Prior to this commit, the getter methods in MockServletContext threw an
UnsupportedOperationException when trying to retrieve Servlet and
Filter registrations.

This commit improves the behavior of these methods by returning null
when a single registration is requested and an empty map when all
registrations are requested. This is now in line with the Javadoc for
ServletContext. Note, however, that the corresponding setter methods
still throw UnsupportedOperationExceptions which is suitable behavior
for a mock.

* typofix:
  fix typo

The ternary expression node was failing to generate the
necessary unboxing bytecode when the condition part
of the expression returned a boxed Boolean rather than
a primitive boolean.

Also fixed here is an IllegalAccessError that was
seen in the same expression due to generating a
CHECKCAST bytecode for a private type.

Prior to this commit, the ResolvableType static cache was holding a lot
of duplicates for simple types. We are using too much metadata to compute
the key when the class has no generic information. so setFoo(String foo)
and setBar(String bar) would result in two entries in the cache because
the TypeProvider is different. On a very simple application 65% of the
entries in the cache were duplicate.

When the type is a Class with no generic information, the ResolvableType
instance is a simple wrapper around it so we might just as well not cache
it at all as the cost of finding it back from the cache is higher than
creating that simple wrapper.

This commit adds an explicit check; if the type is a simple Class we just
return a "resolved" ResolvableType instance for it. On a few test cases,
this reduces the size of the cache by 85%

 - clean up warnings
 - simplify ApplicationContext configuration

The ViewResolverComposite that contains the ViewResolver's registered
throug the MVC Java config and namespace can now be assigned an
explicit order.

The MVC Java config and namespace now have a consistent default order
or lowest precedence.

Prior to this commit, `AntPathMatcher.extractPathWithinPattern` would
not process correctly `**` patterns and would only match *one* path
segment in the given path.

This commit changes `extractPathWithinPattern` to allow multiple path
segments to be matched against a single `**` pattern segment.

Jackson2ObjectMapperBuilder now allows to create ObjectMapper and XmlMapper
instances easily thanks to its fluent API.

This builder is used in Jackson message converters and views to instantiate default
ObjectMapper and XmlMapper.

This commit also add a createXmlMapper property to
Jackson2ObjectMapperFactoryBean in order to allow to create easily a XmlMapper
instance.
