Paul Hinze 434a9759a0 providers/aws: enhance root_block_device acceptance test
So that we have a test that will fail in case the flubbery of #1000
returns.

Paul Hinze 73d20b4c58 providers/aws: add root_block_device to aws_instance
AWS provides a single `BlockDeviceMapping` to manage three different
kinds of block devices:

 (a) The root volume
 (b) Ephemeral storage
 (c) Additional EBS volumes

Each of these types has slightly different semantics [1].

(a) The root volume is defined by the AMI; it can only be customized
with `volume_size`, `volume_type`, and `delete_on_termination`.

(b) Ephemeral storage is made available based on instance type [2]. It's
attached automatically if _no_ block device mappings are specified, and
must otherwise be defined with block device mapping entries that contain
only DeviceName set to a device like "/dev/sdX" and VirtualName set to
"ephemeralN".

(c) Additional EBS volumes are controlled by mappings that omit
`virtual_name` and can specify `volume_size`, `volume_type`,
`delete_on_termination`, `snapshot_id`, and `encryption`.

After deciding to ignore root block devices to fix #859, we had users
with configurations that were attempting to manage the root block device chime
in on #913.

Terraform does not have the primitives to be able to properly handle a
single collection of resources that is partially managed and partially
computed, so our strategy here is to break out logical sub-resources for
Terraform and hide the BlockDeviceMapping inside the provider
implementation.

Now (a) is supported by the `root_block_device` sub-resource, and (b)
and (c) are still both merged together under `block_device`, though I
have yet to see ephemeral block devices working properly.

Looking into possibly separating out `ephemeral_block_device` and
`ebs_block_device` sub-resources as well, which seem like the logical
next step. We'll wait until the next big release for this, though, since
it will break backcompat.

Paul Hinze 219aa3e788 helper/schema: fix DiffFieldReader map handling
An `InstanceDiff` will include `ResourceAttrDiff` entries for the
"length" / `#` field of maps. This makes sense, since for something like
`terraform plan` it's useful to see when counts are changing.

The `DiffFieldReader` was not taking these entries into account when
reading maps out, and was therefore incorrectly returning maps that
included an extra `'#'` field, which was causing all sorts of havoc
for providers (extra tags on AWS instances, broken google compute
instance launch, possibly others).

 * fixes #914 - extra tags on AWS instances
 * fixes #883 - general core issue sprouted from #757
 * removes the hack+TODO from #757

Paul Hinze c88c4a33e1 providers/aws: ignore ec2 root devices
fixes #859

EC2 root block devices are attached automatically at launch [1] and show
up in DescribeInstances responses from then on. By skipping these when
recording state, Terraform can avoid thinking there should be block
device changes when there are none.

Note this requires that https://github.com/mitchellh/goamz/pull/214 land
first so the proper field is exposed.
