To make sure the value is only expanded/used once, in case
there are side effects to it, and to avoid calculating it
or looking it up multiple times if there is a calculation
or lookup involved.
MSVC warns on this and the documentation about the warning says:
> The compiler assumes the function returns a value of type int
which is a little scary, so lets just remove the unnecessary 'return'

Introduce a new operator ':' - e.g. element1 ':' element2
For example, 'uridecodebin : encodebin' -
if the encodebin has multiple profiles compatible with the
decodebin, multiple links will be created.
With '!' , after one delayed link is successfully done, the
pad-added callback is disconnected.

Implement GstDynamicTypeFactory as a new registry feature.
GstDynamicTypeFactory provides a way of registering a GType
into the registry, such that it will be registered as a dynamic
type when the registry is loaded, and then automatically loaded
if the type is needed during caps parsing.
This allows using non-core types in pad templates, by loading a
registry feature to create the GType on the fly.

It's useful to be able to set a name pattern for GST_DEBUG_FILE so that
the same environment variable can be used for multiple processes and
still write to different files. Especially useful if these processes
run simultaneously.
%p: Replaced with PID
%r: Replaced with random number
%p is obviously useful. %r is useful when for instance running two
processes with same PID but in different containers.

Enable it to prevent sending reconfigure when linking elements.
Useful for autoplugging when we know caps or bufferpools shouldn't change
to save doing caps renegotiation to end up with the same final scenario.
The no-reconfigure is not a proper check, it is a flag. It is implemented
as a GstPadLinkCheck to avoid creating another gst_pad_link variant.

Fixes xgettext warnings when doing 'make update-po':
gst/parse/grammar.y:217: warning: Empty msgid. It is reserved by GNU gettext:
gettext("") returns the header entry with
meta information, not the empty string.
This flag is to indicate to child elements that they can add and
remove pads at any point in time without re-adding existing ones.
Elements should post before-hand a GST_MESSAGE_STREAM_COLLECTION

When we get GST_ITERATOR_RESYNC, we need to call gst_iterator_resync()
otherwise we will always get GST_ITERATOR_RESYNC (and that loop would
run forever).
gst/gstprintf unit test would fail on 32-bit x86 with:
gstprintf.c:83:printf_I32_I64:0: 'str' (64-bit x value = b5a6978f) is not equal to '"64-bit x value = f1e2d3c4b5a6978f"'
This reverts commit cfc565e2d8.
The commit was redundant since gst_gen_sources already contains
gstenum_h. We're still investigating why some people are still seeing
a racy build failure.
This forces gstenumtypes.h to be built whenever something uses gst_dep
as a subproject dependency. This is needed since gst/gst.h includes
gstenumtypes.h
Closes https://github.com/mesonbuild/meson/issues/714 which is not
actually a Meson bug.
Earlier we were only using __declspec(dllexport/import) when we were
built with MSVC because when built with MinGW and linking with MinGW we
don't need it (and we get linker errors because of it).
However, when we're built with MinGW and someone wants to link to us
with MSVC, we still need the prototypes to have __declspec(dllimport)
since MSVC cannot do auto-import like GCC can.

When using seek_simple() in combination with other kinds of seeks, this
becomes problematic. seek_simple() does not reset the stop position to
GST_CLOCK_TIME_NONE but keeps whatever a previous seek did. So for example
when doing a seek_simple() after a rate=-1 seek, we would usually get
assertions that start>stop (and stop being the old stop from the rate=1 seek).
