James Nugent 47bce79b29 core: Add zipmap interpolation function
This commit adds a new interpolation function, zipmap, which produces a
map given a list of string keys and a list of values of the same length
as the list of keys.

The name comes from the same operation in Clojure (and likely other
functional langauges).

Gustavo 5910e3b8af Adds ‘tittle’ built-in function. (#9087)
The tittle function returns a copy of the string with the first characters of all the words capitalized.

config: ignore_changes cannot have interpolations
This is the limitation of all lifecycle attributes currently. Right now,
interpolations are allowed through and the user ends up thinking it
should work. We should give an error.

In the future it should be possible to support some minimal set of
interpolations (static variables, data sources even perhaps) but for now
let's validate that this doesn't work.

config: fix a conflicting test name
A public API TestNewRawConfig was added to easily create a raw config
for testing, but this conflicted with the test. Just rename it.

config/module: use the raw source as part of the key
This changes the key for the storage to be the _raw_ source from the
module, not the fully expanded source. Example: it'll be a relative path
instead of an absolute path.

This allows the ".terraform/modules" directory to be portable when
moving to other machines. This was a behavior that existed in <= 0.7.2
and was broken with #8398. This amends that and adds a test to verify.

Update reflectwalk to fix failing tests
As part of working on ResourceConfig.DeepCopy, Equal I updated
reflectwalk (to fix some issues in the new functions) but this
introduced more issues in other parts of Terraform. This update fixes
those.

James Bardin a3fc7e2e21 remove "count" while loading a data source
Data sources should be able to support counts like a resource. We need
to remove "count" when we load the config because the key doesn't exist
in the schema, and the resource won't validate.

config: JSON resource keys with only one item load properly GH-5140
When a resource has only a single key set, the HCL parser treats that
key as part of the overall set of object keys. This isn't valid since
we expect resources to have exactly two keys. In this scenario, we have
to "unwrap" the keys back into a set of objects.

James Bardin c15c0eb0cb Disallow strings as arguments to concat
The concat interpolation function now only accepts list arguments.
Strings are no longer supported, for concatenation or appending to
lists. All arguments must be a list, and single elements can be promoted
with the `list` interpolation function.

config: Add map() interpolation function
* `map(key, value, ...)` - Returns a map consisting of the key/value pairs
  specified as arguments. Every odd argument must be a string key, and every
  even argument must have the same type as the other values specified.
  Duplicate keys are not allowed. Examples:
  * `map("hello", "world")`
  * `map("us-east", list("a", "b", "c"), "us-west", list("b", "c", "d"))`

James Bardin 8dcbc0b0a0 Add concat to accept lists of lists and maps
This will allow the concat interpolation function to accept lists of
lists, and lists of maps as well as strings. We still allow bare strings
for backwards compatibility, but remove some of the old comment wording
as it could cause confusion of this function with actual string
concatenation.

Since maps are now supported in the config, this removes the superfluous
(and failing) TestInterpolationFuncConcatListOfMaps.

James Bardin 2bd7cfd5fe Expand list interpolation to lists and maps
Allow lists and maps within the list interpolation function via variable

we check for non-heterogeneous lists in the callback.

James Nugent 58dd41f3b1 core: Add list() interpolation function
The list() interpolation function provides a way to add support for list
literals (of strings) to HIL without having to invent new syntax for it
and modify the HIL parser.

It presents as a function, thus:

    - list() -> []
    - list("a") -> ["a"]
    - list("a", "b") -> ["a", "b"]

Thanks to @wr0ngway for the idea of this approach, fixes #7460.

James Nugent c6e03cba96 core: Fix slice element keys on interpolateWalk
Part of the interpolation walk is to detect keys which involve computed
values and therefore cannot be resolved at this time. The interplation
walker keeps sufficient state to be able to populate the ResourceConfig
with a slice of such keys.

Previously they didn't take slice indexes into account, so in the
following case:

```
"services": []interface{}{
    map[string]interface{}{
        "elb": "___something computed___",
    },
    map[string]interface{}{
        "elb": "___something else computed___",
    },
    map[string]interface{}{
        "elb": "not computed",
    },
}
```

Unknown keys would be populated as follows:

```
services.elb
services.elb
```

This is not sufficient information to be useful, as it is impossible to
distinguish which of the `services.elb`s are unknown vs not.

This commit therefore retains the slice indexes as part of the key for
unknown keys - producing for the example above:

```
services.0.elb
services.1.elb
```

James Bardin 558e023e26 Don't try to copy files over themselves
When copying a config module, make sure the full path for src and dst

different path to the same file.

Make a note about the unsafe usage of reusing a tempDir path.
