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.
Exception specifications are deprecated: http://isocpp.github.io/
CppCoreGuidelines/CppCoreGuidelines.html#e30-dont-use-exception-
specifications . They will be removed from the C++ standard with
C++20. Modern compilers are warning about them since years. Thus
it's unlikely that anyone is still using the epicsThrows() macro.
Even if that's the case the fix is trivial: Simply remove the macro.
