Internet Explorer occasionally requests a favicon before doing the
actual redirect to localhost. This commit adds Undertow to properly
handle those unwanted requests.
This is non-intrusive and backwards compatible. With this change it is possible
to `await keycloakAuthorization.ready` to make sure the component has been
properly initialized.
It was incorrectly relying on web application listeners on session
destruction.
While it's used as a Spring Bean (declared in
KeycloakWebSecurityConfigurerAdapter) so it has to use Spring-based
facility.

Sometimes the error message is blank, which results in an empty error line getting logged.
Since the catch always logs "failed to turn code into token" and "status from server: " + failure.getStatus() (on separate lines) this extra blank line is simply noise in the log.
Fix debug message that does not properly handle single quotes
according to java.text.MessageFormat, which in turn causes the
replacement to not be handled.

I use Keycloak Spring Adapter (KSA) to secure existing application. Today I realized that some functions didn't work anymore because of security checking like this:
```
GrantedAuthority adminRole = new MySpecialGrantedAuthority( "superadmin" );
for ( GrantedAuthority role : userRoles ) {
if ( role.equals( adminRole ) ) {
return true;
}
}
```
In this example, when I use KSA authorization fails.
I believe, that more preferable in `KeycloakRole` use this implementation of `equals` method.

Users who want to use PKCE support with the KeycloakInstalled adapter need to set the property
``"enable-pkce": true` in the adapter configuration / `keycloak.json`.
This adds support for the "S256" code_challenge_method to the JS Adapter.
Note that the method "plain" was deliberately left out as is not recommended
to be used in new applications.
Note that this PR includes two libraries:
- [base64-js]{@link https://github.com/beatgammit/base64-js}
- [js-sha256]{@link https://github.com/emn178/js-sha256}
`base64-js` is needed for cross-browser support for decoding the
Uint8ArrayBuffer returned by `crypto.getRandomValues` to a PKCE
compatible base64 string.
`js-sha256` library is required because the `crypto.subtle.digest`
support is not available for all browsers.
The PKCE codeVerifier is stored in the callbackStore of the JS Adapter.
Note: This PR is based on #5255 which got messed up during a rebase.
This is an issue with the Spring Security Keycloak Adapter relating to
the way the Authentication is stored in the SecurityContext, causing a
race condition in application code using that. It does not seem to
affect actual Spring Security operation.
We had a pretty strange race condition in our application. When many
requests were incoming at the same time, occasionally the old
unauthenticated Authentication provided to
KeycloakAuthenticationProvider for performing the actual authentication
would stay the current authentication, as returned by
SecurityContextHolder.getContext().getAuthentication(). That resulted
in authenticated users' JavaScript requests occasionally (~1/50 given a
large request volume) returning a 403 because the 'old' token was still
in the context, causing Spring Security to see them as unauthenticated.
This PR resolves this issue by replacing the whole context, as suggested
by a Spring Security contributor in jzheaux/spring-security-oauth2-resource-server#48. By default,
SecurityContextHolder keeps the actual context object in a ThreadLocal,
which should be safe from race-conditions. The actual Authentication
object, however, is kept in a mere field, hence the reason for this PR.
