Improve performance of Reference processing.
By using synchronization on the ReferenceQueue instead of volatile
modifiers, and adding internal support for ReferenceQueue batch
enqueue and remove.
ReferenceBenchmark improvements on hammerhead:
Alloc 250 => 150
AllocAndEnqueue 1060 => 612
AllocEnqueueAndPoll 1300 => 725
AllocEnqueueAndRemove 1350 => 812
AllocImplicitEnqueueAndRemove 7000 => 1758
Finalization 10000 => 6095

ReferenceQueue.remove() should not time out prematurely
Manually cherrypicked from jdk9, without the associated test.
This tolerates early wakeups from the wait() call, such as when
another thread successfully calls remove.
For the sake if upstream compatibility, we continue to use a separate lock
object for synchronization, though that is probably not really necessary
anymore.

Clean up ReferenceQueue, fix ReferenceQueueTest.
- Remove change markers & clarify comments.
- ReferenceQueue.remove(timeout) doesn't provide any hard guarantees;
it only promises to be broadly equivalent to Object.wait() so there's
no need to wait in a loop. We also guard against "spurious" notifies
by sychronizing on a private object, not on ReferenceQueue.this
(fixes ReferenceQueueTest#testRemoveWithSpuriousNotify).

Further ReferenceQueue fixes.
- Vanilia OpenJdk ReferenceQueue behaves like a stack, this change makes
it behave like a queue.
- Removed internal lock and switched to 'this' for synchronization - tests in
harmony-tests/src/test/java/org/apache/harmony/tests/java/lang/ref/ReferenceQueueTest.java
depend on this behaviour.

Fix ReferenceQueue code (and some test)
ReferenceQueue from OpenJdk needs some more alterations
to work with OpenJdk-but-heavily-modified-to-work-with-our-GC
Reference class.
Updated ReferenceTest#test_subclass test to expect
seems to expect #clear followed by #enqueue, but android
code doesn't call any of them. I need to find someone
knowledgeable to figure out what's the expected behavior).

Use OpenJdk implementation of java.lang.ref.*.
- Daemons: Use enqueue instead of enqueueInternal.
- Reference / ReferenceQueue : Modified to work with ART.

Initial import of OpenJdk files.
Create new libcore/ojluni directory with src/main/java and
src/main/native subdirectiories.
Build ojluni into core-oj jar.
Use openjdk classes from java.awt.font package.
Copy all files from jdk/src/share/classes and jdk/src/solaris/classes
directories in openjdk into libcore/ojluni/src/main/java.
Copy following native files from openjdk to
