Commit 5b1165 was an attempt to leave semicolon content in the URL path
while ignoring it for request mapping purposes. However, it becomes
quite difficult to manage and semicolon content should not always be
ignored (sometimes a semicolon is used as a separator of multiple items
in a path segment, rather than for matrix variables).
This change effectively reverts back to the original approach in 3.2
where a flag on AbstractHandlerMapping can be used to have semicolon
content removed or kept. If kept, path segments with matrix variables
must be represented with a path segment.
The main difference is that by default it is removed everywhere
including the MVC namespace and Java config.
