Add new GST_API_EXPORT in config.h and use that for GST_*_API

we're using -fvisibility=hidden or not, so it's better to set it
to the right thing directly than hard-coding a compiler whitelist
in the public header.

We put the export define into config.h instead of passing it via the
command line to the compiler because it might contain spaces and brackets
and in the autotools scenario we'd have to pass that through multiple
layers of plumbing and Makefile/shell escaping and we're just not going

users of the lib headers, so it's not a problem to put it into config.h

building it, otherwise import the API from the headers.

This fixes linker warnings on Windows when building with MSVC.

The problem was that we had defined all GST_*_API decorators
unconditionally to GST_EXPORT. This was intentional and only
supposed to be temporary, but caused linker warnings because
we tell the linker that we want to export all symbols even
those from externall DLLs, and when the linker notices that
they were in external DLLS and not present locally it warns.

What we need to do when building each library is: export
the library's own symbols and import all other symbols. To
this end we define e.g. BUILDING_GST_FOO and then we define
the GST_FOO_API decorator either to export or to import
symbols depending on whether BUILDING_GST_FOO is set or not.

by this we at least pass them through correctly then.

accumulated together with the values of the non-live first pad,

This reverts commit 11e0f451eb498e92d05d8208f7217625dc62848b.

When pushing a sticky event out of a pad with a pad probe or pad offset,
those should not be applied to the event that is actually stored in the
event but only in the event sent downstream. The pad probe and pad
offsets are conceptually *after* the pad, added by external code and
should not affect any internal state of pads/elements.

Also storing the modified event has the side-effect that a re-sent event
would arrive with any previous modifications done by the same pad probe
again inside that pad probe, and it would have to check if its
modifications are already applied or not.

For sink pads and generally for events arriving in a pad, some further
changes are still needed and those are tracked in
