Andrew Johnson 3c99391d93 Added SPDX License ID to all EPICS-original source files
In some cases the license-identification header was missing,
so I added that as well. Replaced the remaining headers that
specifically identified "Versions 3.13.7 and higher".

Makefiles and the build system were deliberately excluded.
