Kevin Roast 7f24c8c4e7 Merged V3.2E to HEAD
17246: ETHREEOH-3208: User profiles for users authenticated by immutable subsystems are now read only
         - Introduced MutableAuthenticationService interface, only implemented by Alfresco native authentication service
         - Split out those methods from AuthenticationService that mutate the user store and added isAuthenticationMutable()
         - Now both Alfresco Explorer and Share user profile / password edit link rendering is conditional on isAuthenticationMutable
         - Works with authentication chain containing mixture of internally and externally authenticated users
   17247: Fix failing unit tests
         - rm-public-services-security-context.xml needed to be brought in line with public-services-security-context.xml (and will forever more!)
   17248: ETHREEOH-1593: alfUser cookie value should be base 64 encoded to allow for non-ASCII characters
   17253: *RECORD ONLY* ETHREEOH-2885: web.xml must conform to the schema to work on JBoss

/**
* This class implements a simple chaining authentication service. It chains together other authentication services so
* that authentication can happen against more than one authentication service. The authentication services it uses are
* stored as a list. Each authentication service must belong to the same domain. This is checked at configuration time.
* Authentication will try each authentication service in order. If any allow authentication given the user name and
* password then the user will be accepted. Additions, deletions and password changes are made to one special
* authentication service. This service will be tried first for authentication. Users can not be created if they exist
* in another authentication service. To avoid transactional issues in chaining, the services registered with this
* service must not have transactional wrappers. If not, errors will mark the transaction for roll back and we can not
* chain down the list of authentication services.
