python2-gst0.10 making patches for static packages

GST is made into a static library, while Python2 's GST has multiple libraries referencing GST in a dynamic library

So, think of a way to package the GST required by python2 into a separate shared library

The way to do this is to python2_gst all the. So first into. A

Get all the linked GST functions by nm-g and filtering

Generate a small file of these functions, referencing all of them in a static function

The small file is then compiled into so files and linked to the GST library so that the GST functions required by PYTHON2_GST are all linked in.

At the same time, the way that the GST dynamic plug-in can be added is also registered at startup, so that the package that python2_gst gets is self-contained.
