Various changes. * Makefile: svmodule.c.proto and svgen.py are gone, svmodule.c came in their stead. Also, pass -DUSE_DL flag to thread.c and give the user a possibility to add the -DDEBUG to just thread.c. * ceval.c: init_save_thread() can be called more than once now. * svgen.py, svmodule.c.proto, svmodule.c: Removed prototype file and replaced it by the generated file. * thread.c: Added some more checks; added call to DL library when it is also used to tell it where the shared arena is so that DL can use some other area. * threadmodule.c: Call init_save_thread from another place. Also, added new function getlocklock() which does to lock objects what getfilefile does to file objects.
