Log Message:
Bootblock installer - based heavily on the alpha installboot but with
some significant differences:
 * Because the pmax bootblocks don't have a fixed load address, we
   need to keep the first stage blocks in /usr/mdec with some sort
   of executable format that includes load and transfer address.
   Since ELF is native, /usr/mdec/bootxx_* are in ELF format and
   installboot (in loadbootstrap.c) needs knowledge of the ELF format.
 * Support for installing the first stage at an arbitiary position.
   -a adds the first stage to end of the "disk" (only on works on
   regular files) and -i <block> puts the first stage at ISO
   filesystem block number <block> for use in multi-arch boot
   CDs (see installboot(8) for more details and an example).
 * No checksum support.  This should really be done in some sort of
   MI way rather than duplicating code between ports' installboot.c
