--
The proto_tree_add_item_ret_uint/int functions can be used to extract fields of
8/16/24/32 bits, but the parameter to be populated can only be a
guint32/gint32. This makes interpretation of dissector code more difficult, as
writers will be using 32-bit variables to hold fields of multiple lengths.

Propose to add 8 and 16-bit versions of the functions.
