ui: convert GTK and SDL1 frontends to keycodemapdb

Browse source 
The x_keycode_to_pc_keycode and evdev_keycode_to_pc_keycode
tables are replaced with automatically generated tables.
In addition the X11 heuristics are improved to detect running
on XQuartz and XWin X11 servers, to activate the correct OS-X
and Win32 keycode maps.
