test: add reset_chainstate parameter for snapshot unittests

This CreateAndActivateUTXOSnapshot parameter is necessary once we
perform snapshot completion within ABC, since the existing UpdateTip
test will fail because the IBD chain that has generated the snapshot
will exceed the base of the snapshot.

Being able to test snapshots being loaded into a mostly-uninitialized
datadir allows for more realistic unittest scenarios.

https://github.com/bitcoin/bitcoin/pull/25667/commits/3c361391b8f5971eb3c7b620aa7ad9b437cc515e

Backport note: this process of resetting the chainstate without also resetting the block index would cause CheckBlockIndex to fail on assert(setBlockIndexCandidates.count(pindex))); after D4717 made CheckBlockIndex run on intermediate steps in ActiveBestChain. I disabled CheckBlockIndex until after the snapshot chain is activated.

This is a partial backport of core#25667
Depends on D14652

PiRK planned changes to this revision.Oct 19 2023, 15:35

i got the order of the arguments wrong because I had to resort the commits. reset_chainstate must be before in_memory_chainstate at the end of the backport

Not actually requesting changes, but this question has to be answered before this can move forward

src/test/util/chainstate.h
73	Is that thread safe ?

src/test/util/chainstate.h
73	At the moment there is no thread-safety issue here. This global is set once in init.cpp or in the test fixture constructor, and only read in `CheckBlockIndex`which is always accessed in the same thread.
