Changeset 53803 for trunk/tests/phpunit/tests/filters.php

Message:

Plugins: Introduce did_filter() function.

While most of the action functions are aliases for the respective filter functions, using did_action() to detect whether a filter has been run is not possible, as it only works specifically for actions.

This is now resolved by introducing a new function, did_filter(), which retrieves the number of times a filter has been applied during the current request, bringing parity with did_action().

Follow-up to [4630], [6318], [27294].

Props mordauk, chriscct7, andykeith, nacin, dd32, markparnell, SergeyBiryukov.
Fixes #35357.
