pre-process: print macros containing # and ## correctly
The dump_macro() function fails to correctly output the definitions of
macros that contain the string operator '#', the concatenation operator
'##' and any macro parameter in the definition token list. For example,
the following macros:
#define STRING(x) #x
#define CONCAT(x,y) x ## y
are output like so:
#define STRING(x) unhandled token type '21'
#define CONCAT(x, y) unhandled token type '22' unhandled token type '23' unhandled token type '22'
Add the code necessary to handle those token types to the dump_macros()
function and add the above macros to the 'dump-macros.c' test file.
