Update std.array to use new REF macro

[JakobOvrum]

Depends on dlang/dlang.org/pull/1184.

Just an example to show how to use it for now.

rebase

[JakobOvrum]

Don't merge this until the dependency is merged.

@JakobOvrum Time to rebase?

[JakobOvrum]

Rebased. The only real diff stems from the use of ROOT_DIR, which I'd say is a good sign that it works as a drop-in replacement.

The choice of std.array for this PR was fairly abitrary. I recently filed #3926 which applies MREF across all of Phobos. I'd like to convert this PR into one that similarly applies REF across all of Phobos (if we go ahead with that, it would help if #3926 was merged first, as it gets rid of many uses of LINK2). Thoughts?

Note that any macros in dlang.org.ddoc cannot be removed until they are verified to be unused across all three repositories.

Thanks, hurray for relative links.

[JakobOvrum]

OK, I'll file future changes in a new PR then.

Sorry, I somehow skipped over this paragraph:

AFAICT this was just a proposal, so it can be closed?

@JakobOvrum otherwise please rebase :)

[quickfur]

Now that dlang/dlang.org#1257 has merged, is this ready to go?

Also, merge conflict; please rebase.

[JakobOvrum]

If you'd like to help with this effort, please look at #3926.

Thanks to @aG0aep6G's efforts XREF got replaced with REF :)

Hence this is show case PR is not needed anymore.
