    Parameters:
    
    key - local public key
    
    copy - copy of the public key (e.g. from a key server)
    
    joinTrustPackets - if true, trust packets from the copy are copied over into the resulting key
    
    allowSubkeySigsOnNonSubkey - if true, subkey signatures on the copy will be present in the merged key, even if key was not a subkey before.
