In preparation for removing the strlcat() API[1], replace its uses in
string-stream.
string_stream_vadd() appends at most a single newline into space that
was explicitly reserved when the fragment was sized, so a bounded copy
at the end of the string is enough. The return value of strscpy()
keeps the length accounting unchanged. string_stream_get_string()
concatenates a variable number of fragments into a buffer sized to
hold them all, which is what seq_buf is for.
