Previous patches converted all fvalue_to_string_repr calls to expect
an allocated buffer (and not a passed in one). Now changing signature
to force an allocated buffer. Added wmem in case that can be taken
advantage of within epan (and since the function signature was changing
anyway).

Simplify use of fvalue_to_string_repr in rawshark by just having it
return an allocated string representation of a field value instead
of trying to find the right allocated buffer size to pass in.
This will also allow fvalue_to_string_repr to be converted to
exclusively return allocated strings and not accept a provided buffer.

This "fixes" a hypothetical ABI mismatch with wsutil and avoids pulling more

A nice side-effect is that libwsutil no longer depends on version.h.

The "-Wwrite-strings" flag produces nuisance warnings. These warnings are
not useful, they're impossible to fix in a sane way and therefore are being
handled with casts of static strings to (char *).
This just moves the warning to [-Wcast-qual] and a compiler pragma is
in turn required (and used) to squelch that warning.
Remove the Wwrite-strings warning. Let that responsibility fall on the
programmer (as is done by casting).
