Correct wrong ASSERT()s on SetMem16(), SetMem32(), SetMem64() HobLib: Add Missing ASSERT()s for BuildGuidHobData() since CopyMem() now allow zero source buffer with length > 0. BasePrintLib Add ASSERT()s to check NULL buffer and NULL format. PostCodeLib Add 3 instances of PostCodeLib and introduce new Pcd for post code property mask. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@438 6f19259b-4bc3-4df7-8a09-765794883524
