Pull over two fixes from FreeBSD

SingleLock.h
Do not create copy of CCriticalSection for each CSingleLock instance

Use reference to CCriticalSection as a CSingleLock member. Otherwise
assignment operator just byte-copies content of CCriticalSection
and for each copy destructor will destroy mutex which may lead
to undefined behaviour

OMXThread.cpp
Fix order of operations on pthread attribute: init first, then modify

Bump PKGREVISION
