* Indirect stringification.

* Doing two levels allows the parameter to be a macro itself.
* For example, compile with `-DFOO=bar`, `STRINGIFY(FOO)` converts to "bar".
*
* \param x will be converted to one string, including the spaces and commas between arguments.
* For example `STRINGIFY( a , b )` will be expanded to "a , b".
