Upgrade adblockplus core for anti-circumvention and snippets hg:bec7c35902d3

[hfiguiere]

Background

To bring both the anti-circumvention list and the snippets we should upgrade the dependency on adblockplus core to hg:bec7c35902d3

Also we must update adblockplusui to hg:9a652397b9af for a dependency between #6559 and #6739.

Here are the changes for adblockpluscore:

• Issue #6690 - Always ignore trailing dot in document domain
• Issue #6737 - Use String.includes instead of String.indexOf
• Issue #6559 - Use Map object for known subscriptions
• Issue #6559 - Change SpecialSubscription.defaultsMap to Map object
• Issue #6735 - Store domains in lower case
• Issue #6619 - Qualify CSS selectors in document style sheet correctly
• Issue #6727 - Use string rather than map for single-domain filters
• Issue #6437 - Skip elements not affected by DOM mutations
• Issue #6689 - Add type property to Subscription class
• Issue #6689 - Added anti-CV filter list subscription
• Issue #6538, #6781 - Add snippets
• Issue #6733 - Allow empty values in filter options

Here is the change for adblockplusui:

• Issue #6739 - Adapted code to work with Map implementation of FilterStorage.knownSubscriptions

What to change

Update the dependencies file to pull adblockpluscore hg:bec7c35902d3, and adblockplusui hg:9a652397b9af

Hint for testers

TBD (a lot of things)

We need to update adblockplusui at the same time to get https://issues.adblockplus.org/ticket/6739 that is required.

I discussed that with Winsley before. Right after the 3.2 release, #6739 (and only this change) will be merged in the adblockplusui Mercurial repository (they do their development on GitLab and only merge stuff to Mercurial for us to integrate). Then we can update adblockpluscore to the latest revision, and simultaneously update the adblockplusui dependency without pulling in unrelated UI changes at the same time, while not breaking anytinhg (hopefully).

For reference, #6739 (in adblockplusui) and #6559 (in adblockpluscore) have a mutual depdency, i.e. if those changes aren't pulled in simultaneously things will break.

I looked for one before even filing this one :-(
