RFR: JDK-8282700: Properly handle several --without options during configure

[Julian Waters]

Some of the --without options are not properly handled and will crash when processed (For example, --without-version-string), in other cases the --without-* option will actually silently produce incorrect results instead of actually doing what --without-* implies (For example, --without-build-user and all the --with-vendor-* options). The most elegant way to solve this would simply be to handle such cases and display warnings when they're encountered (or if the option is critical to the build process, throwing an error)

This is an initial change and I may have missed several options; I'll double check and make sure in the meantime
