fix the proxy functions for query_accept_caps and query_caps to use the pad
forward helper functions which correctly forwards on the internally linked pads.
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.
The idea was originally that if one passed &dest_fmt with
dest_fmt=GST_FORMAT_DEFAULT, then the code answering the query
could change dest_fmt to the actual default format used. However,
in more than half a decade of GStreamer 0.10 no piece of code in
GStreamer has ever used that feature, nor are there that many
users of this API that actually check whether the format returned
is the original format passed before using the values returned.
Also, it's just annoying-to-use API in its own right.
For all these reasons, make it so that the destination format is
passed directly and can't be changed by the element queried.
Don't mix messages and pads and tags.
Make the sink post tag messages when a tag event is received.
Since tags are sticky on pads now, they can be retrieved from there
when needed.
See #651514 for details. It's apparently impossible to write code
that avoids both type punning warnings with old g_atomic headers and
assertions in the new. Thus, macros and a version check.
This reverts commit cf4fbc005c.
This change did not improve the situation for bindings because
queries are usually created, then directly passed to a function
and not stored elsewhere, and the writability problem with
miniobjects usually happens with buffers or caps instead.
GST_DISABLE_DEPRECATED should only affect visibility of declarations in headers,
not actually remove symbols. See GitDeveloperGuidelines and DeprecatingAPI
pages in wiki.

Add new functions to clarify how the caps are compared to the template caps of
the element factory. Improve the docs to point out the difference.
