This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.

Original commit message from CVS:
* gst/gstbin.c: (gst_bin_remove_func), (update_degree),
(gst_bin_handle_message_func):
The message src can be NULL, don't try to print the object names in that
case.
* libs/gst/base/gstbasesink.c: (gst_base_sink_pad_activate):
Add some more debug info.
* tests/check/pipelines/simple-launch-lines.c: (run_pipeline),
(GST_START_TEST):
Add some debug.
Fix the test, pull based sinks go ASYNC to PAUSED, just like other
scheduling modes.

* tests/check/pipelines/simple-launch-lines.c
(test_state_change_returns): Enable pull-mode tests now that
basesink has been fixed.
* libs/gst/base/gstbasesink.c (gst_base_sink_needs_preroll):
Changed from gst_base_sink_is_prerolled, reversing the sense of
the return value. Returns FALSE also if the sink is in pull mode,
in which case it needs no preroll.
(gst_base_sink_query, gst_base_sink_change_state): Update for
needs_preroll change.
(gst_base_sink_change_state): Add a case for READY_TO_PAUSED after
chaining up, in which we return SUCCESS directly if we activated
in pull mode instead of ASYNC. Involves countering an async_start
message sent before chaining up; not sure if this is correct, in
an ideal world we only send async-start when activating in push
mode.

(test_state_change_returns): New test, partially disabled until
basesink is fixed.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
Add new element field and method.
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_init),
(bin_remove_messages), (gst_bin_add_func), (gst_bin_remove_func),
(gst_bin_recalc_state), (gst_bin_get_state_func),
(gst_bin_element_set_state), (gst_bin_change_state_func),
(gst_bin_continue_func), (bin_bus_handler),
(bin_push_state_continue), (bin_handle_async_start),
(bin_handle_async_done), (gst_bin_handle_message_func):
Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.
* gst/gstelement.c: (gst_element_init), (gst_element_send_event),
(gst_element_get_state_func), (gst_element_continue_state),
(gst_element_lost_state), (gst_element_set_state_func),
(gst_element_change_state):
* gst/gstelement.h:
Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)
Export gst_element_change_state() method so that subclasses can use it.
API: gst_element_change_state()
API: GST_STATE_TARGET
* gst/gstpipeline.c: (gst_pipeline_class_init),
(reset_stream_time), (gst_pipeline_change_state),
(gst_pipeline_handle_message), (gst_pipeline_set_new_stream_time):
Using the new ASYNC_START message we can reset the base_time when
needed. This can then be used to implement base_time redistribution in
flushing seeks so that we can remove the explicit seek handling.
Perform latency query and configuration when going to PLAYING.
* libs/gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_query), (gst_base_sink_change_state):
Post new ASYNC_START/ASYNC_DONE messages.
* tests/check/generic/sinks.c: (GST_START_TEST):
Fix test because the bin will not set the async element to PLAYING right
away.
* tests/check/gst/gstbin.c: (pop_async_done), (GST_START_TEST):
Make the message check a little stronger.
Handle ASYNC messages.
* tests/check/pipelines/cleanup.c: (GST_START_TEST):
* tests/check/pipelines/simple-launch-lines.c: (GST_START_TEST):
Expect ASYNC_DONE messages.

* tests/check/pipelines/simple-launch-lines.c
(simple_launch_lines_suite, test_tee): Disable tee test until I
have time to fix it :-(
Original commit message from CVS:
2007-02-09 Andy Wingo <wingo@pobox.com>
* tests/check/pipelines/simple-launch-lines.c (test_tee): Add
tests for push and pull tee behavior.
* plugins/elements/gsttee.h:
* plugins/elements/gsttee.c: Describe has-sink-loop better, and
mark as deprecated as well as unimplemented. It was a crack idea.
Add support for tee operating in pull mode, off by default.
Original commit message from CVS:
* tests/check/pipelines/simple-launch-lines.c: (test_stop_from_app):
Attempt to 'fix' spuriously failing test case: it seems like the
timeout of half a second is simply too small when the system is under
load otherwise, and the timeout doesn't really seem to serve any
particular purpose here. Give the pipeline a few seconds to preroll
first, and then give it another half a second to go from PAUSED to
PLAYING and marshal the message into the main thread.

* tools/gst-md5sum.c: (event_loop):
GstBusHandler -> GstBusFunc, return value has the same meaning as
any other GSource (FALSE == remove source).
_add_watch() and _add_watch_full() now take a MessageType mask to
only handle specific types of messages.
_poll() returns the GstMessage instead of the message type to avoid
race conditions.
_have_pending() takes a MessageType mask now too.
Added testsuite for multiple bus watches.
Fix testsuites and applications for new bus API.
