commit 45e41b7ac1eebc6b75ba4303b0b70e6f80d6ea06

    socket: avoid unnecessary bind() call
    
    Don't call bind() if the specified local address of a socket has port 0
    and the "any" address. It will be bound automatically on connect() or
    sendmsg().

    socket: add support for socket() flags
    
    On start, check if the SOCK_CLOEXEC and SOCK_NONBLOCK flags are
    supported in the socket() call and use them instead of fcntl() in order
    to reduce the number of system calls required to send a client request.

commit 4d26cfc92b878b8a90b60488361bd8cdba84903a

    socket: make all sockets non-blocking
    
    All networking code in chronyd (NTP server/client, signd client, cmdmon
    server) assumes sending a message will not block, but only the signd
    client actually checks for a write event and only the NTP server
    requests a non-blocking socket. The cmdmon server and NTP client
    (if using one socket for all servers) might be blocked.
    
    chronyc doesn't need a non-blocking socket, but it is not expected to
    block as it sends only one message at a time.
    
    Prefer dropped messages over blocking in all cases. Remove the
    SCK_FLAG_NONBLOCK flag and make all sockets non-blocking.
