Merge branch 'policy-CMP0022-fixes' into policy-CMP0022-fixes-for-master
Resolve conflict in Source/cmTarget.cxx by integrating the changes to the internal copy constructor from both sides. Also resolve a logical conflict by dropping the special case for INTERFACE_LIBRARY targets. Since cmTarget::SetMakefile already forces CMP0022 to NEW for such targets we need no special handling. Resolve conflict in Source/cmTargetLinkLibrariesCommand.h by dropping the documentation change. We will make the same change in the new location of the same documentation in a separate commit. Resolve conflicts in Tests/RunCMake/CMP0022/CMP0022-WARN-empty-old-stderr.txt Tests/RunCMake/CMP0022/RunCMakeTest.cmake by taking the side from the 'policy-CMP0022-fixes' branch.
