0796586fce utils: fix the proxy functions

forward helper functions which correctly forwards on the internally linked pads.

b5c3e254b1 pad: remove getcaps and use caps query
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.

ef8ca3549e gst: fix awkward dest_format inout parameter in query utility functions
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.

3d2127f865 Revert "query: allow _make_writable on query handlers"
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.

04ebbc9f5a GstElement: Add a more flexible way to get request pads.
The new request_new_pad_full vmethod provides an additional caps field,
which allows elements to take better decision process.

Also, add a gst_element_request_pad() function to allow developers to be
able to specify which pad template they want a pad of.

Convert gstutils to use that new method instead of the old one when more
efficient.

This is useful for being able to request pads in a more flexible way,
especially when the element can provide pads whose caps depend on
runtime configuration and therefore can't provide pre-registered
pad templates.

API: gst_element_request_pad

18ecca6331 utils: speed up pad linking utility functions by not trying pads that will never work
In gst_element_get_compatible_pad(), when trying to find a compatible pad on an
element for a given pad, there's no point in checking the element's sink pads
if the pad to link is a sink pad as well, or the element's source pads if the
given pad is a source pad already, since those would never be able to link
anyway. Should speed up linking using the convenience functions a little bit,
or at least reduce debug log output.

In most places in core and baseclasses we just need the caps to do caps-
intersections. In that case ref'ed caps are enough (no need to copy).
This patch also switches the code to use the new functions.
API: gst_pad_get_caps_refed(), gst_pad_peer_get_caps_refed()

201cbbdce0 pad: flip the G_UNLIKELY
Its likely that we have caps and unlikely (error) otherwise.

82526701f0 pad: don't intersect with any in proxy_pad_get_caps
We initialize the caps with any and if a pad has NULL caps, just skip it instead
of intersecting with any. Also add branch prediction here.

8d1aeeb2af utils: Use gcc's __uint128_t for 64bit unsigned integer scaling
This is available in newer gcc releases and it should only exist
on platforms that provide some native 128bit integer arithmetic
instructions.

The x86-64 assembly for this is still kept for non-gcc compilers
that don't provide __uint128_t magic.
