Performance: reduce TLS overhead of QGLContext::currentContext()
The handling for the current QGLContext was looking up the same
TLS data several times per call (hasLocalData() and localData()
calls particularly).
This change also refactors the code a little so that the
setting of the QGLContext within makeCurrent() and doneCurrent()
is in one location in the code instead of six (one per platform).
