bitbake: prserv: add extra requests

Useful for connecting a PR server to an upstream one

- "test-package" checks whether the specified package
  version and arch is known in the database.

- "test-pr" checks a specified output hash is found in the database.
  Otherwise it returns 'None' instead of a new value.

- "max-package-pr" returns the highest PR number for
  (version, arch) entries in the database, and None if not found

Add new DB functions supporting the above, plus test_value()
which tells whether a given value is available for the specified
package and architecture.
