Was only testing for handle less than next_handle, but not checking for
negative handle values. Fixed to use buffer_handle_valid() to test for a
valid handle.
- Added the apple 2 CAPS map
- auto-generate a function to check validity of a keymap index
- Added buffered message printing. This is different from keycode
buffering, since an extra delay is added for each message character to
allow polling hosts to keep up. Keycodes are generated at human speeds
and need no further slowdown.
- Added a message character delay to the arch-* modules
- enlarged the buffer pool, and created a buffer for messages
- bumped version number
