PK: document context validity requirements

Document when a context must be initialized or not, when it must be
set up or not, and whether it needs a private key or a public key will
do.

The implementation is sometimes more liberal than the documentation,
accepting a non-set-up context as a context that can't perform the
requested information. This preserves backward compatibility.
