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. svn path=/trunk/; revision=25601
