The subtle difference in keywords when creating vs. accessing locals trips
people up, even more than the "variable" vs. "var" distinction. It deserves its
own subheader on the page, plus a nice noisy callout.
I've just wasted an hour to two hours trying to find the problem to finally realize that although I declare a "locals" block, it's referred to as "local". This is pretty weird! So let's be be clear about this.
We previously had this just stubbed out because it was a stretch goal for
the v0.13.0 release and it ultimately didn't make it in.
Here we fill out the existing stub -- with a minor change to its interface
so it can access credentials -- with a client implementation that is
compatible with the directory structure produced by the
"terraform providers mirror" subcommand, were the result to be published
on a static file server.

- Add index link as 'overview' (header links are semi-invisible)
- move providers/overview.html to providers/index.html
- Edits to providers overview
- fix filename of os-arch
- edits to provider publishing
Terraform's design assumes that each remote object in Terraform's care is
bound to one resource instance and one alone. If the same object is bound
to multiple instances then confusing behavior will often result, such as
two resource configurations competing to update a single object, or
objects being "left behind" when all existing Terraform deployments are
destroyed.
This assumption was previously only implied, though. This change is an
attempt to be more explicit about it, although these are additions to some
older documentation sections that have not been revised for some time and
so this is just a best effort to make this information discoverable
without getting drawn into a full-on reorganization of these sections.
While revising this there were some particular oddities that I decided to
revise while I was there, but I'll leave a fuller revision of this older
content for a later commit when we have more time to review it in greater
detail.
* Make sidebar nav in language docs more intuitive
* Minor display fixes for registry docs
* Explain providers in the registry in the providers index
* Revise a bunch of language docs around provider reqs
This is mostly an effort to smooth out some of the explanations, make sure
things are presented in a helpful order, make sure terminology lines up, draw
connections between related concepts, make default behavior more apparent, and
the like. It shouldn't include very much new information, but there might be one
or two things that came out of a conversation somewhere.

As part of documenting the new module for_each capabilities we added a
section noting that shared modules using the legacy pattern of declaring
their own provider configurations would not be compatible with them.
However, that also applies to the new module depends_on and several folks
participating in the beta pointed out that the documentation wasn't
discussing that at all.
In order to generalize the advice, I've moved the old content we had
(since v0.11) recommending against provider configurations in shared
modules out into its own section, now being more explicit that it is
a legacy pattern and not recommended, and then folded the content about
for_each and count, now also including depends_on, into that expanded
section.
As is often the case, that had some knock-on effects on the content on
the rest of this page, so there's some general editing and reorganization
here. In particular, I moved the "Multiple Instances of a Module" section
much further up the page because it's content relevant to users of
shared modules, while the later content on this page is more aimed at
authors of shared modules, including the new section about the legacy
pattern.
