  keymap: abstract a bit over the keymap format
  
  Make it a bit easier to experiment with other formats.
  
  Add a struct xkb_keymap_format_operations, which currently contains the
  keymap compilation and _get_as_string functions. Each format can
  implement whatever it wants from these.
  
  The current public entry points become wrappers which do some error
  reporting, allocation etc., and calling to the specific format. The
  wrappers are all moved to src/keymap.c, so there are no XKB_EXPORT's
  under src/xkbcomp/ anymore.
  
  The only format available now is normal text_v1.
  
  This is all not very KISS, and adds some indirection, but it is helpful
  and somewhat cleaner.
