Seems there are two occasions possible where we try to ping the
own local node which causes an assert
- One via the bounding
- One via a received ping, which is strange in the first place but
notice in a stack trace
* Move NetworkId type to common eth_types
NetworkId is after all a common type and this way it avoid an
application that requires it to also import all devp2p related
network types.
RLP related calls are moved to eth_types_rlp, this means that p2p
protocols that send NetworkId over the wire need to import this
too. Or just common in general.
* Remove # in front of multiline comment end bracket
These seem to be interpreted wrongly by the GitHub code browser.
This is specifically useful for when the failure is caused by an
"Operation not permitted", as then we can see for which specific
port(s) a firewall might be blocking outgoing traffic.
* tighter nimcrypto imports
* install openssl on macos for Nim devel
* add getTotalDifficulty base method to AbtractChainDB

`eth_types` is being imported from many projects and ends up causing
long build times due to its extensive import lists - this PR starts
cleaning some of that up by moving the chain DB and RLP to their own
modules.
this PR also moves `keccakHash` to its own module and uses it in many
places.
* Fix stability issues
why:
Handling malformed messages typically raises `RangeError` exceptions
when de-serialising RLP, or decoding message data. This is an
(incomplete) attempt to weed out some out it driven by real live
tests.
remark:
Employing the new `snap` protocol there might be different views on what
the messages really contain (currently specs are more a hint.)
* Update RLP exception handling
* Undo effect-less patch
why:
problem occurred somewhere above the try/catch handler
* Using `checkedEnumAssign()` for RLP enum
* Provide dedicated `DisconnectionReason` enum type RLP reader
why:
Without this reader, the program communicating via RLPX will crash when
receiving out of bound reason codes disconnect message.
Out of bound value assignments to an enum causes a `RangeError`defect
and consequently the program to terminate. This `RangeError` is avoided
here and a `MalformedRlpError` catchable error raised.
* Using default exception type in bespoke `read(DisconnectionReason)`
why:
This should not differ from the default enum parser. The particular
message is different and more targeted, here.
Note: The default RLP parser was not used because `
`array[1,DisconnectionReason]` is currently not properly handled and
should give a siliar error message as a `DisconnectionReason` error.
* De-clutter, custom read() was not needed

* Handle the decodeAuthMessage error case separatly and log to trace
Garbage data on the TCP port (e.g. from port scanners) would
cause lots of error log messages, so log this to trace and get rid
of a (little) bit of exception usage in the process.
* Remove usage of result var in rlpxAccept and rlpxConnect
* Discv4: Add ENRRequest & ENRResponse msgs to avoid fails on these
Fix#499
These messages are not implemented yet however, but just ignored.
