2020-06-19Fix the type of arrays of pointers to hf_ values for bitfield routines.Guy Harris1-25/+25
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.

2017-01-10Rename tvb_new_subset() to tvb_new_subset_length_caplen().Guy Harris1-1/+1
This emphasizes that there is no such thing as *the* routine to construct a subset tvbuff; you need to choose one of tvb_new_subset_remaining() (if you want a new tvbuff that contains everything past a certain point in an existing tvbuff), tvb_new_subset_length() (if you want a subset that contains everything past a certain point, for some number of bytes, in an existing tvbuff), and tvb_new_subset_length_caplen() (for all other cases). Many of the calls to tvb_new_subset_length_caplen() should really be calling one of the other routines; that's the next step. (This also makes it easier to find the calls that need fixing.)
