[input] Make a start on the new binding system Input Mapping Tables are still at the core as they are a good concept, however they include both axis and button mappings, and the size is not hard-coded, but dependent on the known devices. Not much actually works yet (nq segfaults when a key is pressed).

[console] Hook up new input system This has smashed the keydest handling for many things, and bindings, but seems to be a good start with the new input system: the console in qw-client-x11 is usable (keyboard-only). The button and axis values have been removed from the knum_t enum as mouse events are separate from key events, and other button and axis inputs will be handled separately. keys.c has been disabled in the build as it is obsolute (thus much of the breakage).

[input] Create an automatic imt switcher An imt switcher automatically changes the context's active imt based on a user specified list of binary inputs. The inputs may be either buttons (indicated as +button) or cvars (bare name). For buttons, the pressed/not pressed state is used, and cvars are interpreted as ints being 0 or not 0. The order of the inputs determines the bit number of the input, with the first input being bit 0, second bit 1, third bit 2 etc. A default imt is given so large switchers do not need to be fully configured (the default imt is written to all states). A context can have any number of switchers attached. The switchers can wind up fighting over the active imt, but this seems to be something for the "user" (eg, configuration system) to sort out rather than the switcher code enforcing anything. As a result of the inputs being treated as bits, a switcher with N inputs will have 2**N states, thus there's a maximum of 16 inputs for now as 65536 states is a lot of configuration.
