Calling NewGlobalRef() throws an exception if it gets an invalid ref.
If one of the jni object-calls throws an exception and the returned
reference is invalid, the subsequent call to NewGlobalRef() will trigger
the second exception and the process will be terminated.

In some cases the classLoader is not able to resolve fully-qualified
names that contains forward slashes. Unlike FindClass() which expects
the fully-qualified name to contain slashes, the classLoader expects
the binary name, i.e., with '.' as separator.
This caused a crash in QtMultimedia when accessing a nested class.

Attaching and detaching the current thread to/from the VM on each jni call,
causes a new thread object to be created and triggers GC when detaching
(GC alone takes anything between 10-30 ms to finish on the test device).
Instead of detaching when the environment object goes out of scope, we
now detach when the thread exits.

NewObjectV() was failing because QJNIObject was calling the variadic
constructors with a va_list, which in turn created a new va_list.

Previously the system class loader was used, which meant only system
Java classes where available. With this change it's no longer necessary
to add a JNI_OnLoad() to get a handle to application specific classes.

When interfacing with Java API's on Android we need to write code using
the Java Native Interface (JNI). Writing JNI code requires a lot of
boilerplate code to be written. This patch contains API's to minimize the
amount of work needed to write JNI code.
QJNIEnvironmentPrivate:
On creation QJNIEnvironmentPrivate will attach the current running
thread to the Java VM, and expose the java environment.
QJNIObjectPrivate:
Wrapps around a Java class enabling the user to access the class from C++.
