* Added gmtime/localtime/mktime and SYSV timezone globals to timemodule.c.

  Added $(SYSDEF) to its build rule in Makefile.
* cgensupport.[ch], modsupport.[ch]: removed some old stuff.  Also
  changed files that still used it...  And made several things static
  that weren't but should have been...  And other minor cleanups...
* listobject.[ch]: add external interfaces {set,get}listslice
* socketmodule.c: fix bugs in new send() argument parsing.
* sunaudiodevmodule.c: added flush() and close().
