Martin Atkins a67182543c Nicer error when list/map assigned to string argument.
Previous this would return the following sort of error:
expected type 'string', got unconvertible type '[]interface {}'

This is the raw error returned by the underlying mapstructure library.
This is not a helpful error message for anyone who doesn't know Go's
type system, and it exposes Terraform's internals to the UI.

Instead we'll catch these cases before we try to use mapstructure and
return a more straightforward message.

By checking the type before the IsComputed exception this also avoids
a crash caused when the assigned value is a computed list. Otherwise
the list of interpolations is allowed through here and then crashes later
during Diff when the value is not a primitive as expected.

Martin Atkins cc8e8a55de helper/schema: Default hashing function for sets
A common issue with new resource implementations is not considering parts
of a complex structure that's used inside a set, which causes quirky
behavior.

The schema helper has enough information to provide a default reasonable
implementation of a set function that includes all non-computed attributes
in a deterministic way. Here we implement such a function and use it
when no explicit hashing function is provided.

In order to achieve this we encapsulate the construction of the zero
value for a schema in a new method schema.ZeroValue, which allows us to
put the fallback logic to the new default function in a single spot.
It is no longer valid to use &Set{F: schema.Set} and all uses of that
construct should be replaced with schema.ZeroValue().(*Set) .

Paul Hinze a4912cc51f helper/schema: limit ValidateFunc to primitives for now
I couldn't see a simple path get this working for Maps, Sets,
and Lists, so lets land it as a primitive-only schema feature.

I think validation on primitives comprises 80% of the use cases anyways.

Paul Hinze 49352db26f helper/schema: skip ValidateFunc on other errors
Guarantees that the `interface{}` arg to ValidateFunc is the proper
type, allowing implementations to be simpler.

Finish the docstring on `ValidateFunc` to call this out.

Paul Hinze 1e3d1b07e6 helper/schema: validate ConflictsWith against top-level
The runtime impl of ConfictsWith uses Resource.Get(), which makes it
work with any other attribute of the resource - the InternalValidate was
only checking against the local schemaMap though, preventing subResource
from using ConflictsWith properly.

It's a lot of wiring and it's a bit ugly, but it's not runtime code, so
I'm a bit less concerned about that aspect.

This should take care of the problem mentioned in #1909

Paul Hinze 5d4e69cc80 helper/schema: apply schema defaults at the field level when reading from config

Mitchell Hashimoto 241fc5bb39 helper/schema: diff floats properly
/cc @phinze - This is pretty straightforward, almost magically so. The
reason this works is because in `diffString` we use mapstructure[1] with
"weak decode mode" to just be responisble for turning anything into a
string.

Emil Hessman 2bc612e6f8 helper/schema: fix panic when validating composite type
Don't check if the root key is being computed for composite types.
Instead, continue recursing the composite type in order to check if
the sub-key, key.N, for each individual element is being computed.

Fixes a panic which occurs when validating a composite type where
the value is an unknown kind for the schema.

Mitchell Hashimoto e5877543b2 helper/schema: track map element counts
This adds "field.#" values to the state/diff with the element count of a
map. This fixes a major issue around not knowing when child elements are
computed when doing variable access of a computed map.

Example, if you have a schema like this:

    "foo": &Schema{
        Type:     TypeMap,
        Computed: true,
    }

And you access it like this in a resource:

    ${type.name.foo.computed-field}

Then Terraform will error that "field foo could not be found on resource
type.name". By adding that "foo.#" is computed, Terraform core will pick
up that it WILL exist, so its okay.
