Drop setting socket non-blocking and close-on-exec. The socket is
closed soon after. Only a single packet is sent, making it almost
impossible for it to block. Also, note that sockets aren't setup this
way for IPv6.

Both of these expand to 1. However, AF_LOCAL is a Unix domain socket,
which makes no sense when reading the code.

BUG: https://bugzilla.samba.org/show_bug.cgi?id=11770
From man page of packet(7):
protocol is the IEEE 802.3
protocol number in network byte order. See the <linux/if_ether.h>
include file for a list of allowed protocols. When protocol is set to
htons(ETH_P_ALL), then all protocols are received.
Protocol argument was changed from network order to host order wrongly
in commit 9f8395cb7d.
Specifying "protocol" field to socket(AF_PACKET, ...) call only affects
the packets that are recevied. So use protocol = 0 when sending raw
packets.

Since this code does not need any private structures defined in
ctdb_private.h, protocol/protocol.h should suffice.

In Samba this is now called "tevent", and while we use the backwards
compatibility wrappers they don't offer EVENT_FD_AUTOCLOSE: that is now
a separate tevent_fd_set_auto_close() function.
This is based on Samba version 7f29f817fa.

This enhances the framework for sending tcp tickles to be able to send ipv6 tickles as well.
Since we can not use one single RAW socket to send both handcrafted ipv4 and ipv6 packets, instead of always opening TWO sockets, one ipv4 and one ipv6 we get rid of the helper ctdb_sys_open_sending_socket() and just open (and close) a raw socket of the appropriate type inside ctdb_sys_send_tcp().
We know which type of socket v4/v6 to use based on the sin_family of the destination address.
Since ctdb_sys_send_tcp() opens its own socket we no longer nede to pass a socket
descriptor as a parameter. Get rid of this redundant parameter and fixup all callers.
(This used to be ctdb commit 406a2a1e364cf71eb15e5aeec3b87c62f825da92)
