Warner Losh ae78672c56 MFp4 (checkpoint of work in progress):
o Use a directory layout that is more akin to the i386 boot layout.
o Create a libat91 for library routines that are used by one or more
  of the boot loaders.
o Create bootiic for booting from an iic part.
o Create bootspi for booting from an spi part.
o Optimize the size of many of these routines (especially emac.c).  Except
  for the emac.c optimizations, all these have been tested.
o eliminate the inc directory, libat91 superceeds it.
o Move linker.cfg up a layer to allow it to be shared.
