credstore: Pass additional information to Identity Credential HAL.

Without this extra information passed upfront it's not practical to
implement a HAL which incrementally builds up cryptographically
authenticated data.

This information is conveyed by using two new methods on version 2 of
the Identity Credential HAL. If these methods are not implemented (if
a version 1 HAL is running) the invocation fails and we handle this
gracefully by just ignoring the error.
