Bug 1088: Add GLRendererQuirks.NeedSharedObjectSync; Tests: Synchronize GL objects if GLRendererQuirks.NeedSharedObjectSync is set.

GLSharedContextSetter#synchronization GL Object Synchronization

Usually synchronization of shared GL objects should not be required,
if the shared GL objects are created and immutable before concurrent usage.

However, using drivers exposing GLRendererQuirks.NeedSharedObjectSync
always require the user to synchronize access of shared GL objects.

Synchronization can be avoided if accessing the shared GL objects
exclusively via a queue or com.jogamp.common.util.Ringbuffer,
see GLMediaPlayerImpl as an example.

+++

GLRendererQuirks.NeedSharedObjectSync is set for all OSX versions

+++

Handle GLRendererQuirks.NeedSharedObjectSync in user code!

+++

All shared context tests passed on OSX 10.9.5,
and GNU/Linux w/ Nvidia + Mesa/AMD driver.
