Rather than hard-coding assumptions about the line endings, use a
PrintWriter to produce the multi-line expected output

Fixes #1446

Fixes gh-947

See gh-947

Add a sample application that can be deployed to WildFly to demonstrate
how JTA can be used when running in a application server.

See gh-947

Update auto-configuration for JMS and JTA to support a ConnectionFactory
and TransactionManager exposed via JNDI.

JTA configuration now attempts a simple JtaTransactionManager before
attempting Bitronix or Atomikos configuration.

The JMS auto-configuration also now attempts to find a ConnectionFactory
from JNDI before falling back to the previous strategies. If JNDI is
present a JndiDestinationResolver is also configured instead of the
default DestinationResolver.

See gh-947

Add samples and integration tests for Atomikos and Bitronix JTA.

See gh-947

Add starters for Atomikos and Bitronix JTA libraries.

See gh-947

Update JMS auto-configuration for ActiveMQ and HornetQ to support XA
transactions.

See gh-947

Update DataSource and JPA auto-configuration to consider XA datasources.

See gh-947

Add auto-configuration for the Atomikos and Bitronix JTA libraries.

See gh-947

Add SpringJtaPlatform Hibernate AbstractJtaPlatform implementation. Also
relocated SpringNamingStrategy to the `hibernate` sub-package.

See gh-947

Add support classes for the Bitronix JTA library, including:

- A Spring friendly ConnectionFactoryBean and DataSourceBean with
  support for setting a direct XA source.
- A PostProcessor to apply shutdown ordering automatically.

See gh-947

Add support classes for the Atomikos JTA library, including:

- A Spring friendly ConnectionFactoryBean and DataSourceBean.
- A PostProcessor to apply "depends-on" ordering automatically.
- A bindable properties class for type-safe configuration.

See gh-947

Automatically apply @EnableJMS when spring-jms is on the classpath
and the annotation hasn't already been applied. This allow for Spring's
new @JmsListener annotation to just work.

Fixes gh-1425

Add `spring.datasource.jndi-name` property to allow a DataSource to be
looked up from JNDI as an alternative to defining a URL connection.

Fixes gh-989

Update JmsAutoConfiguration to inject any PlatformTransactionManager
bean into the DefaultJmsListenerContainerFactory.

Fixes gh-1444

Update JmsAutoConfiguration to inject any existing DestinationResolver
bean into JmsTemplate and DefaultJmsListenerContainerFactory.

Fixes gh-1443

Fixes #1429

Velocity and Freemarker share some common properties so the base class for
configuring their properties makes some sense. Unfortunately the implementation
pulls in Spring MVC at runtime because of the signature of one method (that
would never be called). We can fix that in a number of ways, but the least
disruptive is probably to change the signature of that method and only refer
to the concrete template view resolver type if the method is called.

Fixes gh-1437

Add the servlet and context path along with the exception message to
the error logged in ErrorPageFilter.

See gh-1427

For some reason I thought that the DispatcherServlet default handler
would log all exceptions, so if we did it in the ErrorPageFilter it
would lead to duplicates. That appears not to be the case.
