add support for back end fnmatch'd options

This is work originally provided by Sascha Kruse on FS#20360 with only
minor adjustments to the implementation. It's been expanded to cover:
NoUpgrade, NoExtract, IgnorePkg, IgnoreGroup.

Adds tests ignore008, sync139, sync502, and sync503.

Also satisfies FS#18988.
