Store connections in tcp-passive to allow sending
In the case of TCP-ACTIVE, we don't have a problem, because the new

is no peer reflexive candidates, so once the pair is selected, the local

them to the child connections

Data and STUN messages sent over TCP MUST follow the framing method
specified in [RFC4571] section 2. We will frame every outgoing packet
and split it into 62KB frames when sending, and on reception, we will
unframe the rfc4571. For now, we only unframe for udp-turn tcp-act/pass
candidates, which means only for MS-TURN over TCP.

Add a nice_socket_send_reliable API for internal use.
One issue with tcp-bsd is that it will queue messages when the tcp socket
is not writable, but it will also drop messages when the queue is full.
If we want to do proper reliable ice-tcp, we need to make sure that
messages don't get dropped, also, this would affect http/socks5/pseudossl
if their messages get dropped. For ice-tcp, when the socket is not writable
we want to return 0, not queue the message.
The change here is to allow connchecks and other important protocol messages
to be sent as 'reliable' on tcp transports by queuing them and in the various
socket layers and to never drop them, but all user messages will be dropped.
