waylandsink: Implement XDG-shell stable support [wl_shell] is officially [deprecated], so provide support for the XDG-shell protocol should be provided by all desktop-like compositors. (In case they don't, we can of course fall back to wl_shell). Note that the [XML spec] is provided by the `wayland-protocols` git repository, which is provided by the Wayland project. Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/897 [wl_shell]: https://people.freedesktop.org/~whot/wayland-doxygen/wayland/Client/group__iface__wl__shell.html [deprecated]: https://github.com/wayland-project/wayland/commit/698dde195837f3d0844b2725ba4ea8ce9ee7518c [XML spec]: https://github.com/wayland-project/wayland-protocols/blob/master/stable/xdg-shell/xdg-shell.xml

Add feature options for almost all plugins The only plugins remaining are those that haven't been ported to Meson yet, and msdk. Also, the tests are still automagic. https://bugzilla.gnome.org/show_bug.cgi?id=795107

libs: fix API export/import and 'inconsistent linkage' on MSVC 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. While we're at it, 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. https://bugzilla.gnome.org/show_bug.cgi?id=797185

meson: Maintain macOS ABI through dylib versioning Requires Meson 0.48, but the feature will be ignored on older versions so it's safe to add it without bumping the requirement. Documentation: https://github.com/mesonbuild/meson/blob/master/docs/markdown/Reference-manual.md#shared_library

build: Fix build on systems with wayland-client headers in non-default location Add a missing dependency to wl_client_dep for the wayland build. Some distros have the wayland-client headers not installed in /usr/include (which is perfectly valid, the pkg-config .pc file gives the right feedback).
