Fix T51153: Video duration is detected wrong after FFmpeg update

The issue was caused by stupid workaorund for libav. Now things works for
FFmpeg. There might need some tweaks needed for Libav, but that one is
not really priority for support.

Fix memleak in previous hair commit

Merge branch 'master' into blender2.8

Startup.blend: set EEVEE as the default engine

The original idea was to use Clay as the default. But since clay may not
even be in the final release, we can't afford to have a startup.blend
that doesn't deliver a reliable result regardless of build options.

Use static assert in Clay engine to ensure struct alignment

Some minor cleanup.

Fix again DwM bbones drawing.

Stupid mistake in rB6824ee0595c9dd7d1c18864f2 fix, again reported by
@campbellbarton, thanks.

Mesh Center: improved center-of-mass calculation

Previous method was based on face-area, giving un-even results
based on topology and gave issues with zero area faces.

This method gives matching results for concave ngons and the same geometry triangulated.

UI: Add template_search (version of template_ID for non-IDs)

Adds a version of template_ID that can be used for non-ID properties.
The property to search for and the collection to search in has to be
passed to it.
Like template_ID it also takes arguments to define a 'new' and 'unlink'
operator. They will be displayed as icon-only buttons then.
Also added a version that can display preview thumbnails.

Had to do some additional changes to make text-buttons support
displaying/modifying empty RNA properties.

This will be needed for workspaces, see D2451.

Force core profile as main profile

This removes a few options from CMake:
* WITH_LEGACY_OPENGL
* WITH_GL_PROFILE_COMPAT
* WITH_GL_PROFILE_CORE

We still have WITH_GL_PROFILE_ES20. So you can still alternate between
ES20 and CORE profile (when es20 is disabled).

If you want to explicitly see the stubs errors just define
WITH_LEGACY_OPENGL.
