Revert "Use base::cstring_view in base::Environment"

This reverts commit 197604a7e5581884f8d017a1eca88a5070bac89d.

Reason for revert: Causes compile failure on linux64-rel-ready builder:
See https://ci.chromium.org/ui/p/chrome/builders/ci/linux64-rel-ready/46753/ and subsequent builds.

Original change's description:
> Use base::cstring_view in base::Environment
>
> Before this change, it was possible to pass a string that didn't
> have a terminating null character. To account for this, some of the
> functions created a temporary std::string, nullifying the point of
> the string_view. In addition, this temporary std::string was not
> created in every function.
>
> This is now fixed by using base::cstring_view.
>
> This change required modifying a couple existing constants to be
> fully defined at the call site.

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.
