Remove third_party/xdg_shared_mime_type

Use base::nix::GetFileMimeType() instead which will read the local copy
of /usr/local/share/mime/mime.cache.

Partial revert of crrev.com/c/3848953.

net::GetMimeTypeFromFile() will now block for ChromeOS, so changed
some callers to use net::GetWellKnownMimeTypeFromExtension() which
does not block and is sufficient for what is required by the caller.

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.
