John Baldwin acbf8a8d4a - Change the lookup() function to report success or failure using the carry
flag rather than explicitly halting if a lookup failed.
- Add a loop around the call to lookup() to traverse an array of
  nul-terminated strings for possible paths to the boot loader.  A double
  nul character denotes the end of the list.
- Add a new message to say that the boot failed if all of the path lookups
  for a boot loader file failed.
- Add '/boot/loader' as a second boot path.  If you build an ISO using
  risky options to mkisofs such as -U then the loader will be called
  '/boot/loader' rather than '/BOOT/LOADER;0'.  This allows cdboot to work
  with such risky ISO images.
- Bump version to 1.2 to denote added functionality.

The basic idea as well as some of the code were provided by the submitter,
but I added some extra code to use a loop rather than hard-code just 2
possible paths.
