Attention is currently required from: plaisthos.

Hello plaisthos,

I'd like you to do a code review.
Please visit

    http://gerrit.openvpn.net/c/openvpn/+/740?usp=email

to review the following change.


Change subject: socket: Change return types of link_socket_write* to ssize_t
......................................................................

socket: Change return types of link_socket_write* to ssize_t

This is the actual return value of send/sendto/sendmsg.
We will leave it to the single caller of link_socket_write()
to decide how to map that to the int buffer world. For now
just cast it explicitly.
