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.

* cmd/geth: added --mainnet flag

* cmd/utils: set default genesis if --mainnet is specified

* cmd/utils: addressed comments

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.

The legacy dot-org URL was displaying a message about the repository
having migrated to the dot-com service, which now covers open-source
projects as well.

* common,crypto: move fuzzers out of core

* fuzzers: move vm fuzzer out from core

* fuzzing: rework cover package logic

* fuzzers: lint

During the snap and eth refactor, the net_version rpc call was falsely deprecated.
This restores the net_version RPC handler as most eth2 nodes and other software
depend on it.

* eth/download/statesync : state hash sum optimized

* go fmt with blank in imports

* keccak read arg fix

* les: allow tx unindexing in les/4 light server mode

* les: minor fixes

* les: more small fixes

* les: add meaningful constants for recentTxIndex handshake field

This commit splits the eth package, separating the handling of eth and snap protocols. It also includes the capability to run snap sync (https://github.com/ethereum/devp2p/blob/master/caps/snap.md) , but does not enable it by default.

Fixes the template used when generating code, which in some scenarios would lead to panic instead of returning an error.

This PR implements unclean shutdown marker. Every time geth boots, it adds a timestamp to a list of timestamps in the database. This list is capped at 10. At a clean shutdown, the timestamp is removed again. 
Thus, when geth exits unclean, the marker remains, and at boot up we show the most recent unclean shutdowns to the user, which makes it easier to diagnose root-causes to certain problems.

This PR adds re-written difficulty calculators, which are based on uint256. It also adds a fuzzer + oss-fuzz integration for the new fuzzer. It does differential fuzzing between the new and old calculators.

Note: this PR does not actually enable the new calculators.

This PR adds support for using Twitter API to query the tweet and author details. There are two reasons behind this change:

- Twitter will be deprecating the legacy website on 15th December. The current method is expected to stop working then.
- More importantly, the current system uses Twitter handle for spam protection but the Twitter handle can be changed via automated calls. This allows bots to use the same tweet to withdraw funds infinite times as long as they keep changing their handle between every request. The Rinkeby as well as the Goerli faucet are being actively drained via this method. This PR changes the spam protection to be based on Twitter IDs instead of usernames. A user can not change their Twitter ID.
