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.
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.

Meson supports building both static and shared libraries in a single
library() call. It has the advantage of reusing the same .o objects and
thus avoid double compilation.

An object that can be waited on and asked for asynchronous values.
In much the same way as promise/futures in js/java/etc
A callback can be installed for when the promise changes state.

Saves us a custom script. Template files are nicer than passing
multiline templating stuff through to glib-mkenums. And we can
get rid of our custom python script.
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.

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:

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.
