  Modified files:
    sys/boot/i386/boot2  Makefile boot2.c 
  Log:
  Make both UFS1 and UFS2 fit on the same boot blocks.  These are a
  subset of Peter's patchs that are believed to be safe.
  
  Makefile tweaks:
  o -fomit-frame-pointer
  o Change default to building both UFS1 and UFS2 bootblocks.
  
  Lots of boot2 tweaks:
  o lookup is only ever called with kname, so use it directly.
  o inline memsize
  o getstr are only ever called with cmd, so hardware that.
  o tweaks to the parsing code to test after the conversion rather than
    before since we tested after anyways.
  o eliminate support for %x in printf.
  o eliminate a few bytes in printfs.
  o Tweak the boot banner.
  o eliminate support for wd and "  " devices (I might add wd back to
    keep bde happy).
  o eliminate support for a few arguments.
  
  This takes us from -162 bytes free to 67 bytes free.
  
  I've tested this only on a few systems, so be careful when updating to
  this change.
