[patch][python] Auto-load gdb.command and gdb.function modules

- Subject: [patch][python] Auto-load gdb.command and gdb.function modules
- Reply-to: pmuldoon at redhat dot com
This patch enables module auto-importing for the gdb.command and
gdb.function name-spaces. Any Python file (which is not __init__.py)
located in {data-directory}/gdb/python/command and
{data-directory}/gdb/python/function is now automatically imported, and
available immediately upon GDB start.
Tested on X86-64 with no regressions.
OK?
Cheers,
Phil

* python/lib/gdb/command/pretty_printers.py: Self-register
command.
* python/python.c (finish_python_initialization): Use os.path.join.
* python/lib/gdb/__init__.py: Add automatic module loading code.
Remove explicit pretty-printers.py import and registration
function.

* gdb.texinfo (Python): Document command and function module
auto-loading on start-up.
