Two-level index structure for FULLTEXT indexes

myisam/ftdefs.h:
  intermediate cleanup checkin
myisam/mi_create.c:
  intermediate cleanup checkin
myisam/myisamchk.c:

myisam/ft_parser.c:

mysql-test/r/fulltext.result:
  stopword test
mysql-test/t/fulltext.test:
  stopword test
mysys/mulalloc.c:
  function comments clarified
include/my_handler.h:
  get_key_length_rdonly utility macro
include/myisam.h:
  this kind of hacks bites :)
myisam/ft_dump.c:
  bugfix
myisam/mi_open.c:
  bugfix
myisam/sort.c:
  bugfixing
myisam/mi_rnext.c:
  not a solution at all, but a temporary fix to make
  mi_rnext to work on ft2 index. (only ft_dump uses mi_rnext
  on fulltext indexes for now).
