Set PDF to SAMPLED_PING

This file type is a huge amount of traffic but a very small amount of
warnings. It's not a good tradeoff to be sending download pings for
this file type. By setting it's file type policy to SAMPLED_PING, we
will only contact Safe Browsing about a small fraction of downloads.
This preserves some visibility (in case we need to revert this),
without paying the ongoing cost of delaying user downloads.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
