For libsystemd's headers, the changes made depend on whether the header is installed or not. For installed headers, the only change made is that commonly included headers were moved to _sd-common.h. For these headers, there should be no noticeable change in behavior when including them. For non-installed headers, includes were replaced with forward declarations where possible as usual. Split out of #37344.
