Refactoring TALER_AgeCommitment
Instead of a single struct TALER_AgeCommitment, we now use
1. TALER_AgeCommitment for the age mask and list public keys for age
restriciton.
2. TALER_AgeProof for list of private keys for age restriction
3. TALER_AgeCommitmentProof for the aggregation of the former two.
Also, we introduce TALER_AgeAttestation as the EDDSA signature to attest
a particular age group, along with the function prototypes
TALER_age_commitment_attest and TALER_age_commitment_verify.
