This commit changes the solr health indicator to request the status of
all available cores, rather than invoking a generic ping on the admin
handler.
Recent versions of Solr now have a ping handler per core and the general
admin handler is gone, leading to incorrect health status. For backward
compatible reason the `solrStatus` attribute is kept to `OK` if all cores
are running properly (that's actually `0` behind the scenes).

Previously, jars (either top-level or nested) in Zip64 format were
treated as normal jar files. This would lead to a failure later on
when an attempt was made to read an entry from the file.
This commit updates the loader to fail fast when it encounters a
Zip64 jar file. Such files are identified by the number of entries
in the central directory end record being 0xFFFF.

Previously, WelcomePageHandlerMapping would forward to index.html.
This assumed that the static path pattern was always /**. If it had
been customised to, for example, /foo/**, then the forward would still
be to index.html and a 404 would result as the page is actually
available at /foo/index.html.
At first glance, it would appear that the forward should be made to
foo/index.html. However, as it's a forward rather than a redirect,
any relative URLs in the index.html page would then be resolved using
/ whereas they should be resolved using /foo/. This could be addressed
by using a redirect rather than a forward, but we don't want to do
that as it's more invasive and would require a roundtrip back to the
client. Instead, this commit simply stops performing the forward when
the static path pattern is not /**.
