Detect and fix resource leakages in tests
Tests that test those classes that use CloseGuard to detect
reosurce leakages are switched to use TestCaseWithRules and
ResourceLeakageDetector.getRule() to detect any resource
leakages and the leaks fixed.
A number of tests could not be fixed due to bugs in the core
classes so a new DisableResourceLeakageDetection annotation was
added as part of this change. A method annotated with that does
not perform resource leakage detection. The affected tests were
annotated with a description and a reference to an associated
bug.
This uses try-with-resources to aid in closing resources. While
that does provide some benefits it is all too easy to change the
behavior of the test unless care is taken. To avoid that it is
important not to merge it with an existing try block such as
those which follow the following pattern:
try {... fail()} catch(..) {}
Merging them could result in the test catching and ignoring
exceptions thrown during the creation of the resource which is
almost certainly not what the test was intending.
Test: Tested with vogar and CTS
