fix: "const"-ify most of fix_fields.

Only the hf_id field in fix_fields is ever modified; This change separates out
hf_id and makes the rest of that structure "const", moving about 26 kBytes of
data from a read-write data section to a read-only data section, moving another
6 kBytes of read-write data (formerly field hf_id) to .bss -- and reclaiming
another 6 kBytes of read-write data space which was being entirely wasted due
to field packing in the struct in 64-bit builds.
