Huh, finally implement writev(2) wrapper that actually works. Boys, never ever

try to use writev(2) in a non-blocking mode, especially on sockets. Not only
this makes handling of EAGAIN rather weird, but in the case of sockets makes
your code subject of a ENOBUFS, which is absolutely unclear how to handle
properly. *sigh*

Bump PORTREVISION.
