James Nugent 3bdd1ac8b3 core: Display invalid type in error message
If a variable type which is invalid (e.g. "stringg") is declared, we now
include the invalid type description in the error message to make it
easier to track down the source of the error in the source file.

James Nugent cb6cb8b96a core: Support explicit variable type declaration
This commit adds support for declaring variable types in Terraform
configuration. Historically, the type has been inferred from the default
value, defaulting to string if no default was supplied. This has caused
users to devise workarounds if they wanted to declare a map but provide
values from a .tfvars file (for example).

The new syntax adds the "type" key to variable blocks:

```
variable "i_am_a_string" {
    type = "string"
}

variable "i_am_a_map" {
    type = "map"
}
```

This commit does _not_ extend the type system to include bools, integers
or floats - the only two types available are maps and strings.

Validation is performed if a default value is provided in order to
ensure that the default value type matches the declared type.

In the case that a type is not declared, the old logic is used for
determining the type. This allows backwards compatiblity with previous
Terraform configuration.

Paul Hinze 0739cf2348 provider/template: fix race causing panic in template_file
The render code path in `template_file` was doing unsynchronized access
to a shared mapping of functions in `config.Func`.

This caused a race condition that was most often triggered when a
`template_file` had a `count` of more than one, and expressed itself as
a panic in the plugin followed by a cascade of "unexpected EOF" errors
through the plugin system.

Here, we simply turn the FuncMap from shared state into a generated
value, which avoids the race. We do more re-initialization of the data
structure, but the performance implications are minimal, and we can
always revisit with a perf pass later now that the race is fixed.

Paul Hinze 15e7927009 config: test covering escaped quotes syntax error
This was never intended to be valid syntax, but it worked in the old HCL
parser, and we've found a decent number of examples of it in the wild.

Fixed in https://github.com/hashicorp/hcl/pull/62 and we'll keep this
test in Terraform to cover the behavior.

Paul Hinze 928f534cfc template_file: source contents instead of path
Building on the work of #3846, deprecate `filename` in favor of a
`template` attribute that accepts file contents instead of a path.

Required a bit of work in the interpolation code to prevent Terraform
from assuming that template interpolations were resource variables that
needed to be resolved. Leaving them as "Unknown Variables" prevents
interpolation from happening early and lets the `template_file` resource
do its thing.

James Nugent f4164b5322 Add resource with heredoc to config load tests
This test reproduces the issue which is likely the root cause of #3840.
Test is currently failing with an "illegal character" message
corresponding with the location of the heredoc, which is also seen in
various acceptance tests for providers.

It has improvements to error messaging that we want.

We'll use this occasion begin developing / building with Go 1.5 from
here on out. Build times will be slower, but we have core development
plans that will help mitigate that.

Martin Atkins ef161e1c1b Various interpolation functions for CIDR range manipulation.
These new functions allow Terraform to be used for network address space
planning tasks, and make it easier to produce reusable modules that
contain or depend on network infrastructure.

For example:
- cidrsubnet allows an aws_subnet to derive its
  CIDR prefix from its parent aws_vpc.
- cidrhost allows a fixed IP address for a resource to be assigned within
  an address range defined elsewhere.
- cidrnetmask provides the dotted-decimal form of a prefix length that is
  accepted by some systems such as routing tables and static network
  interface configuration files.

The bulk of the work here is done by an external library I authored called
go-cidr. It is MIT licensed and was implemented primarily for the purpose
of using it within Terraform. It has its own unit tests and so the unit
tests within this change focus on simple success cases and on the correct
handling of the various error cases.
