* Miscellaneous updates TBC
* Disentangled pivot2 module from snap
why:
Wrote as template on top of sync so it can be shared by fast and snap
sync.
* Renamed and relocated pivot sources
* Integrated `best_pivot` module into full and snap sync
why:
Full sync used an older version of `best_pivot`
* isolating download module from full sync
why;
might be shared with snap sync at a later stage
Also requires us to split header data propagation from block body
and receipts propagation as the now fixed bug would allow for more
data to be gossiped even when data does not get validated (which
requires the headers).
* Added inspect module
why:
Find dangling references for trie healing support.
details:
+ This patch set provides only the inspect module and some unit tests.
+ There are also extensive unit tests which need bulk data from the
`nimbus-eth1-blob` module.
* Alternative pivot finder
why:
Attempt to be faster on start up. Also tying to decouple pivot finder
somehow by providing different mechanisms (this one runs in `single`
mode.)
* Use inspect module for healing
details:
+ After some progress with account and storage data, the inspect facility
is used to find dangling links in the database to be filled nose-wise.
+ This is a crude attempt to cobble together functional elements. The
set up needs to be honed.
* fix scheduler to avoid starting dead peers
why:
Some peers drop out while in `sleepAsync()`. So extra `if` clauses
make sure that this event is detected early.
* Bug fixes causing crashes
details:
+ prettify.toPC():
int/intToStr() numeric range over/underflow
+ hexary_inspect.hexaryInspectPath():
take care of half initialised step with branch but missing index into
branch array
* improve handling of dropped peers in alternaive pivot finder
why:
Strange things may happen while querying data from the network.
Additional checks make sure that the state of other peers is updated
immediately.
* Update trace messages
* reorganise snap fetch & store schedule
In preparation of our migration to the new Nimble-based setup
and [nim-workspace][1], we switch to a new model where the vendor
packages are no longer imported through a locally generated Nimble
dir, but rather through an auto-generated `nimbus-build-system.paths`
file that features regular `--path:` statements.
This file will be imported only within the nimbus-build-system
environment in order to avoid any unwanted interference in working
copies based on the new Nimble setup.

* Fix bug in inCurrentEpoch and improve accumulator related tests
- Fix negative wraparound / underflow in inCurrentEpoch
- Add tests in accumulator tests to verify the above
- Add header offer tests with accumulator that does and doesn't
contain historical epochs
- Additional clean-up of history tests
- enable canonicalVerify in the tests
