Keymap support for QWS.

This patch adds support for keymaps to the QWSKeyboardHandler. The keymaps
can be generated by the kmap2qmap tool (see tools/ directory). The source
keymaps can be standard Linux .kmap files.

Changes to Qt:
 * completely refactored the Tty and Usb (now known as LinuxInput) handlers
 * removed the LinuxIS plugin (handled by LinuxInput now)
 * removed support for iPAQ, EBX and Zylonite keypads (obsolete hardware)
 * removed support for RAW tty mode. This could be re-added, for non-Linux
   systems by implementing a PC/AT scan-code to Linux keycode converter.

New features for Tty and LinuxInput (ex Usb) handlers:
 * support for keymaps
   QWS_KEYBOARD=..:keymap=/path/to/x.qmap:..
 * support for dead keys and the compose key
 * support for lock LEDs
 * support for key repeat rates (in ms):
   QWS_KEYBOARD=..:repeat-delay=x:repear-rate=y:..
 * the default keymap supports latin1 composing via AltGr:
   QWS_KEYBOARD=..:enable-compose:..
 * ctrl+alt+backspace application zapping can be disabled:
   QWS_KEYBOARD=..:disable-zap:..
 * added virtual filter functions to both the Tty and the LinuxInput
   handlers. (QWSKeyboardHandler::processKeycode should be virtual in the
   first place, but that would be BIC)

Still missing:
 * extended documentation for QWS_KEYBOARD
