Previously, MetaInfResourceManager that we use with Undertow to serve
static resources from jar's META-INF/resources did not correctly
handle characters in the path that should be percent-encoded when
used in a URL.

This commit updates MetaInfResourceManager to encode the path before
it is used to create a URL. Prior to this encoding, encoded slashes
(%2F) are decoded as, unlike other encoded characters in the request's
URL, encoded slashes are not decoded prior to calling the
ResourceManager.

This commit also changes the request matcher for MVC
endpoints to use an AntPathRequestMatcher instead of an
MvcRequestMatcher. The endpoint is always available
under the mapped endpoint path and this way the same matcher
can be used for both MVC and Jersey.
