  Log:
  Clean up before implementing vfs clustering for msdosfs:
  
  In msdosfs_read(), mainly reorder the main loop to the same order as in
  ffs_read().
  
  In msdosfs_write() and extendfile(), use vfs_bio_clrbuf() instead of
  clrbuf().  I think this just just a bogus optimization, but ffs always
  does it and msdosfs already did it in one place, and it is what I've
  tested.
  
  In msdosfs_write(), merge good bits from a comment in ffs_write(), and
  fix 1 style bug.
  
  In the main comment for msdosfs_pcbmap(), improve wording and catch
  up with 13 years of changes in the function.  This comment belongs in
  VOP_BMAP.9 but that doesn't exist.
  
  In msdosfs_bmap(), return EFBIG if the requested cluster number is out
  of bounds instead of blindly truncating it, and fix many style bugs.
