HibernateJpaDialect prepares JDBC Connection by default if on Hibernate EntityManager 4 (with its connection release mode ON_CLOSE)

Analogous to HibernateTransactionManager, there is a "prepareConnection" flag on HibernateJpaDialect which allows for overriding the actual mode of operation. This is easily accessible from HibernateJpaVendorAdapter now which declares HibernateJpaDialect from its getJpaDialect() method.

 - Fix Javadoc in HibernateTemplate so that it compiles in Eclipse.
 - Suppress generics warnings in HibernateTemplateTests.
 - Remove unnecessary deprecation warning suppression in constructor for
   LocalSessionFactoryBuilder.

Issue: SPR-11291

Note that this variant of HibernateTemplate is stripped down in terms of Session management options and just provides a current-session style with a fallback to a temporary session-per-operation.  Furthermore, in the latter fallback mode, only read operations are supported, just like with a JPA EntityManager.

Fix remaining Java compiler warnings, mainly around missing
generics or deprecated code.

Also add the `-Werror` compiler option to ensure that any future
warnings will fail the build.

This change adds async web request timeout handling to OSIV filters

Uses Object-typed setter methods to bridge between package location changes in Hibernate 4.2 vs 4.3. As a side bonus, those setters accept Class and class names as well.

Issue: SPR-10823

Due to key SPI interfaces such as ConnectionProvider and JtaPlatform changing their package location in Hibernate 4.3, we have to resort to reflection in a few places. Most importantly, the ConfigurableJtaPlatform used by the setJtaTransactionManager method has now been redesigned as a reflective proxy.
