Using gst_pad_proxy_get_caps() breaks backwards compatibility with old
parsers because it will propagate the other side's fields like "parsed"
and "framed" and also breaks parser/converters.
Fixes bug #664221.
In 0.10, this can be done with a one-liner by using GST_BUFFER_DATA/SIZE with
put_data. A 0.11 user has to resort to gst_buffer_map, which is less convenient
and might require a memcpy internally.
API: gst_byte_writer_put_buffer()
Fixes compiler warnings on OSX:
gstadapter.h:82: warning: type qualifiers ignored on function return type
gstadapter.c:412: warning: type qualifiers ignored on function return type
const gpointer is not the same as gconstpointer or const void *.

Add the pad mode to the activate function so that we can reuse the same function
for all activation modes. This makes the core logic smaller and allows for some
elements to make their activation code easier. It would allow us to add more
scheduling modes later without having to add more activate functions.
Turns some boolean arguments in the scheduling query to flags, which are easier
to extend and makes the code easier to read.
Make extra methods for configuring and querying the supported scheduling modes.
This should make it easier to add new modes later.
Remove the getcaps function on the pad and use the CAPS query for
the same effect.
Add PROXY_CAPS to the pad flags. This instructs the default caps event and query
handlers to pass on the CAPS related queries and events. This simplifies a lot
of elements that passtrough caps negotiation.
Make two utility functions to proxy caps queries and aggregate the result. Needs
to use the pad forward function instead later.
Make the _query_peer_ utility functions use the gst_pad_peer_query() function to
make sure the probes are emited properly.
Don't rely on the return value of a vmethod to trigger the default
implementation but make a real defaul implementation of the method that the
subclass can chain up to.
Make a default implementation of the transform_caps vmethod so that subclasses
can call into it.
Make a default implementation of transform_size.
Avoid doing something in the vmethod trampoline.
The fixate caps function was not used externally and we have vmethods in the
base classes where it is needed.
Update some docs.
simplify some fixate functions in the base classes. Also pass the untruncated
caps to the vmethod.
