514d5db038 Update Network Protocol
- now last digit version is compatible 0.6.0 will connect to 0.6.1
 - the TCP DATA Frames no longer contain START field, as it's not needed
 - the TCP OPENSTREAM Frames will now contain the BANDWIDTH field
 - MID is not Protocol internal

Update network
 - update API with Bandwidth

Update veloren
 - introduce better runtime and `async` things that are IO bound.
 - Remove `uvth` and instead use `tokio::runtime::Runtime::spawn_blocking`
 - remove futures_execute from client and server use tokio::runtime::Runtime instead
 - give threads a Name

03af9937cf Stabelize Network again:
- completly switch to Bytes, even in api. speed up TCP by fak 2
 - improve benchmarks
 - speed up mpsc metrics
 - gracefully handle shutdown by interpreting Ok(0) as tokio::tcpstream closed now.
 - fix hotloop in participants by adding `Some(n)` to fix endless handing.
 - fix closing bug by closing streams after `recv_mgr` is shutdown even if now shutdown is triggered locally.
 - fix prometheus
 - no longer throw when a `Stream` is dropped while participant still receives a msg for it.
 - fix the bandwith handling, TCP network send speed is up to 1.5GiB/s while recv is 150MiB/s
 - add documentation
 - tmp require rt-multi-threaded in client for tokio, to not fail cargo check

this is prob stable, i tested over 1 hour.
after that some optimisations in priomgr.
and impl. propper bandwith.
Speed is up to 2GB/s write and 150MB/s recv on a single core

sync add documentation

ea8ab1ce7a Great improvements to the codebase:
- better logging in network
 - we now notify the send of what happened in recv in participant.
 - works with veloren master servers
 - works in singleplayer, using a actual mid.
 - add `mpsc` in whole stack incl tests
 - speed up internal read/write with `Bytes` crate
 - use `prometheus-hyper` for metrics
 - use a metrics cache

9884019963 COMPLETE REDESIGN of network crate
- Implementing a async non-io protocol crate
    a) no tokio / no channels
    b) I/O is based on abstraction Sink/Drain
    c) different Protocols can have a different Drain Type
       This allow MPSC to send its content without splitting up messages at all!
       It allows UDP to have internal extra frames to care for security
       It allows better abstraction for tests
       Allows benchmarks on the mpsc variant
       Custom Handshakes to allow sth like Quic protocol easily
 - reduce the participant managers to 4: channel creations, send, recv and shutdown.
   keeping the `mut data` in one manager removes the need for all RwLocks.
   reducing complexity and parallel access problems
 - more strategic participant shutdown. first send. then wait for remote side to notice recv stop, then remote side will stop send, then local side can stop recv.
 - metrics are internally abstracted to fit protocol and network layer
 - in this commit network/protocol tests work and network tests work someway, veloren compiles but does not work
 - handshake compatible to async_std
