[liblo] Patch to fix TCP support pushed

Hi,

A long-awaited patch for handling buffers for open TCP streams has
been pushed!  Previously, the TCP stream did not succeed if a whole
message was not read in one shot, and the fix for this broke
non-blocking behaviour.  The correct fix is to save incomplete
messages from the stream in a buffer and append to it the next time
recv() is called.

This is one of the last important things I wanted to take care of
before 0.27, so please test.

I noticed that my hostname branch causes testlo to fail on Mac, so
I'll be looking at that next.
