p2p: panic on transport error (#2968) 
* p2p: panic on transport error

Addresses #2823. Currently, the acceptRoutine exits if the transport returns
an error trying to accept a new connection. Once this happens, the node
can't accept any new connections. So here, we panic instead. While we
could potentially be more intelligent by rerunning the acceptRoutine, the
error may indicate something more fundamental (eg. file desriptor limit)
that requires a restart anyways. We can leave it to process managers to
handle that restart, and notify operators about the panic.

bdd01310a0 p2p: Integrate new Transport 
We are swapping the exisiting listener implementation with the newly
introduced Transport and its default implementation MultiplexTransport,
removing a large chunk of old connection setup and handling scattered
over the Peer and Switch code. The Switch requires a Transport now and
handles externally passed Peer filters.

6fad8eaf5a [p2p/pex] connect to more than 10 peers (#2169) 
* [p2p/pex] connect to more than 10 peers

also, remove DefaultMinNumOutboundPeers because a) I am not sure it's
needed b) it's super confusing

look closely

```
maxPeers := sw.config.MaxNumPeers - DefaultMinNumOutboundPeers
if maxPeers <= sw.peers.Size() {
  sw.Logger.Info("Ignoring inbound connection: already have enough peers", "address", inConn.RemoteAddr().String(), "numPeers", sw.peers.Size(), "max", maxPeers)
```

we print maxPeers = config.MaxPeers - DefaultMinNumOutboundPeers. So we
may not have enough peers even though we say we have enough.

Refs #2130

* update spec

* replace MaxNumPeers with MaxNumInboundPeers/MaxNumOutboundPeers

Refs #2130

* update changelog

* make max rpc conns formula visible to users

* update spec

* docs: note max outbound peers excludes persistent

revert back to Jae's original payload size limit 
except now we calculate the max size using the maxPacketMsgSize()
function, which frees developers from having to know amino encoding
details.

plus, 10 additional bytes are added to leave the room for amino upgrades
(both making it more efficient / less efficient)

Fix race when mutating MConnConfig 
Instead of mutating the passed in MConnConfig part of P2PConfig we just
use the default and override the values, the same as before as it was
always the default version. This is yet another good reason to not embed
information and access to config structs in our components and will go
away with the ongoing refactoring in #1325.

Collapse PeerConfig into P2PConfig 
As both configs are concerned with the p2p packaage and PeerConfig is
only used inside of the package there is no good reason to keep the
couple of fields separate, therefore it is collapsed into the more
general P2PConifg. This is a stepping stone towards a setup where the
components inside of p2p do not have any knowledge about the config.

only log errors, dial correct addresses

do not even try to dial ourselves 
also, remove address from the book (plus mark it as our address)
and return an error if we fail to parse peers list
