Some functions, like `patch_init_rc()`, treat buffers read into memory as a string instead of a byte buffer. Since the buffers weren't NULL-terminated, this resulted in out-of-bounds reads and caused crashes in certain conditions. THis commit updates fd_full_read() to always NULL-terminate the buffers so that they can be treated as strings when working with text files. Signed-off-by: Andrew Gunnerson <andrewgunnerson@gmail.com>
