Approved by:	jbeich
Pull Request:	https://github.com/freebsd/freebsd-ports/pull/565

wayland: add more mostly leaf ports to virtual category

Caveats:
- emulators/rpcs3: install qt5-wayland and ensure Renderer is Vulkan (default)
- mail/thunderbird: add MOZ_ENABLE_WAYLAND=1 via environ(7)
- www/chromium: add --ozone-platform=wayland on command line
- www/firefox-esr: add MOZ_ENABLE_WAYLAND=1 via environ(7)
- www/firefox: add MOZ_ENABLE_WAYLAND=1 via environ(7)

graphics/glew-wayland: drop X11 dependency after b44acc9409bdn

libGL is legacy GLX entry point, so maybe missing if libglvnd and/or
mesa-libs was built without X11 support.

$ make clean all deinstall install WITHOUT=X11 -C ../libglvnd
$ make clean all

graphics/glew-wayland: suggest LD_LIBMAP for session-local override

LD_LIBMAP can be limited to Wayland or KMS console e.g.,

$ cat >>~/.zshrc
if [[ ( -n $WAYLAND_DISPLAY || -z $DISPLAY ) && $LD_LIBMAP != *GLEW-wayland* ]]; then
   export LD_LIBMAP=libGLEW.so.2=libGLEW-wayland.so.2,$LD_LIBMAP
   export SDL_VIDEODRIVER=wayland,kmsdrm,x11
fi

graphics/glew: add -wayland slave

SDL_VIDEODRIVER=wayland doesn't work with current glew package while
SDL_VIDEODRIVER=x11 doesn't work using this package. So, build against
libEGL instead of libX11 and let the user decide when to use.

Tested by:	SDL (freeorion, ppsspp, renpy)
