Original commit message from CVS:
2005-02-18  Andy Wingo  <wingo@pobox.com>

* gst/elements/gstfakesrc.c (gst_fakesrc_class_init): Add HAS_LOOP
and HAS_GETRANGE properties, readwrite + construct.
(gst_fakesrc_set_pad_functions)
(gst_fakesrc_set_all_pad_functions): New procs, like in fakesrc.
(gst_fakesrc_set_property, gst_fakesrc_get_property): Same as
fakesrc.
(gst_fakesrc_get_range_unlocked): New proc, factored out of the
core of _loop.
(gst_fakesrc_get_range): Getrange implementation for fakesink.
(gst_fakesrc_loop): Interface with get_range_unlocked.
(gst_fakesrc_activate): Add support for both activation modes,
with assertions.

* gst/elements/gstfakesink.h:
* gst/elements/gstfakesrc.h: Add has_loop and has_chain instance
variables.

* gst/elements/gstfakesink.c (gst_fakesink_class_init): Add
HAS_LOOP and HAS_CHAIN object properties, readwrite but also set
on construction.
(gst_fakesink_set_pad_functions): New proc, sets the functions on
one pad, setting the loop and chain functions properly.
(gst_fakesink_set_all_pad_functions): New proc, does
set_pad_functions on all pads.
(gst_fakesink_request_new_pad): Call set_pad_functions.
(gst_fakesink_set_property, gst_fakesink_get_property): When the
HAS_LOOP and HAS_CHAIN properties are set, reset the functions on
all pads.
(gst_fakesink_activate): Assert that the appropriate functions are
available for the activation mode.
(gst_fakesink_loop): Don't unref the buffer, chain_unlocked does
it for us.
