Change x11/xorgproto to become a build dep

Change x11/xorgproto to become a build time dependency when added to
USE_XORG.  Change the dependency to be on the port, rather than a file the
port installs.
Fix fallout.
Bump portrevision on depending ports.

Unbreak the build against Clang 6.0.0 (adheres to C++14 by default).

PR:	224989

- Update LuxRender modern (Embree-based) branch to version 1.6
- Move DISTFILES setting back to master port exclusively as upstream had
  used correct (coherent with v1.4) tags for v1.6 this time
- Register mutual port install-time conflict (CONFLICTS_INSTALL)
- Create convenience symlink in `post-extract' rather than `pre-patch',
  because `200:dos2unix' bogusly(?) runs before `300:pre-patch'
- Since luxrays' library samples are not built as of r410138, do not try
  to patch them (GC currently no-op patches)
- For the same reason, do not request GLUT, GLEW, and execinfo libraries
  that were only used when building samples
- Convert FreeImage to an option (mandatory for v1.4) and default to off

- Update to version 1.5.1 which fixes a few annoying issues with glossy
  materials when using the new LuxCore rendering modes
- Because upstream did not use different tag names for LuxCore and LuxRender
  this time, avoid distfile name clash by using .tar.gz format for smaller
  distfile (3.1M) and .tar.bz2 for the larger one (28M)
- Ensure that correct build number is reported in the "About" dialog box
- Fix USES and DISTVERSION check for version 1.4 support while I'm here

Remove hyphen from PKGNAMESUFFIX: originally Makefile was copied from an
`x11/nvidia-driver' slave port where it makes sense because dashed number
is actually a major version.  Here this suffix is "dedotted" full version
and used purely to give the package unique name.  This logic follows our
existing `multimedia/ffmpeg0' and `devel/subversion*' ports, for example.

Update LuxRender to version 1.5.  As it now requires `graphics/embree'
which is not available on 9.X for the moment, preserve version 1.4 as
`graphics/luxrender14' slave port.
