Guy Harris e1d9a226a2 Fix the type of arrays of pointers to hf_ values for bitfield routines. 
The static arrays are supposed to be arrays of const pointers to int,
not arrays of non-const pointers to const int.

Fixing that means some bugs (scribbling on what's *supposed* to be a
const array) will be caught (see packet-ieee80211-radiotap.c for
examples, the first of which inspired this change and the second of
which was discovered while testing compiles with this change), and
removes the need for some annoying casts.

Also make some of those arrays static while we're at it.

Update documentation and dissector-generator tools.
