3cb9612faa test: add test for Taproot activation (Andrew Poelstra)
5291c0d9d9 chainparams: add undocumented regtest/testnet only -con_taproot_signal_start option (Andrew Poelstra)
cc6b933478 add missing taproot activation params for Liquid v1 (Andrew Poelstra)
bec6bcf31b versionbits: allow specific deployments to override the signalling/threshold values (Andrew Poelstra)
Pull request description:
Sets Taproot to start signalling around noon (California time) on Nov 1, 2021, assuming 95% of blocks are produced between now and then.
Will activate after one week of 100% signalling. If we can pull this off on the first or second try, we will beat Bitcoin which currently looks like it will activate on Nov 16.
**Edit:** actually, even without Speedy Trial, there is one full period (week) where Taproot will be "locked in" but not "active". So it will activate on Nov 15 at the earliest.

Includes a memory leak in the checkqueue unit test (but not in
the actual code). WE really need to switch our checkqueue to use
std::unique_pointer rather than bare pointers. But this would be
invasive enough that I want to do it in a followup PR.
Also pretty-much disable the validation_flush_cache unit test.
This is a stupid and irritating test which tries to unit-test
exact memory usage of std containers. It already has at least
one "remove wrong assumptions" update upstream and after many
tries I was unable to change all the magic numbers in a way
that'd consistently pass CI for Elements.
Also adds a couple ubsan suppressions about perfectly-legitimate
conversions of integer types.
This commit adds signet support, which is a little bit silly/redundant for us :)
Was a surprisingly easy merge to handle, and hopefully in future Core is more
mindful of signed blocks when they are changing code architecture.
I had to change a couple lines of src/signet.cpp to add blank assets to the
CTxOuts and to find transaction input scriptWitnesses. No need to add any
other tx witness data (and the CAsset()s that I did add to make things compile
won't be used..) because signet will always have g_con_elementsmode off.
FIXME: we disable standardness checks for the non-PAK node in the PAK tests.
This is because of a bug in Elements which causes non-PAK nodes to reject
pegouts for standardness reasons. Need to fix it after the rebase.
