[PATCH 0/4 v3] Add support for static and SystemTap probes

[Sergio Durigan Junior <sergiodj@redhat.com>]

Hello,

After long days reviewing Jan's request about more abstraction, I think
I am now ready for the third submission of the SystemTap + static probes
patch.  Note that now I decided to claim that this patch series is
actually adding support not only for SystemTap, but also adding a
frontend which can theorically support any kind of static probe.

Again, the full explanation for these patches are in:

    http://sourceware.org/ml/gdb-patches/2012-03/msg00353.html

With the difference that the new commands are `-probe' (for generic
probes), `-pstap' and `-probe-stap' (for SystemTap specific probes).
Note also that if you use `-probe' with a SystemTap probe, GDB will
automagically use the SystemTap backend for it.

I really cannot remember anything more to say about this.  Again, if you
want to narrow your review, patch #2 should be the most interesting.
The doc bits have already been aproved in the last attempt, and they
were not modified since then, but I'm sending them either way.

Regtested on Fedora x86_64, no regressions.  Comments are welcome.

Thanks,
