Add RESTRICT_NETWORKING to allow disabling network restrictions
Fix stage orphans false positives for some ports using kdeprefix.

Tested on multimedia/phonon
Add new option: PORTTESTING_FATAL
When set to 'no', ports with test failure (violation, orphans or leftovers) will be marked as failed but still packaged to permit testing dependent ports.
This can be useful when doing a bulk -t -a to not have thousands of ports skipped.
The default behavior doesn't change.
Add missing default for COMMIT_PACKAGES_ON_FAILURE
Non-trivial merge with trunk
