Add "proto_item_set_text()", which sets the "representation" field of an

existing protocol tree item.

Add "proto_tree_add_notext()"; it's just like "proto_tree_add_text()",
but without the text, and it sets the "representation" field to NULL;
that field would be set later with "proto_item_set_text()".

Those routines let you construct, for example, an interior node of the
protocol tree whose text can't be determined until all the nodes under
it have been dissected - it's similar to "proto_item_set_len()" in that
fashion.

Use that when dissecting address TLVs in the CDP dissector - create the
item for an address in an "Addresses" TLV with no text, and then fill in
the items under it one at a time; if we get cut off before we get to the
actual address, set the text to "Truncated address", otherwise set it to
a description of the address.

Also, set the length of the item for the entire address TLV correctly.
