core/state/snapshot: add generation logs to storage too

cmd/faucet: update the embedded website asset

The tests sometimes failed with certain go versions because
the behavior of http.Server.Shutdown changed over time. A bug
that was fixed in Go 1.15 could cause active connections on unrelated
servers to close unexpectedly. This is fixed by avoiding use of the
same port number in all tests.

It seems that the 2 second timeout is not enough for Travis CI:

   --- FAIL: TestTestMode (2.00s)
       ethash_test.go:53: sealing result timeout

This solves an issue in graphql tests:

    graphql_test.go:38: could not create new node: datadir already used by another process

USB enumeration still occured. Make sure it will only occur if --usb is set.
This also deprecates the 'NoUSB' config file option in favor of a new option 'USB'.

* deps: use improved bloom filter implementation

* eth/protocols, trie: revert change on syncbloom method signature

Resolves https://github.com/etclabscore/core-geth/issues/273



jsre.JSRE already handles establishing preload
file paths relative to the 'assets' path (aka docroot),
where it joins the assets dir and the file path if relative,
or uses the file path only if absolute.

The duplication of this logic by MakeConsolePreloads
caused preloaded files to have paths which contained
duplicate references to the assets dir path.

This changes the chainID RPC method to return an error when EIP-155 is not yet
active at the current block height. It used to simply return zero in this case, but
that's confusing.

This reverts commit 108033ebc6985de83791d375b6e6647a77d28d5a.

This commit extends the ethclient test suite and increases code coverage of the ethclient
package from ~15% to >55%. These tests act as early smoke tests to signal issues in the
RPC-interface. E.g. if a functionality like eth_chainId or eth_call breaks, the test
will break.

Solidity 0.8.0 changes the way that output is marshalled. This patch allows to parse both
the legacy format used previously and the new format.

This changes the JSON encoding of blocks returned by the API
to have decimal instead of hexadecimal numbers. The spec wants
it this way.

This PR removes a logic in the miner, which was originally intended to help temporary testnets based on ethash from "running off into the future". If the difficulty was low, and a few computers started mining several blocks per second, the ethash rules (which demand 1s delay between blocks) would push the blocktimes further and further away.
The solution was to make the miner sleep while this happened.

Nowadays, this problem is solved instead by PoA chains, and it's recommended to let testnets and devnets be based on clique instead. The existing logic is problematic, since it can cause stalls within the miner making it difficult for remote workers to submit work if the channel is blocked on a sleep.
