Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means
we no longer need the macro there, but for most types in core we don't
want to break ABI, which means it's better to just keep it like it is
(and use the `#ifdef` instead).

With this, gstreamer builds with -Werror on MinGW
Without this bindings get confused about the meaning of references, and
we really own these references if they are not already owned by
something else.
We won't be able to do ASSERT_CRITICAL, but the main body of the tests
are still valid, and given we ship GStreamer with this configuration, it
is important to be able to run some tests against it.
By moving the functionality down to the testclock, the implementation
no longer needs to poll the waits, but rather wait properly for
them to be added.
The performance-hit here would be that by polling the test-clock
regularly, you would create contention on the testclock-lock, making code
using the testclock (gst_clock_id_wait) fighting for the lock.
Otherwise we try to build a shared lib when we build the rest
of GStreamer statically, which won't work because we pass
-DGST_STATIC_COMPILATION when building statically, which means
we won't dllimport public symbols from our libs which means
that on Windows the unit tests will fail to link to libgstcheck.

Add new GST_API_EXPORT in config.h and use that for GST_*_API
decorators instead of GST_EXPORT.
The right export define depends on the toolchain and whether
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
to be *that* lucky.
The export define is only used if we're compiling our lib, not by external
users of the lib headers, so it's not a problem to put it into config.h
Also, this means all .c files of libs need to include config.h
to get the export marker defined, so fix up a few that didn't
include config.h.
This commit depends on a common submodule commit that makes gst-glib-gen.mak
add an #include "config.h" to generated enum/marshal .c files for the
autotools build.

For each lib we build export its own API in headers when we're
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.
That way external users of each library API automatically
get the import.

Make our own deprecation marker for libgstcheck,
since the function declaration must contain the
right API export decorator (GST_CHECK_API) and
not the one for GStreamer core.
Instead, use -fvisibility=hidden and explicit exports via GST_EXPORT.
This should result in consistent behaviour for the autotools and
Meson builds where this is done already, and will allow us to drop
the win32 .def files.
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.
Convenience function to just grab all pending data
from the harness, e.g. if we just want to check if
it matches what we expect and we don't care about
the chunking or buffer metadata.

Fixes in user code:
undefined reference to `gst_harness_add_element_sink_pad'
Also reorder harness function list to be strictly in alphabetical order and
double check the list with:
awk '{ if ($1 !~ /#define/) if ($2 ~ /gst_harness_/) { print $2 }; if ($3 ~ /gst_harness_/) { print $3} }' libs/gst/check/gstharness.h | sort
Need to define CK_DLL_EXP to extern as well in libcompat.h
which gets included before the internal-check.h where the
other fallback definition for CK_DLL_EXP is.
duplicate symbol _check_minor_version in:
libcheckinternal.a(libcheckinternal_la-check.o)
libcheckinternal.a(libcheckinternal_la-check_log.o)
Have to modify libcheck header a bit to avoid warnings
about duplicate 'extern extern'.
Also needs some additions to the libcheck meson.build file
to define CK_EXP_DLL when building the static libcheck.
This is something bindings can't handle and it causes leaks. Instead
move the ref_sink() to the explicit, new() constructors.
This means that abstract classes, and anything that can have subclasses,
will have to do ref_sink() in their new() function now. Specifically
this affects GstClock and GstControlSource.

gst_harness_new_parse() returns without any error even if it doesn't
find the specified element. Then a succeeding call to
gst_harness_set_sink_caps_str() causes an error like this:
Unexpected critical/warning: gst_pad_push_event: assertion 'GST_IS_PAD (pad)' failed
This is a bit cryptic and doesn't give users any clue what was going
on.
gst_harness_new_parse() calls gst_harness_add_parse() with a newly
created empty harness and the given pipeline description string, but
gst_harness_add_parse() does not have a way to propagate the error
back to the caller. Since the function, gst_harness_add_parse(), is a
public API, it's not a good idea to change its signature. This patch,
instead, makes the function to g_error() when it discovers any error.
With this change the same error prints:
** (myelement-test:25345): ERROR **: Unable to create pipeline 'bin.( myelement )': no element "myelement"
The current implementation of gst_parse_launch_full() doesn't return
partially constructed pipeline when GST_PARSE_FLAG_FATAL_ERRORS is
specified, however, this patch also adds a check for it.

New API functions to filter log messages before they are processed by
GstCheck. This can be used to discard specific messages that are
accepted by the test or to add callbacks that test specific messages.
Default bevavior when no callback is given to a filter is to discard the
message, because it does not makes sense to have a filter with no
callback which does not discard; that would be a noop.
Discarded messages will in addition to bypass the GstCheck handling also
return to GLib that the message is not fatal if it occurs.
