This CL updates FPDF_LIBRARY_CONFIG to version 6, introducing an experimental m_BrotliEnabled flag. This allows applications to dynamically enable or disable /BrotliDecode at library initialization time when PDFium is compiled with Brotli support. Other codepaths check if Brotli is enabled before decoding brotli-encoded streams. Bug: 475855993 Change-Id: I4ef555dfc58581bae0289c293d2f77a387749637 Reviewed-on: https://pdfium-review.googlesource.com/c/pdfium/+/149610 Reviewed-by: Andy Phan <andyphan@chromium.org> Commit-Queue: Aryan Krishnan <aryankrishnan4b@gmail.com> Reviewed-by: Lei Zhang <thestig@chromium.org>
