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.

The first L2CAP PDU fragment starts with the 4 octet long L2CAP header
consisting of the Length and the CID fields. The Length field doesn't
include the header itself. Thus the Length field in the BLE Data header
will be 4 octets larger than the L2CAP PDU header Length field if the
packet wouldn't be fragmented.
The current implementation doesn't correctly detect the start fragment
causing reassembly to fail as it compares the BLE Data Length with the
L2CAP Length without compensating for the header.
By increasing the L2CAP PDU Length field with the header length the
reassembly works.
Rename the variable to better reflect what length it actually
represents.

Make the time stamp precision a 4-bit bitfield, so, when combined with
the other bitfields, we have 32 bits. That means we put the flags at
the same structure level as the time stamp precision, so they can be
combined; that gets rid of an extra "flags." for references to the flags.
Put the two pointers next to each other, and after a multiple of 8 bytes
worth of other fields, so that there's no padding before or between them.
It's still not down to 64 bytes, which is the next lower power of 2, so
there's more work to do.
