[Bug python/10806] New: Use ensure_python_env over PyGilState_Ensure

Daniel Jacobowitz wrote about some Python/GDB experiences and bugs in the email:

http://sourceware.org/ml/archer/2009-q4/msg00008.html

This bug (and others in their own bugs) is extracted from that email to track
the issue:

* The archer branch calls PyGILState_Ensure in several places where it
should call ensure_python_env.  So python_language was often unset if
I tried 'gdb -ex "source -p file.py"'.  To work around it, I had the
end of file.py register a new gdb.Command, and called the command.

This causes a segfault when it triggers.

I've checked in a patch to archer-tromey-python. Checked FSF upstream and there
do not appear to be any other areas where PyGILState_Ensure is used.
