gstreamer1.0-plugins-base: Transition to meson based builds

* OpenGL packageconfigs now work differently. There are separate ones for
  OpenGL API/platform/window system selection. The meson.build script
  expects the selected ones as comma separated lists. For example, like
  "-Dgl_api=opengl,gles2". The variables OPENGL_APIS / OPENGL_PLATFORMS /
  OPENGL_WINSYS are whitespace-separated lists (which is the OE norm) of
  the respective packageconfigs. .bbappend files can then extend these
  lists with additional possible configs.
  "Possible" means that the target can support those packageconfigs. This
  does not immediately add them to the PACKAGECONFIG variable - this still
  has to be done manually. The get_opengl_cmdline_list() goes through these
  lists, and for each entry, checks if it is contained in the PACKAGECONFIG
  variable. If so, they get added to the comma separated lists that are
  passed to meson.
  For example, a Raspberry Pi layer could add "dispmanx" to OPENGL_WINSYS.

* The "ivorbis" packageconfig got renamed to "tremor", since that is the
  name of the OE recipe, and now also the name of the meson option.

* 0001-meson-build-gir-even-when-cross-compiling-if-introsp.patch and
  0002-meson-Add-variables-for-gir-files.patch are backported fixes for
  GIR support in the meson.build files.

* make-gio_unix_2_0-dependency-configurable.patch removed because it is
  no longer useful to have.

* link-with-libvchostif.patch removed because the flags it changed are
  no longer present in the meson.build scripts. If the related issue
  reappears, a similar patch can be applied again.

* 0003-riff-add-missing-include-directories-when-calling-in.patch removed
  since the entire gst riff library has been excluded from GObject
  introspection due to naming convention issues.

* Removed a number of autotool/M4 related patches and recipe lines.

* gtk-doc support is handled here, not in gstreamer1.0-plugins-common.inc,
  since unlike with autotools, only some plugin set packages use gtk-doc.

* zlib is no longer optional, and glib anyway depends on zlib, therefore
  it gets added to the DEPENDS list.

* gettext handling now part of gstreamer1.0-plugins-common.inc.

+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.
+
+See gstreamer/gstreamer#454 and gstreamer/gstreamer#381.
