* @mfmarche on 24 Feb: when code_verifier is set, don't check client_secret
In PKCE flow, no client_secret is used, so the check for a valid client_secret
would always fail.

* PKCE: Check clientSecret when available
In authorization_code flow with PKCE, allow empty client_secret on /auth and /token endpoints. But check the client_secret when it is given.
Signed-off-by: Bernd Eckstein <Bernd.Eckstein@faro.com>
* Enable PKCE with public: true
dex configuration public on staticClients now enables the following behavior in PKCE:
- Public: false, PKCE will always check client_secret. This means PKCE in it's natural form is disabled.
- Public: true, PKCE is enabled. It will only check client_secret if the client has sent one. But it allows the code flow if the client didn't sent one.

Having ID and Secret in clear inside configuration files for static
clients is not ideal. This commit allows setting these from environment
variables.

The "at_hash" claim, which provides hash verification for the
"access_token," is a required claim for implicit and hybrid flow
requests. Previously we did not include it (against spec). This
PR implements the "at_hash" logic and adds the claim to all
responses.
As a cleanup, it also moves some JOSE signing logic out of the
storage package and into the server package.
For details see:
https://openid.net/specs/openid-connect-core-1_0.html#ImplicitIDToken
Dex's Postgres client currently uses the `timestamp` datatype for
storing times. This lops of timezones with no conversion, causing
times to lose locality information.
We could convert all times to UTC before storing them, but this is
a backward incompatible change for upgrades, since the new version
of dex would still be reading times from the database with no
locality.
Because of this intrinsic issue that current Postgres users don't
save any timezone data, we chose to treat any existing installation
as corrupted and change the datatype used for times to `timestamptz`.
This is a breaking change, but it seems hard to offer an
alternative that's both correct and backward compatible.
Additionally, an internal flag has been added to SQL flavors,
`supportsTimezones`. This allows us to handle SQLite3, which doesn't
support timezones, while still storing timezones in other flavors.
Flavors that don't support timezones are explicitly converted to
UTC.
ghodss/yaml converts from YAML to JSON before attempting to unmarshal.
This allows us to:
* Get the correct behavor when decoding base64'd []byte slices.
* Use *json.RawMessage.
* Not have to support extravagant YAML features.
* Let our structs use `json:` tags
Currently, whether or not a user has authenticated themselves through
a connector is indicated by a pointer being nil or non-nil. Instead
add an explicit flag that marks this.
