Change info log to debug in uTP router connect (#517) 
These uTP logs are common and should be under debug,
else they spam on application level.
Probably accidentally changed in https://github.com/status-im/nim-eth/pull/508

Add event loop to socket (#475) 
- add eventLoop to control all incoming events
- change semantic of write to asynchronously block only when send buffer is full, and not when bytes do not fit into send window
- change handling of receive buffer, to start dropping packets if the reorder buffer and receive buffer are full. Old behaviour was to async block unless there is space which could lead to resource exhaustion attacks

Style fixes according to --styleCheck:usages (#452) 
Currently only setting `--styleCheck:hint` as there are some
dependency fixes required and the compiler seems to trip over the
findnode MessageKind, findnode Message field and the findNode
proc. Also over protocol.Protocol usage.
