* disconnect peers that send non-hello messages during initial hello
step
* fix devp2p protocol version - 4 because we don't implement snappy
(yet) - this is cosmetic since this particular version field is not
actually being used
* fix ack message length checking
* move RLPx transport code to separate module, annotate with asyncraises
* increase max RLPx message size to 16mb, per EIP-706
* make sure both accept/connect timeout after 10s
* aim to log every connection attempt once at debug level
* make capability-id/context-id check more accurate
* disallow random messages before hello
* Refactor p2pProtocol internals
* Attempt to fix rlp crash with Nim v2 (#658)
* Attempt to fix rlp crash with Nim v2
* Fix test_ecies for nim v2
* Reduce compiler warnings
* Resolve ambiquity in testutils
* Disable nim devel continue-on-error
Nim devel brach(1.7.1) introduce gc=orc as default mode.
Because the p2p protocol using unsafe pointer operations
for it's ProtocolInfo and using global variables scattered
around, the orc mistakenly(or maybe correctly) crash the protocol.
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.
Lib2P2 handles RPC requests and responses with separate streams
while DEV2P2 is relying on tagged messages transmitted over a
single stream. To cover both models through the same application
code, we introduce a new `response` variable in the request handlers.
The user is supposed to issue a call to `response.send` in order to
reply to the request. Please note that the `response.send` signature
is strongly typed and depends on the current message.
