Trigraphs such as "??=" (which are enabled by default with -std=c11) can mess up strings, so avoid them entirely by escaping question marks. This also drops Python 2 compatibility from file2string, making the change to the waf rule necessary. The input file is now opened in binary mode which is also more correct versus the old text mode which just happened to work even on binary files.
