io.Reader may return n > 0 and io.EOF at the end of the input stream.
readFull did not handle this correctly, looking only at the error. This fixes
it to check for n == len(buf) as well.

* core/state: copy the snap when copying the state

* core/state: deep-copy snap stuff during state Copy

This PR optimizes the broadcast loop. Instead of iterating twice through a given set of transactions to weed out which peers have and which do not have a tx, to send/announce transactions, we do it only once.

eth: fix snap sync cancellation

This updates the eth protocol test suite to use the message type
definitions of the 'production' protocol implementation in eth/protocols/eth.

cmd/utils, eth/ethconfig: unindex txs older than ~1 year

There was a dormant error with structured inputs that failed unpacking.
This commit fixes the error by switching casting to the better abi.ConvertType function.
It also adds a test for calling a view function that returns a struct

adds a flag --log.json which if enabled makes the client format logs with JSON.

cmd/utils: enable snapshots by default

fixes an regression which caused build failure on certain platforms

Prevents a situation where we (not running snap) connects with a peer running snap, and get stalled waiting for snap registration to succeed (which will never happen), which cause a waitgroup wait to halt shutdown

This moves the eth config definition into a separate package, eth/ethconfig. 
Packages eth and les can now import this common package instead of
importing eth from les, reducing dependencies.

This pr adds consensys' gurvy bn256 variant into the code for differential fuzzing.

fixes an issue where local transactions that were included in the chain before a SetHead were rejected if resubmitted, since the txpool had not reset the state to the current (older) state.

The PR makes use of the stacktrie, which is is more lenient on resource consumption, than the regular trie, in cases where we only need it for DeriveSha
