include: Add a variadic macro to call a callback for all arguments
Add a header variadic-macro.h which defines the CALL_MACRO_FOR_EACH marco.
This macro can be used as follows:
#define TEST(x)
CALL_MACRO_FOR_EACH(TEST, a, b, c, d)
This will expand to
TEST(a) TEST(b) TEST(c) TEST(d)
The nice thing is that CALL_MACRO_FOR_EACH is a variadic macro, thus the
number of arguments can vary (although it has an upper limit - in this
implementation 32 arguments).
