Previously, libraries were loaded by instance_eval'ing them against
the same execution context used for control files. All resources were
registered against a single global registry when the `name` dsl method
was invoked. To obtain seperation of resources, we would mutate the
instance variable holding the globale registry and then change it back
at the end.
Now, we instance_eval library files inside an anonymous class. This
class has its own version of `Inspec.resource` that returns another
class with the resource DSL method and the profile-specific resource
registry.
The goal of these changes is to ensure that the libraries from
dependencies are loaded even if their controls are never included. To
facilitate this, we break up the loading into seperate steps, and move
the loading code into the Profile which has acceess to the dependency
information.

Previously, all resources were loaded into a single resource registry.
Now, each profile context has a resource registry, when a profile's
library is loaded into the profile context, we update the
profile-context-specific resource registry. This local registry is
then used to populate the execution context that the rules are
evaluated in.

A few minor issues were causing 3 functional test failures on OS X.
These were not program errors but where rather the result of the
profiles under test assuming a linux environment.
Since many of the developers who will work on this project in the future
will be running OS X, let's ensure they can run the functional tests
easily.

The goal of this change is to provide an isolated view of the available
profiles when the user calls the include_controls or require_controls
APIs. Namely,
- A profile should only be able to reference profiles that are part of
its transitive dependency tree. That is, if the dependency tree for a
profile looks like the following:
A
|- B --> C
|
|- D --> E
Then profile B should only be able to see profile C and fail if it
tries to reference A, D, or E.
- The same profile should be include-able at different versions from
different parts of the tree without conflict. That is, if the
dependency tree for a profile looks like the following:
A
|- B --> C@1.0
|
|- D --> C@2.0
Then profile B should see the 1.0 version of C and profile D should
see the 2.0 profile C with respect to the included controls.
To achieve these goals we:
- Ensure that we construct ProfileContext objects with respect to the
correct dependencies in Inspec::DSL.
- Provide a method of accessing all transitively defined rules on a
ProfileContext without pushing all of the rules onto the same global
namespace.
This does not yet handle attributes or libraries.
This extends the dependency feature to include support for url-based
dependencies. It takes some deviations from the current support for
URLs that we'll likely want to make more consistent.
By default, we store downloaded archives in the cache rather than the
unpacked archive. However, to facilitate debugging, we will prefer the
unpacked archive if we find it in the cache.
