01d8d7d718 deprecation-guards: fixup for commit 9ff4ec3104
Remove the deprecation guards for GST_PLUGIN_DEFINE_STATIC again (even though it
is deprecated) as we use it in the tests. Remove "_" for intlinkfunc.

gpointer in public header instead.

d7f59ca0c4 pad: Deprecate GST_FLOW_IS_FATAL() and GST_FLOW_IS_SUCCESS()
The problem with both macros is, that they suggest something that isn't true.
If GST_FLOW_IS_FATAL is true, there could still be a problem for many elements
and they should stop what they're currently doing and return that value
upstream (e.g. not-linked in a parser). If GST_FLOW_IS_SUCCESS is false, it
could still be that this is "ok" for the element (e.g. not-linked for a demuxer
on a few of its pads but not all).

It's better to not have these "convenience" macros but instead let people
*think* about the handling of different flow returns, that makes sense for
their element. And we should document the expected handling of flow returns for
different classes of elements in the plugin writer's guide.

Fixes bug #628014.

5f4a965f67 gstxml: Deprecate GstXml and related functions
Pipeline serialisation to and from XML is horribly broken for all

this, to avoid frustration. See countless bug reports in bugzilla.

fcc5d783df pad: add variants of gst_pad_get_caps() that don't copy caps. Fixes #590941

8af9d58ea7 gstpad: fix gst_pad_can_link()

Make the broken implementation in gstutils static.
