[Dovecot] [PATCH] net_connect_*(): Wait for fd to complete connect(2) when fd is non-blocking

[SATOH Fumiyasu]

Hi,

Dovecot ignores EINPROGRESS on connect(2) for non-blocking fd.
This is wrong. After that, read(2) to fd (or write(2) to fd) fails
with ENOTCONN if the connection of fd is not completed.

The attached patch fixes this problem.
