Kartikaya Gupta 32f767413d Bug 695170 - Implement visited link styles [r=blassey]
Provide an IHistory interface implementation from the android widgets
rather than using the one in Places. This allows the Link class to get
history information from the android code. The IHistory implementation
talks to the Android browser history database via JNI.
The Java-side implementation attempts to batch-process the requests coming
in, and keeps an in-memory cache of the visited links to avoid multiple
hits to the database. The in-memory cache is guaranteed to be cleared
by the VM before an OOMs get thrown.
The current implementation does not consider external events that might
update the history database, and so the visited link information
provided to Gecko might not reflect the latest information in the
Android browser history database.
