This includes device add and remove events, and axis and buttons for
evdev. Will need to sort out X11 input later, but next is getting qwaq
responding.
The common input code (input outer loop and event handling) has been
moved into libQFinput, and modified to have the concept of input drivers
that are registered by the appropriate system-level code (x11, win,
etc).
As well, my evdev input library code (with hotplug support) has been
added, but is not yet fully functional. However, the idea is that it
will be available on all systems that support evdev (Linux, and from
what I've read, FreeBSD).
The recent changes to key handling broke using escape to get out of the
console (escape would toggle between console and menu). Thus take care
of the menu (escape) part of the coupling FIXME by implementing a
callback for the escape key (and removing key_togglemenu) and sorting
out the escape key handling in console. Seems to work nicely
This refactors (as such) keys.c so that it no longer depends on console
or gib, and pulls keys out of video targets. The eventual plan is to
move all high-level general input handling into libQFinput, and probably
low-level (eg, /dev/input handling for joysticks etc on Linux).
