MEDIUM: mux-h1: Use the count value received from the SI in h1_rcv_buf()

Now, the SI calls h1_rcv_buf() with the right count value. So we can rely on
it. During the parsing, we now really respect this value to be sure to never
exceed it. To do so, once headers are parsed, we should estimate the size of the
HTX message before copying data.
