4375e998ee Fix casts in a bunch of inline functions to maintain correct const-ness
Make code including GStreamer headers compile with -Wcast-qual by
maintaining const-ness when casting. Also fix function signature of
gst_byte_writer_set_pos(): the byte writer should not be marked as
const.

db79dd88c3 message: don't use typechecking cast macros
Simply use casting macros for accessing the message fields like we do for
buffers and events. Avoids some costly typechecking that does not really buy us
much.

136cfb3bed Convert unref/copy functions of GstMiniObject subclasses to static inline functions
unref and copy functions are sometimes used as function
pointers for example in the case of g_hash_table_new_full
as a GDestroyNotify function.

Currently GstBuffer, GstEvent, GstMessage and GstQuery
define their respective unref and copy functions as
macros, making use of gst_mini_object_unref/copy.
This approach works very well for most cases, except
for some automatically generated bindings (currently Vala),
where the memory management semantics are defined
declaratively.

The possible solutions would be to either convert all
the macros into static inline function, or change the
signature of gst_mini_object_unref to take a void*
instead of a GstMiniObject*.

Fixes bug #572480.

4b986a4a94 Add message to request a state change
Add a GST_MESSAGE_REQUEST_STATE that can be posted by element when they would
like to have the application change the state of the pipeline. the primary use
case is to pause the pipeline when an audio mixer is mixing a higher priority
stream but it can also be used for other purposes.

Add some docs and a unit test.

Implement the REQUEST_STATE message in gst-launch.
