Pull request description:
It's been 1.5 years since our secp256k1 subtree was updated, while the upstream project has undergone a number of incremental improvements (performance, tests, build system fixes), plus gained the groundwork for batch verification.
As we're early in the 0.19 window, this seems like a good time to get these merged.

Note: This is added to our existing automake targets rather than as a
libtool-style lib. The switch to libtool-style targets can come later if it
proves to not add any complications.
