[PATCH 00/13] script language API for GDB

[Doug Evans <xdje42@gmail.com>]

Hi.

My patch set to add a scripting API to GDB is ready for submission.
It sets things up so that adding Guile scripting is straightforward.
I've cc'd guile-users to apprise them of my progress.
I'll spare them the actual set of patches here,
though I plan to cc them when submitting the Guile port,
their input will be helpful.
The actual Guile port is ready ... just have some more docs to write. :-)

This patch set also has a nice effect of formalizing the interface from
GDB to Python (one aspect of which is that it removes the need for
a lot if #ifdef HAVE_PYTHON's, and it removes all the little stubs that
had to be provided when GDB was compiled --without-python).

The main patches are 02 and 03.
02 adds scripting.c, scripting.h, and scripting-priv.h.
03 updates python.c, python.h, and python-internal.h.
The rest are pretty-straightforward.

A lot of the change is mechanical:
- I want to have each ops "method" named ${lang}_${method_name}.
- Plus I want to have each API entry point have something in its
  name that says "I am a scripting API entry point".
  My first attempt used slang_ but that was thought to have
  to much potential confusion with the slang scripting language.
  Instead I've taken a minimalist approach and added "script"
  to the function name.
  E.g., apply_val_pretty_printer -> apply_val_script_pretty_printer
- Then I needed to move the interface enums defined in python.h
  out and make the values have non-python-specific names.

I'm going to wait until after 7.7 has been branched
before checking anything in of course.
