Automatic update from web-platform-testsWeb Locks API: Upstream tests to web-platform-tests (as .tentative) * Move tests from http/tests/locks to external/wpt/web-locks * Name with '.tentative' infix since this is still just a proposal * Name most tests with '.https' infix since feature is [SecureContext] (and remove redirect-to-secure-host logic in tests) * Consolidate window/worker interfaces test with '.any.js' variant * Update paths to service worker helpers Bug: 857265 Change-Id: Iaf254c5d53ff5b6bb65de4516df85307ad3a6519 Reviewed-on: https://chromium-review.googlesource.com/1118764 Commit-Queue: Victor Costan <pwnall@chromium.org> Reviewed-by: Victor Costan <pwnall@chromium.org> Cr-Commit-Position: refs/heads/master@{#573991} -- wpt-commits: 89ccb892ad85159b093dab6956ca9caea7bb4edc wpt-pr: 11713
