Description:
Updated to 1.6.34, stripped all unneeded files.

- Use custom configuration file pnglibconf.h, which turns off all features that
  are not in use.
- Use custom prefix file pngprefix.h, which avoids namespace conflicts with
  pdfium's copy of libpng.
- Configures custom png chunk user limits (crbug.com/117369) in pnglibconf.h.
- Modify png_check_chunk_length to call png_benign_error instead of
  png_chunk_error. (crbug.com/827754)
