José F. Romaniello c8795b8565 Add signum interpolation function
This function returns -1 for negative numbers, 0 for 0 and 1 for positive numbers.

Useful when you need to set a value for the first resource and a different value for the rest of the resources.

Example: `${element(split(",", var.r53_failover_policy), signum(count.index))}`

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.

Martin Atkins 0b85d35e87 Rename base64enc/dec to encode/decode.
There isn't any precedent for abbreviating words in the interpolation
function names, and it may not be clear to all users what "enc" and "dec"
are short for, so instead we'll prefer to spell out the whole words for
improved readability.

Paul Hinze e88aeede9b core: allow distinguishing between empty lists and strings
Had to handle a lot of implicit leaning on a few properties of the old
representation:

 * Old representation allowed plain strings to be treated as lists
   without problem (i.e. shoved into strings.Split), now strings need to
   be checked whether they are a list before they are treated as one
   (i.e. shoved into StringList(s).Slice()).
 * Tested behavior of 0 and 1 length lists in formatlist() was a side
   effect of the representation. Needs to be special cased now to
   maintain the behavior.
 * Found a pretty old context test failure that was wrong in several
   different ways. It's covered by TestContext2Apply_multiVar so I
   removed it.

Paul Hinze 7238b3b4af core: encapsulate representation of StringList
Now the only code that cares about how StringLists are represented lives
inside string_list.go

...which gives us the ability to change it! :)

Paul Hinze 10b3abf405 config: introduce StringList to abstract over list hack
This is the initial pure "all tests passing without a diff" stage. The
plan is to change the internal representation of StringList to include a
suffix delimiter, which will allow us to recognize empty and
single-element lists.

Paul Hinze b781c6c446 core: keys() and values() funcs for map variables
they work on maps with both keys and values that are string types, which
AFAICT are the only types of maps we have right now.

Josh Bleecher Snyder 02e751e356 config: add formatlist
formatlist distributes formatting over lists.
See the docs for details.

As a colleague commented:

"It happens all the time that we want a set of
outputs, but in a slightly different way than
just simple joining or concatting."

formatlist (combined with join)
makes it easy to satisfy those needs.
