Currently, setDefaults overwrites the transaction input value if only input is provided. This causes personal_sendTransaction to estimate the gas based on a transaction with empty data. eth_estimateGas never calls setDefaults so it was unaffected by this.
Currently rpc.BlockNumber is marshalled to JSON as a numeric value, which is
wrong because BlockNumber.UnmarshalJSON() wants it to either be hex-encoded
or string "earliest"/"latest"/"pending". As a result, the call chain
rpc.BlockNumberOrHashWithNumber(123) -> json.Marshal() -> json.Unmarshal()
fails with error "cannot unmarshal object into Go value of type string".
As per benchmark results below, these changes speed up encoding/decoding of
consensus objects a bit.

* rlp: pass length to byteArrayBytes
This makes it possible to inline byteArrayBytes. For arrays, the length is known
at encoder construction time, so the call to v.Len() can be avoided.
* rlp: avoid IsNil for pointer encoding
It's actually cheaper to use Elem first, because it performs less checks
on the value. If the pointer was nil, the result of Elem is 'invalid'.
* rlp: minor optimizations for slice/array encoding
For empty slices/arrays, we can avoid storing a list header entry in the
encoder buffer. Also avoid doing the tail check at encoding time because
it is already known at encoder construction time.
This PR adds functionality to the evm t8n to calculate ethash difficulty. If the caller does not provide a currentDifficulty, but instead provides the parentTimestamp (well, semi-optional, will default to 0 if not given), and parentDifficulty, we can calculate it for him.
The caller can also provide a parentUncleHash. In most, but not all cases, the parent uncle hash also affects the formula. If no such hash is provided (or, if the empty all-zero hash is provided), it's assumed that there were no uncles.
The new linter version is built with go 1.17 and thus includes the go vet
check for mismatched +build and go:build lines.
Fortunately, no new warnings are reported with this update.
In p2p/dial.go, conn.flags was accessed without using sync/atomic.
This race is fixed by removing the access.
In p2p/enode/iter_test.go, a similar race is resolved by writing the field atomically.

This PR adds flag to enable InfluxDB v2 (--metrics.influxdbv2), flags for v2-specific features (--metrics.influxdb.token, --metrics.influxdb.bucket), also carries over addition of support for specifying organization (--metrics.influxdb.organization), but still retains backwards compatibility with InfluxDB v1.
