Make the MC protocol work on top of STREAM sockets

STREAM on Mac in the next commit, but I wanted to code and debug the
SOCK_STREAM version locally.

The problem with the SOCK_STREAM version is that messages are not
segmented anymore: each recv() gets everything that got posted on the
socket already, so I have to implement a buffer in which I can
reinject the extraneous bytes received, so that they can be used in
the next recv(). The real fun begins when I have half of the expected
message in buffer and the other half must be taken from the network.

Or even better: the second half was not posted yet so reading from the
network is blocking for ever. This can happen when I receive any
message in a 512-bytes buffer, but I already had a full but shorter
message in buffer. I have to try reading from the socket with the
DONT_WAIT flag, detect that there is nothing to read, and use the
