only.


include/my_getopt.h:
  Added u_max_value as for user definable maximum value for
  a variable in my_getopt.
myisam/myisamchk.c:
  myisamchk now uses my_getopt struct for variables also.
  Variables can be set with -O var=val, --set-variable=var=val and
  --variable=val now.
mysys/getvar.c:
  my_set_changeable_var moved to my_getopt.c
mysys/my_getopt.c:
  Added special prefix --maximum[-variable-name=...] for user
  definable maximum values for variables, among other things.
