When doing CPU Access, some architecture may require caches to be
synchronize before use. Otherwise, some visual artifact may be
visible, as the CPU modification may still resides in cache.

gudev/gudev.h is included unconditionally, so only enable
the gbm backend if gudev was actually found. This also
matches the meson build behaviour.
Should fix build on GNOME SDK builder.
We can pass string constants here to g_strdup_printf(),
so do so and re-enable the -Wformat-nonliteral warning
we had to disable when merging the opengl libs.
The AM_CONDITIONAL always need to be evaluated, regardless of
whether we are building with or without gl plugins (the actual
checks are only called in AG_GST_GL_PLUGIN_CHECKS).
Tests and documentation will follow separately.
The mixer elements in the opengl plugin need to stay
in -bad for now since they use GstVideoAggregator.

This makes sure that we only build files that need explicit SIMD support
with the relevant CFLAGS. This allows the rest of the code to be built
without, and specific SSE* code is only called after runtime checks for
CPU features.

* decodebin3 and playbin3 have the same purpose as the decodebin and
playbin elements, except make usage of more 1.x features and the new
GstStream API. This allows them to be more memory/cpu efficient.
* parsebin is a new element that demuxers/depayloads/parses an incoming
stream and exposes elementary streams. It is used by decodebin3.
It also automatically creates GstStream and GstStreamCollection for
elements that don't natively create them and sends the corresponding
events and messages
* Any application using playbin can use playbin3 by setting the env
variable USE_PLAYBIN3=1 without reconfiguration/recompilation.
