Added my_getopt struct and modified myisamchk to the bk tree.

include/Makefile.am:
  Added my_getopt.h
myisam/myisamchk.c:
  myisamcheck is using my_getopt struct now. Old code left:
  changeable_var[], will be changed later.
mysys/Makefile.am:
  added my_getopt.c
mysys/getvar.c:
  Added my_set_changeable_var. This is not being used yet, and
  is mostly a copy of set_changeable_var still.
BitKeeper/etc/logging_ok:
  Logging to logging@openlogging.org accepted
