gst/gst.c: Add GST_DISABLE_OPTION_PARSING, in order to disable option parsing for embedded systems.

Original commit message from CVS:
* gst/gst.c:
Add GST_DISABLE_OPTION_PARSING, in order to disable option
parsing for embedded systems.
* gst/gstelementfactory.c:
Allow gst_element_register() to be called with plugin==NULL.
Did nobody notice that static elements were broken?
