Now that we have full support in Git for the authtype capability, let's add support to the cache credential helper. When parsing data, we always set the initial capabilities because we're the helper, and we need both the initial and helper capabilities to be set in order to have the helper capabilities take effect. When emitting data, always emit the supported capability and make sure we emit items only if we have them and they're supported by the caller. Since we may no longer have a username or password, be sure to emit those conditionally as well so we don't segfault on a NULL pointer. Similarly, when comparing credentials, consider both the password and credential fields when we're matching passwords. Adjust the partial credential detection code so that we can store credentials missing a username or password as long as they have an authtype and credential.
