- Eliminate trailing whitespace

 - Update long method signatures to follow framework whitespace
   conventions

   Based on the following search,

       $ git grep -A3 '^.public .* .*([^\{;]*$' */src/main

   the strong convention throughout the framework when dealing with
   methods having long signatures (i.e. many parameters) is to break
   immediately after the opening paren, indent two tabs deeper and break
   lines around 90 characters as necessary. Such signatures should also
   be followed by a newline after the opening curly brace to break
   things up visually.

   The files edited in this commit had a particularly different style of
   intenting arguments to align with each other vertically, but the
   alignment only worked if one's tabstop is set at four spaces.
   When viewed at a different tabstop value, the effect is is jarring,
   both in that it is misaligned and significantly different from most
   of the framework. The convention described above reads well at any
   tabstop value.

This change makes the HttpServletResponse available to the methods
of FlashMapManager in addition to the HttpServletRequest.

Before this change, flash attributes could only be added if via
RedirectAttributes.addFlashAttribute(..) if the method returned
a view name or a View instance. With this change, the above is
supported with a ModelAndView return value as well.

Hibernate exception translation covers NonUniqueObjectException to DuplicateKeyException case (SPR-8996)

Cannot yet actually reproduce the issue, but this remains a useful
test case.

Issue: SPR-8934

Prior to this change, the spring-cache XSD allowed a 'key-generator'
attribute, but it was not actually parsed by AnnotationDrivenCacheBDP.

This commit adds the parsing logic as originally intended and the test
to prove it.

Issue: SPR-8939

Prior to this change, the caching reference docs referred to
'root.params', whereas the actual naming should be 'root.args'. This
naming was also reflected in the "#p" syntax for specifying method args.

This change updates the documentation to refer to 'root.args' properly
and also adds "#a" syntax for specifying method arguments more
intuitively. Note that "#p" syntax remains in place as an alias for
backward compatibility.

Complete pass with `dos2unix` found additional files missed on earlier
related commit.

Issue: SPR-5608

added protected "isPersistenceUnitOverrideAllowed()" method to DefaultPersistenceUnitManager (SPR-8925)

Hibernate synchronization properly unbinds Session even in case of afterCompletion exception (SPR-8757)

officially deprecated TopLinkJpaDialect in favor of EclipseLink and Spring's EclipseLinkJpaDialect; updated supported version ranges for EclipseLink and OpenJPA

Hibernate 4 LocalSessionFactoryBean implements PersistenceExceptionTranslator interface as well (SPR-8952); consistent extending of HibernateExceptionTranslator for Hibernate 3 as well as Hibernate 4

Prior to this change, roughly 5% (~300 out of 6000+) of files under the
source tree had CRLF line endings as opposed to the majority which have
LF endings.

This change normalizes these files to LF for consistency going forward.

Command used:

$ git ls-files | xargs file | grep CRLF | cut -d":" -f1 | xargs dos2unix
