which gives us everything we want.

bitcoin: hand in a secp256k1_context to all routines.
...
We don't want to re-create them internally, ever.
The test-cli tools are patched to generate them all the time, but
they're not performance critical.

bitcoin: signature fixes.
...
The libsecp change broke signature checking. Disable it for now,
with a big FIXME. The next version should have a method for S value
checking, and also compact serialization.

signature: fix invalid S check.
...
The even-S check was based on https://github.com/sipa/bitcoin/commit/a81cd9680
which was replaced by a low-S check in commit e0e14e43d9586409e42919f6cb955540134cda2a
Abstract out and fix the check.
