Add generated add_ and remove_ for "SEQUENCE OF TType". I'm tried of
writing realloc(foo->data, sizeof(foo->data[0]) + (foo->len + 1)); Only generated for those type that is enabled by the command flag --sequence. git-svn-id: svn://svn.h5l.se/heimdal/trunk/heimdal@18005 ec53bebd-3082-4978-b11e-865c3cabbd6b
