This change introduces a breaking change to miner.etherbase is configured.
Previously, users did not need to explicitly set the etherbase address via flag, since 'first' local account was used as etherbase automatically. This change removes the "default first account" feature.
In Proof-of-stake world, the fee recipient address is provided by CL, and not configured in Geth any more - meaning that miner.etherbase is mostly for legacy networks(pow, clique networks etc).
This PR introduces a node scheme abstraction. The interface is only implemented by `hashScheme` at the moment, but will be extended by `pathScheme` very soon.
Apart from that, a few changes are also included which is worth mentioning:
- port the changes in the stacktrie, tracking the path prefix of nodes during commit
- use ethdb.Database for constructing trie.Database. This is not necessary right now, but it is required for path-based used to open reverse diff freezer

The PR makes use of the stacktrie, which is is more lenient on resource consumption, than the regular trie, in cases where we only need it for DeriveSha
* miner: exit loop when downloader Done or Failed
Following the logic of the comment at the method,
this fixes a regression introduced at 7cf56d6f06
, which would allow external parties to DoS with
blocks, preventing mining progress.

* miner: fix waitForMiningState precision
This helper function would return an affirmation
on the first positive match on a desired bool.
This was imprecise; it return false positives
by not waiting initially for an 'updated' value.
This fix causes TestMiner_2 to fail, which is
expected.

* miner: add test describing expectations for downloader/mining events
We expect that once the downloader emits a DoneEvent,
signaling a successful sync, that subsequent StartEvents
are not longer permitted to stop the miner.
This prevents a security vulnerability where forced syncs via
fake high blocks would stall mining operation.

* miner: use 'canStop' state to fix downloader event handling
- Break downloader event handling into event
separating Done and Failed events. We need to
treat these cases differently since a DoneEvent
should prevent the miner from being stopped on
subsequent downloader Start events.
- Use canStop state to handle the one-off
case when a downloader first succeeds.

* miner: refactor miner update logic w/r/t downloader events
This makes mining pause/start logic regarding downloader

when downloader events are no longer actionable.

* miner: refactor update loop to remove race condition
The go routine handling the downloader events handling
vars in parallel with the parent routine, causing a
race condition.
This change, though ugly, remove the condition while
still allowing the downloader event subscription to be
closed when the miner has no further use for it (ie DoneEvent).

This PR changes several different things:
- Adds test cases for the miner loop
- Stops the worker if it wasn't already stopped in worker.Close()
- Uses channels instead of atomics in the miner.update() loop
