Subject: [PATCH] DPL: work around for dependency on DPL::Thread

Patch based on work by similar work by Zofia Abramowska.
Include needed parts from DPL::Thread into code of
NaiveSynchronizationObject.
Only NanoSleep() and MiliSleep() methods are needed and the original
DPL::Thread() triggers a large chain of dependencies, including EFL.
