epan/dissectors/packet-ncp2222.inc is a bit hard to fix, so we're not
ready to enable that warning by default yet.
Throw in some casts to handle GLib routines that take arbitrary
non-const pointers (they can later return the pointers, and some
callers might want to modify or free up those pointers in cases where
they're known to be writable or allocated).
Use ep_tvb_memdup() rather than a combination of ep_alloc() and
tvb_memcpy().
Clean up some indentation.
