Messy merge conflicts because this PR backported some ad-hoc stuff from upstream while keeping a few things that upstream deleted. Hopefully reviewing is easier than doing this in the first place, since ultimately all I did was delete code from one side or another of the conflicts. (Ok, I also changed some boost optional stuff to std::optional, and had to patch up a test file for test framework changes.) When reviewing the detailed crypto, bear in mind that taptweaks, like all hashes are the kind of crypto that cannot be subtly wrong -- it will either fail very hard or be correct. And we have independent implementations in C++ and Python that cross-check each other, si it's unlikely to be the former.
