The 32-bit integer at the beginning of a context_handle is called

"context_handle_attributes" in the DCE RPC 1.1 "nbase.idl".  Rename our
structure member accordingly.

Note in a comment that we should perhaps display a context_handle as the
attributes and UUID.

Use "proto_tree_add_item()", not "proto_tree_add_bytes()", to put the
context handle raw data into the protocol tree.
