Allow OutputClass config snippets to modify the module-path.
Note that any specified ModulePaths will be pre-pended to the normal
ModulePath. The idea behind this is that any output hardware specific
modules should have preference over the normal modules.
One use-case for this is the nvidia binary driver, this allows a
config snippet like this:
Section "OutputClass"
MatchDriver "nvidia"
Modulepath "/usr/lib64/nvidia/modules"
EndSection
To get the nvidia glx specific glx module loaded, but only when the
nvidia kernel driver is loaded.
Together with the glvnd work done recently, this allows the nouveau
+ mesa and nvidia-binary userspace stacks to co-exist on the same
system without any ldconfig / xorg.conf tweaking and the xserver will
automatically do the right thing depending on which kernel driver
(nouveau or nvidia) is loaded.
