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).

In many parts of the code we raise streaming error when the flow
goes wrong, and each time we create more or less similare error
message. Also that message does not let the application know what
has actually gone wrong. In the new API we add a "flow-return" detail
field inside the GstMessage so that the application has all the information
if it needs it.
API:
GST_ELEMENT_FLOW_ERROR

We only use GST_EXPORT consistently when building with MSVC by using the
visual studio definitions files (win32/common/*.def), so always disable
it when building with Autotools and only enable it with Meson when
building with MSVC.
This allows you to use MinGW to link to a GStreamer built with MSVC and
get the correct function prototypes to find functions and variables in
DLLs.
Fixes g-i warning "Gst: Constructor return type mismatch
symbol='gst_element_message_new_details' constructed='Gst.Element'
return='Gst.Structure'".
This is a newly-added function in git that has not been in a stable
release yet, so it's fine to rename it. It's also only used indirectly
via macros.

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded
... and many more. For more details see:
http://blog.nirbheek.in/2016/05/gstreamer-and-meson-new-hope.htmlhttp://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html
Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.
