Pieter Wuille bb4aab90fd net: move message conversion to wire bytes from PushMessage to SocketSendData 
This furthers transport abstraction by removing the assumption that a message
can always immediately be converted to wire bytes. This assumption does not hold
for the v2 transport proposed by BIP324, as no messages can be sent before the
handshake completes.

This is done by only keeping (complete) CSerializedNetMsg objects in vSendMsg,
rather than the resulting bytes (for header and payload) that need to be sent.
In SocketSendData, these objects are handed to the transport as permitted by it,
and sending out the bytes the transport tells us to send. This also removes the
nSendOffset member variable in CNode, as keeping track of how much has been sent
is now a responsability of the transport.

This is not a pure refactor, and has the following effects even for the current
v1 transport:

* Checksum calculation now happens in SocketSendData rather than PushMessage.
  For non-optimistic-send messages, that means this computation now happens in
  the network thread rather than the message handler thread (generally a good
  thing, as the message handler thread is more of a computational bottleneck).
* Checksum calculation now happens while holding the cs_vSend lock. This is
  technically unnecessary for the v1 transport, as messages are encoded
  independent from one another, but is untenable for the v2 transport anyway.
* Statistics updates about per-message sent bytes now happen when those bytes
  are actually handed to the OS, rather than at PushMessage time.
