[OPTIM] stream_sock: avoid fast-forwarding of partial data

Fast-forwarding between file descriptors is nice but can be counter-productive
when only one part of the buffer is forwarded, because it can result in doubling
the number of send() syscalls. This is what happens on HTTP chunking, because
the chunk data are sent, then the CRLF + next chunk size are parsed and immediately
scheduled for forwarding. This results in two send() for the same block while a
single one would have done it.
