ChangeLog, mke2fs.8.in, mke2fs.c, tune2fs.8.in, tune2fs.c, util.c, util.h:
  ke2fs.8.in, tune2fs.8.in: Change man paegs to document that the
  journal must be bewteen 1024 and 10,240 file system blocks.
  mke2fs.c, tune2fs.c: Change to use figure_journal_size()
  util.c, util.h (figure_journal_size): Change journal_default_size into
  	routine which also converts the requested journal size into filesystem
  	blocks and does bounds checking to make sure the journal is sized
  	reasonably.  Renamed function to journal_default_size.
  	parse_journal_opts): Remove bounds check for the journal size, since
  	this is now done in figure_journal_size, and based on the number of
  	filesystem blocks, as opposed to using the absolute size of the
  	journal.
