All encoding/decoding operations read the type cache to find the
writer/decoder function responsible for a type. When analyzing CPU
profiles of geth during sync, I found that the use of sync.RWMutex in
cache lookups appears in the profiles. It seems we are running into
CPU cache contention problems when package rlp is heavily used
on all CPU cores during sync.

This change makes it use atomic.Value + a writer lock instead of
sync.RWMutex. In the common case where the typeinfo entry is present in
the cache, we simply fetch the map and lookup the type.

This PR updates the miner stress tests and moves them to standalone
packages, so that they can be run directly.

This change extracts the peer QoS tracking logic from eth/downloader, moving
it into the new package p2p/msgrate. The job of msgrate.Tracker is determining
suitable timeout values and request sizes per peer.

The snap sync scheduler now uses msgrate.Tracker instead of the hard-coded 15s
timeout. This should make the sync work better on network links with high latency.

This commit makes various cleanup changes to rlp.Stream.

* rlp: shrink Stream struct

This removes a lot of unused padding space in Stream by reordering the
fields. The size of Stream changes from 120 bytes to 88 bytes. Stream
instances are internally cached and reused using sync.Pool, so this does
not improve performance.

* rlp: simplify list stack

The list stack kept track of the size of the current list context as
well as the current offset into it. The size had to be stored in the
stack in order to subtract it from the remaining bytes of any enclosing
list in ListEnd. It seems that this can be implemented in a simpler
way: just subtract the size from the enclosing list context in List instead.

This changes the definitions of Ping and Pong, adding an optional field
for the sequence number. This field was previously encoded/decoded using
the "tail" struct tag, but using "optional" is much nicer.

* forkid: added failing test

* forkid: fixed off-by-one bug

This PR fixes two errors that regressed when EIP-1559 was merged.

This is the initial implementation of EIP-1559 in packages core/types and core.
Mining, RPC, etc. will be added in subsequent commits.

consensus/ethash: implement EIP-3554 (bomb delay)

* Ensure state could be created in ToBlock

* Fix rebase errors

* use a panic instead

eth/tracers: do the JSON serialization via .js to capture C faults

This adds a cmd line parameter `--gpo.ignoreprice`, to make the gas price oracle ignore transactions below the given threshold.

* core/types: remove support for legacy receipt storage encoding

* core/types: remove support for legacy log storage encoding

Getting the raw value is not necessary to decode this type, and
decoding it directly from the stream is faster.

'geth monitor' subcommand is no longer supported.

This adds support for a new struct tag "optional". Using this tag, structs used
for RLP encoding/decoding can be extended in a backwards-compatible way,
by adding new fields at the end.
