Patch for 4.2.1.

It occurred to me that people might wonder what this patch actually does :-).

On object load the MIME field data for the WKS index, the presence bits, and the accelerators is recomputed using the current values. This should fix the crashes which are due to these values being out of sync with the fields. This is only done for caches with a version of 23.0 which is the version for 4.0 through 4.2.0. This patch bumps the minor version so that if the cache is cleared, the version will be 23.1 and the recomputation will not be done.

This fix up can be forcibly disabled by setting the value to 0 for

proxy.config.cache.http.compatibility.4-2-0-fixup
