patch: add --skip-not-applicable-patches to autoresolve not applicable patches

[mlandres]

(closes #514) The first commits are fixes and enhancements to the patch. The last one introduces the feature.

If multiple problems are to be reported, zypper uses a 1st pass to quickly list all problems and a 2nd pass to ask to resolve each problem.

We use the 1st pass to check for auto-applicable solutions and re-solve if solutions were applied. If problems still remain at the end, we ask.

The draft is basically ready. Remaining tasks:

• [x] Remember skipped patches and show them in the summary.
• [x] Upadte man page.
