Wrote down more of the protocol.
Padding support has been added and implemented which will make it
possible for us to pad packets to mitigate length related attacks.

Messenger now works with the new net_crypto api.
...
Added callbacks in net_crypto for the data packets and status changes.
Added onion_getfriend_DHT_pubkey to onion_client.
Net crypto isn't done yet so connections between toxes are not
lossless, this means file sending is broken hence why the test fails.

Major protocol changes, this commit breaks all network compatibility.
...
Removed a bunch of useless space from various structs.
pack_nodes() and unpack_nodes() are now used to transmit lists of
nodes for the DHT and onion parts. They provide a way to transmit
both ipv6 and ipv4 nodes in the same packet in a portable way that
takes as little space as possible without compression.
Using pack_nodes, merged the send nodes and send nodes ipv6 packets
into one packet greatly reducing the risk of amplification attacks.
