domatolpm: reduce compile time by breaking proto definitions

This CL introduces a new feature in DomatoLPM where proto definitions
are broken into multiple proto files.

To achieve that, we're using Tarjan's algorithm to find strongly
connected components in the proto definitions graph. Once those
components are found, we merge them to split into the desired number of
proto files. Big components are unfortunately non-mergeable.

This CL will allow merging the WebIDL fuzzer back.

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.

If you found a bug, please file it at https://crbug.com/new.
