the Jacoco agent version to 0.7.5.

The WebContentGenerator now maintains an additional property that
sub-classes can use for an "Allow" header in response to an HTTP
OPTIONS request. This property is pre-initialized once at startup
and does not have to rely on getSupportedMethods in addition to
adding HTTP OPTIONS if not explicitly listed.

AbstractJackson2HttpMessageConverter now implements its own
TypeVariable resolution algorithm since in Jackson 2.7 it is now
deprecated and has not the same behavior .
See https://github.com/FasterXML/jackson-databind/issues/1087
for more details.

The dependency on jackson-datatype-jdk7 has been removed since
it is now provided by default in the jackson-databind module.

This commit updates the javadoc of
`RequestMappingHanderAdapter.setCacheSecondsForSessionAttributeHandlers`
to explain how one can disable that feature and prevent "Cache-Control"
directives from being added when `@SessionAttributes` annotations are
used on Controllers.

Prior to this change, configuring a `FixedVersionStrategy` like so
would configure a single "/js/**" path pattern:

```
versionResourceResolver.addFixedVersionStrategy("v1.0.0","/js/**");
```

This commit makes sure that for each path pattern, its prefixed version
is added to the map. For example, the previous configuration also
adds "/v1.0.0/js/**".
