Integrate bisection search with javafuzz

This CL makes javafuzz call bisection search on failing tests.

Three switches were added to bisection_search, --logfile which can be
used to provide custom logfile destination, --never-clean which
disables automatic cleanup of bisection directory and --timeout
which allows user to specify maximum time in seconds to wait for
a single test run.

ITestEnv subclasses were updated to integrate with javafuzz.

run_java_fuzz_test.py is now reusing code from bisection_search
module. It also better matches python style guidelines.
