Alan Modra c94cb02662 HOWTO size encoding
This changes the HOWTO macro to encode the howto.size field from a
value given in bytes.  This of course requires editing all target
uses of HOWTO, a major pain, but makes it a little nicer to specify
new target HOWTOs.  Object files before/after this patch are
unchanged in .data and .rodata.
