media-libs/opensubdiv: Version bump to 3.4.3

Version bump to media-libs/opensubdiv-3.4.3

This version has been updated to EAPI 7 and inherits from cmake rather
than cmake-utils. The license has been corrected to modified apache-2

New USE flags are added to control installation of the docs, examples
and tutorials. The build system is patched to install the tutorials
into /usr/bin, and to use python 2.7 to build the documentation. The
latter fixes bug 722570 for this ebuild.

When using FEATURES="test", the basic and regression tests are enabled.
However the GLTESTS are disabled as portage does not have access to an
X11 display to run them during the build.

A direct dependency on libXinerama was added as this is no longer
included by glfw for wayland users. This fixes bug 708160 for this
ebuild.

For cuda users, the build will fail when using GCC 9+. If an incorrect
version is selected, the ebuild will warn the user to run gcc-config.

Others have found that cuda kernels fail to build with multiple jobs
for previous versions of opensubdiv. I use MAKEOPTS="-j1" to prevent
this, although it has not been an issue for me.
