std::memcpy -> memcpy for instance. This change was motivated by a
compile report complaining that std::rand() was used instead of rand(),
probably with a stdlib.h include instead of cstdlib. Use of C functions
without the std:: prefix is a lot more common, so removing std:: to
address this.

Android's JVM requires threads to detach before they exit, but ONLY if
they needed to AttachCurrentThread. Conversly, threads that were
attached by the JVM (e.g. the result of making a native call from Java)
must NOT be detached by the application. This is bug 2441.
The fix for the above is to only pthread_setspecific() for threads that
Attach(), not for already-attached threads. To ensure that we only
detach Attached threads, added a GetEnv() call to ThreadDestructor(),
which revealed that Oracle's JVM can overly-eagerly clear TLS accounting
data, effectively detaching threads without their consent at shutdown.
Work around this with a specific check.
To guard against (some) regression, added a variant of PeerConnectionTest
that runs on a non-main thread. This revealed a bug in LinuxDeviceManager
which implicitly assumes its talk_base::Thread has already been
initialized. Fixed that here too.

1) init start_time_ns_ before the file_read_thread_ is started to avoid data racing as the start_time_ns_ will also be read by the file_read_thread_.
2) add CriticalSection to protect |finished_| that is accessed by FileReadThread and the main thread
Also remove the suppression for filemediaengine.cc, which has already been fixed in other cl.

Update Thread documentation, fix all subclasses that had a problem.
This is to avoid a data racing between the destructor modifying the vtable, and
Thread::PreRun calling virtual method Run at the same time.
For example:
[ RUN ] FileMediaEngineTest.TestGetCapabilities
