This patch adds the file_writer header, which just provides a wrapper
for File->write, as well as fprintf to use it. There are no unit tests
for file_writer since it's too simple to need them, but fprintf does
have a simple test of writing to a file. True printf may take a while
longer since stdout is not yet supported, but all the other pieces are
now in place.
