Commit Message

session: introduce binary box.session.push

Box.session.push() allows to send a message to a client with no
finishing a main request.

Tarantool after this patch supports pushes over binary protocol.

IProto message is encoded using a new header code - IPROTO_CHUNK.
TX thread to notify IProto thread about new data in obuf sends
a message 'push_msg'. IProto thread, got this message, notifies
libev about new data, and then sends 'push_msg' back with
updated write position. TX thread, received the message back,
updates its version of a write position. If IProto would not send
a write position, then TX would write to the same obuf again and
again, because it can not know that IProto already flushed
another obuf.

To avoid multiple 'push_msg' in fly between IProto and TX, the
only one 'push_msg' per connection is used. To deliver pushes,
appeared when 'push_msg' was in fly, TX thread sets a flag every
time when sees, that 'push_msg' is sent, and there is a new push.
When 'push_msg' returns, it checks this flag, and if it is set,
the IProto is notified again.

Closes #2677
