Revert a change which was wrong in class pluglist.

issue #6114

Removed phpstan.neon which will be in dev-tools instead.
Fixed some phpstan reported problems to avoid having a huge baseline.

issue #6114

Use a thrown error instead of calling msg_dialog and exit.
And use an exception handler to format uncaught fatal errors.

issue #6071

msgPool always returns escaped string because it may be used from
 smarty.
htmlescape now calls htmlspecialchars instead of htmlentities, allowing
 to escape strings with % without losing sprintf capability.

Removed print_header function which was doing two different things and
 misused in some places.
