more
information if that's useful to others, but that's a start.

* target.c (maintenance_print_target_stack): New function.
(initialize_targets): Add new "maintenance print target-stack"
command.
Tested on x86-linux just to make sure, no regression. I will of course
provide documentation for this if the idea is accepted.
