header (C) fixes
Automated rebranding to Oracle copyright/license strings via filemuncher
IPRT,HostDrv,AddDrv: Export public IPRT symbols for the linux kernel (pain).
Runtime: small fix to the UUID code, splitting the ClockSeq field and put the UUID variant in the right place. Rest is cleanup and documenting that the IPRT UUIDs are little endian.
Opps, left some @todos behind.
Split out RTUuidCreate, so we don't drag in RTRand when we don't need to create UUIDs.
