gstreamer1.0: Transition to meson based builds

Update gstreamer to meson build system.

This update follows the strategy and description provided in commit
[3e71919b865433ca007bf23f9b4f9015e25ac04e] from upstream.

Autotools patches are completely dropped from the layer, and
meson-relevant patches are introduced instead.

+Subject: [PATCH] meson: build gir even when cross-compiling if introspection
+ was enabled explicitly
+
+This can be made to work in certain circumstances when
+cross-compiling, so default to not building g-i stuff
+when cross-compiling, but allow it if introspection was
+enabled explicitly via -Dintrospection=enabled.
+
+Fixes #454 and #381.
