mesa-demos: split graphics/mesa-demos into mesa-demos-misc, mesa-demos-egl and mesa-demos-glx

[tcberner]

Summary

• what it says in the title
• ports depending on graphics/mesa-demos likely only want glxinfo
• mesa-demos installs fire -- a not very good animation of a forst fire
• this breaks tab-completion to firefox -- a not very good, but still the best available browser :D

Test Plan

• Actually test it...

See also D25243. If you don't adjust dependencies proliferating packages is not very useful. For example, glxinfo, glxgears can be stripped down:

$ cd /usr/ports/graphics/mesa-demos
$ make clean patch BATCH=
$ cd $(make -V WRKSRC)/src/xdemos
$ cc -o glxinfo glxinfo.c glinfo_common.c -isystem/usr/local/include -L/usr/local/lib -lGL -lX11
$ ./glxinfo
name of display: :0
display: :0  screen: 0
direct rendering: Yes
[...]
$ cc -o glxgears glxgears.c -isystem/usr/local/include -L/usr/local/lib -lGL -lX11 -lm
$ ./glxgears

@tcberner, I've added glx-utils for glxinfo + glxgears. Do you still want to mess with mesa-demos?

[tcberner]

@jbeich No, I think in that case the ports that depend on glxinfo should just be switched to use glx-utils and mesa-demos can be left alone.

Time to abandon this.
Thanks :)
