1. Add a newline at the end of test files …

   When running in some settings, a C compiler may demand newlines at the
   end of each file.  Instead of modifying everywhere that writes out test
   files to incorporate newlines in each indivudual string, simply add a
   newline when writing it out.
   
   Only add a newline to the end of the file if there isn't one already
   there.
   
   An examples of when this is a problem is running with `CC=clang` and
   `CFLAGS="--std=c99 -pedantic-errors"` and meson.build contains (for
   example) the following:
   
   ```
   project('myproject', 'c')
   executable('myexecutable', 'main.c')
   cc = meson.get_compiler('c')
   sizeof_int = cc.sizeof('int')
   
   ```
   
   sizeof_int will be -1, because the compile failed.  The meson logs
   contain the error `testfile.c:7:10: error: no newline at end of file`
