Perhaps instead the setting of gdb_python_initialized should be moved to
finish_python_initialization.

Hi Tom,
I make a new patch according to your comments.
It setup gdb_python_initialized in finish_python_initialization.
I got a issue is ensure_python_env check gdb_python_initialized and throw error if it is 0.
So gdb_python_initialized to 0 will make some commands throw error when python dir has something error.
I removed this check in the patch.
This patch pass the regression test in x86_64 linux.
Please help me review it.
Thanks,
Hui
