Added a LRU memory cache for disk-based shared dictionaries

This adds a tunable LRU memory cache for shared dictionaries that are
stored on disk.

Specifically, it allows for any request to match from the cache but
limits writes to the cache to navigation-style requests (documents and
frames) where dictionaries are likely to be reused but not in such a way
that they benefit from the existing ref-counted cache.

It also adds a histogram to track the cache hit rate for document
requests to help with the tuning of the cache size.

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.
