  Don't limit key names to 4 characters
  
  Currently you can't give a key in xkb_keycodes a name of more than
  XKB_KEY_NAME_LENGTH (= 4) chars. This is a pretty annoying and arbitrary
  limitation; it leads to names such as <RTSH>, <COMP>, <PRSC>, <KPAD>
  etc. which may be hard to decipher, and makes it impossible to give
  more standard names (e.g. from linux/input.h) to keycodes.
  
  The purpose of this, as far as I can tell, was to save memory and to
  allow encoding a key name directly to a 32 bit value (unsigned long it
  was).
  
  We remove this limitation by just storing the names as atoms; this lifts
  the limit, allows for easy comparison like the unsigned long thing, and
  doesn't use more memory than previous solution. It also relieves us from
  doing all of the annoying conversions to/from long.
  
  This has a large diffstat only because KeyNameText, which is used a lot,
  now needs to take the context in order to resolve the atom.
