Add sample profiling interface to startMethodTracing.

Libcore side of this change. Also changed art and frameworks base.

Speed-up for apps that use Dagger on ART

This is more of a harm-free heuristic improvement than a fix.
It rearranges the algorithm for determining whether a Field
(or Constructor/Method) is annotated. A cheap check (does the
Field/Method/Constructor has any annotations at all?) is pushed
ahead of a more expensive one (If the annotation were to be
present, what would its type index be?). This happens to work
well in practice in sample apps because the cheap check often
fails, allowing the algorithm to terminate earlier.

The second change is to skip() the field information
rather than to read each field in turn when looking for Method
or Constructor annotation information.

The second change is not a hotspot but looks like an easy
optimization that avoids many small method calls and a for
loop for little additional complexity.

Improve URI.equals performance.

The main improvement is that we're vastly reducing
the amount of garbage this method creates.

Also, get rid of some incorrect checks and add a new
benchmark test case.

Before vs. After:

URI                            Equals     1540.1 =
URI EqualsWithHeavilyEscapedComponent 11921397.1 ==============================

URI                            Equals     1337.2 =

Fix several decoder bugs.

- NativeConverter should report unterminated character
  sequences to managed code.
- CharsetDecoderIcu should report those errors correctly
  from flush()
- InputStreamReader should check the return value of
  flush() and not ignore it altogether.

Fix CTS test failure under ART

The Thread.interrupted() State from
SelectorTest.testInterrupted() was leaking into
SelectorTest.testManyWakeupCallsTriggerOnlyOneWakeup() causing
that test to fail when the CTS was run with the ART. Under
Dalvik the "interrupted" state was being reset, but it was
causing the test runner to run each subsequent test in its
own Dalvik instance (which probably slowed down the tests but
wasn't causing failures).

It is unclear why a Thread being in "interrupted" after a test
does not cause problems for ART in the same way it causes
problems for Dalvik.

Switch Random to use AtomicLong

This removes the synchronization from next() and replaces the seed with
an AtomicLong.

Improve detection of CloseGuard protected resource leakage

* Add CloseGuardMonitor to intercept and collate CloseGuard reports and if
  necessary throw an exception listing the resource leaks.
* Add ResourceLeakageDetector to abstract away the CloseGuardMonitor which will
  not work on RI.
* Add AbstractResourceLeakageDetectorTestCase as a base class for tests
  that need to detect resource leaks, in future this could be handled by
  modifications to Cts and Vogar test runners.
* Remove CloseGuardTester and its sole usage in ProcessBuilderTest.
* Remove CloseGuardGuard from within URLConnectionTest
* Change ZipFileTest, ZipInputStreamTest, ZipOutputStreamTest,
  ProcessBuilderTest, URLConnectionTest to use new mechanism, fix issues that
  are identified and do some cleanup/remove duplicated code.
