Deprecate ports broken for more than 6 months

- Update `graphics/embree' to the latest version 3.8.0 (unfortunately,
  the new API is not backward compatible with the version 2 API; this
  was required to remove various deprecated API functions that had
  accumulated over time, fix suboptimal design decisions and mistakes,
  clean up inconsistent naming, increase flexibility, etc.
- Install tutorials as port examples; install documentation files into
  the standard location instead of overriding the default DOCSDIR
- Drop no longer used `graphics/ImageMagick' dependency: BMP, GIF, PNG,
  TGA, and TIFF formats are handled by the OpenImageIO now, but it is
  somewhat heavy dependency and is disabled upstream by default, so do
  the same (au contraire, JPEG and PNG are enabled unconditionally as
  being backed by very common and light packages)

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Convert Python ports to FLAVORS.

  Ports using USE_PYTHON=distutils are now flavored.  They will
  automatically get flavors (py27, py34, py35, py36) depending on what
  versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils
  but need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
  added to cope with Python ports that did not have the Python
  PKGNAMEPREFIX but are flavored.

  USES=python now also exports a PY_FLAVOR variable that contains the
