1494369 - GeckoView: Add APIs for visited URLs

Status: RESOLVED DUPLICATE of bug 1494713

(GeckoView :: General, enhancement, P3)

Description

[Sebastian Kaspari (:sebastian; :pocmo)]

We will need two GeckoView APIs:

* (1) GeckoView notifying the app about a visited URL

* (2) The app providing visited URLs to GeckoView in order to do link coloring

Related WebView APIs:
* https://developer.android.com/reference/android/webkit/WebViewClient.html?hl=cs#doUpdateVisitedHistory(android.webkit.WebView,%20java.lang.String,%20boolean)
* https://developer.android.com/reference/android/webkit/WebChromeClient?hl=cs#getVisitedHistory(android.webkit.ValueCallback%3Cjava.lang.String[]%3E)

We talked about this a bit on Slack:

1) Probably don't want to require the app to dump the entirety of its visited link data on us

2) Prefer a callback approach where we ask the app for the status of a given set of links
2a) We think it's probably ok if this is async, meaning the style of links may change after the page has loaded

3) We can apply some LRU cache to lower the number of callbacks and the set of links requested.
