This change adds a keydown() function that is synchronized with events,
ie. it returns the key state as seen by previously read events.
It also completely eliminates low-level repeat events, which are not
very meaningul as the keyboard scan frequency goes up (and would be
meaningless if KEYSC interrupts were used), and adapts getkey() by
giving it access to the current driver time through pollevent().
When a key is being held and repeated, ignore other key presses
until it is released. Without this, new keys would take priority.
This is the desired behavior because pressing other keys by
accident, especially on the directional pad, is common. Besdeis
this is the system's behavior.
