Android: Re-enable threaded rendering

In Qt 5.2.x, the platform plugin inherited from the EGLFS platform
plugin, so calling the super class implementation of hasCapability()
would return true for ThreadedOpenGL. Since this link was removed
in Qt 5.3, we would return false for all devices, giving us a large
performance regression.

Android: Check for exception before calling NewGlobalRef().

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.

make -separate-debug-info configure tests sane

as the option needs to be explicitly requested, just error out when
objcopy is bad.
also, disabling it after performing the test successfully isn't a very
clever thing to do. hpux is dead anyway, so just remove that logic.

make -separate-debug-info sane

don't make it add -g flags all of its own, but instead rely on debug
info being already present.

Return false on context creation failure

Make QOpenGLContext::create() return false when the native context
could not be initialized. This way the return value and isValid()
become equivalent.

Relying on on having a non-NULL platform context is not enough, many
platforms will return a new instance even if the underlying platform
code failed to create a native context. To ensure that a platform
context is really usable, isValid() has to be checked too.

Desktop OpenGL has GL_UNPACK_ROW_LENGTH which we

This removes the need to call QImage::copy(). On

of the total run time by 1-4%. (on tests/manual/
