This change introduces 2 new optional methods; `enter()` and `exit()` for js tracers, and makes `step()` optiona. The two new methods are invoked when entering and exiting a call frame (but not invoked for the outermost scope, which has it's own methods). Currently these are the data fields passed to each of them:
enter: type (opcode), from, to, input, gas, value
exit: output, gasUsed, error
The PR also comes with a re-write of the callTracer. As a backup we keep the previous tracing script under the name `callTracerLegacy`. Behaviour of both tracers are equivalent for the most part, although there are some small differences (improvements), where the new tracer is more correct / has more information.
This makes several updates to support the blockupdates plugin.
I had to update several hooks that were using the wrong types, and
provide a way to get event.Feed objects into plugins without importing
event.Feed (which I did by having the plugin loader make them
available).
* cmd/devp2p/internal/ethtest: only use eth66 if eth66 is negotiated
* cmd/devp2p/internal/ethtest: switch on concrete type not pointer
* cmd/devp2p/internal/ethtest: switch on concrete type not pointer
This does some dark magic with reflect to enable plugins to offer
subscriptions without requiring them to use the rpc.Subscriptions
import.
Basically, plugin services can have a channel as a return value,
and the shim will pull items off of that chanel and send them to
the notifier. It makes sure that context.Done() will fire when
the user disconnects, and will shut everything down if the channel
closes.
This PR ensures that wiping all data associated with a node (apart from its nodekey)
will not generate already used sequence number for the ENRs, since all remote nodes
would reject them until they out-number the previously published largest one.
The big complication with this scheme is that every local update to the ENR can
potentially bump the sequence number by one. In order to ensure that local updates
do not outrun the clock, the sequence number is a millisecond-precision timestamp,
and updates are throttled to occur at most once per millisecond.

This change is a rewrite of the freezer code.
When writing ancient chain data to the freezer, the previous version first encoded each
individual item to a temporary buffer, then wrote the buffer. For small item sizes (for
example, in the block hash freezer table), this strategy causes a lot of system calls for
writing tiny chunks of data. It also allocated a lot of temporary []byte buffers.
In the new version, we instead encode multiple items into a re-useable batch buffer, which
is then written to the file all at once. This avoids performing a system call for every
inserted item.
To make the internal batching work, the ancient database API had to be changed. While
integrating this new API in BlockChain.InsertReceiptChain, additional optimizations were
also added there.

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.
