CLI rewrite

The command line tools' origin as a collection of examples and test
programs glued together led to some unfortunate problems; lots of
hardcoded values, missing parameters, and obsolete crypto.

Adds a small library for writing command line programs of the sort
needed here (cli.h), which cuts the length of many of the commands in
half and makes commands more pleasant to write and extend.

Generalizes a lot of the commands also, eg previously only
signing/verification with DSA/SHA-1 was included!

Removes the fuzzer entry point since that's fairly useless outside of
an instrumented build.

Removes the in-library API for benchmarking.
