The variable validator assumes that any AST node it gets from an
interpolation walk is an indicator of an interpolation. Unfortunately,
back in f223be15 we changed the interpolation walker to emit a LiteralNode
as a way to signal that the result is a literal but not identical to the
input due to escapes.
The existence of this issue suggests a bit of a design smell in that the
interpolation walker interface at first glance appears to skip over all
literals, but it actually emits them in this one situation. In the long
run we should perhaps think about whether the abstraction is right here,
but this is a shallow, tactical change that fixes#13001.
golang/tools commit 23ca8a263 changed the format of the leading comment

This is the result of running generate with the latest version of
stringer. Everyone working on Terraform will need to update stringer
after this is merged, to avoid reverting this:

It turns out if you're trying to write a config to conditionally restore
an instance from a snapshot, you end up painted into a corner with the
combination of `snapshot_identifier` and `name`.
You need `name` to be specified for DBs you're creating, but when
`snapshot_identifier` is populated you need it to be blank or else the
AWS API throws an error.
The logical next step is to drop a ternary in:
```tf
resource "aws_db_instance" "foo" {
# ...
snapshot_identifier = "${var.snap}"
name = "${var.snap != "" ? "" : var.dbname}"
}
```
**BUT** the above config will _replace_ the DB on subsequent runs as the
config basically has `name = ""` which will trigger a ForceNew diff once
the `name` is populated from the snapshot restore.
**SO** we can get a workable solution by actively avoiding populating
DBName when we're using one of the engines the docs explicitly mention.
It does not look like there are any tests covering `snapshot_identifer`,
so I'll subject this to some manual tests and follow up with some
results.
Sometimes when waiting on a target state, the set of valid states
through which a value will transition is unknown. This commit adds
support for an empty Pending slice and will treat any states that are not
the target as valid provided the timeouts are not exceeded.
* provider/aws: Deprecate roles in favour of role in iam_instance_profile
You can only specify a single role to an IAM Instance Profile. So having
a slice of roles in the provider makes no sense. Therefore, we are going
to deprecate this infavour of `role`

* Update iam_instance_profile.html.markdown
Adds `basename` and `dirname` interpolation. I want to add a `stack` tag to our infrastructure, the value of which is set to `${basename(path.cwd)}`. We currently use `${replace(path.cwd, "/^.+\\//", "")}` instead, but this is extremeley unreadable. The existance of a `basename` function would be very useful for this use case.
I don't have an immediate use case for a `dirname` function, but it seemed reasonable to add it as well.
