This is a more accurate name for the actual functionality than
allowEmptyInput. Historically, allowEmptyInput has allowed the server to
start with no input devices. Since 1.4 and the introduction of VCP and VCK,
there are always two input devices present.
allowEmptyInput was changed in behaviour to essentially "ignore xorg.conf
devices or not", auto-adding the built-in devices if disabled.
Rename to forceInputDevices, because that's essentially what it does. When
disabled (i.e. when hotplugging is enabled), it disables all
mouse/kbd/vmmouse devices configured in the xorg.conf file.
When enabled, it forces the traditional behaviour for input devices:
- use input devices configured in the server layout
- if none are configured, use the first pointer and the first keyboard
device in the xorg.conf
- if none are configured, create the default pointer/keyboard devices.
