We have a function which parses a buffer with a signature at the end, parse_signature, and this function is used for signed tags. However, we'll need to store values for multiple algorithms, and we'll do this by using a header for the non-default algorithm. Adjust the parse_signature interface to store the parsed data in two strbufs and turn the existing function into parse_signed_buffer. The latter is still used in places where we know we always have a signed buffer, such as push certs. Adjust all the callers to deal with this new interface.
