Dale Stimson 4e6fe62eb6 Convert FALLTHROUGH comments to C++17 [[fallthrough]] attribute
Use conditionals and a macro to avoid provoking compilers that do
not support this attribute.

Adds a macro named CPP_ATTRIBUTE_FALLTHROUGH which is invoked right
before a following case statement to declare that the intent is to
fall through.  Example:

    ...
    case xxx:
       ...
       CPP_ATTRIBUTE_FALLTHROUGH;
    case yyy:
    ...

The gcc/clang alternative of adding comments that contain "FALLTHROUGH"
suffers from the problem that *by default* ccache strips the comments
so that they are not present for the real compilation.
