Refactored how files, directories and stdin are handled. Every file must pass
through the FileVisitor and then streamed through StreamVisitor. FileVisitor
takes care of opening/closing files and StreamVisitor is parsing multiple
resources.
In resource.Builder ContinueOnError() should actually do so.
Reorganized util.CheckErr() to make it display bulk errors more
effectively and be more reusable. Clarified that CheckErr is not
specific to kubectl in Godoc. Changed the "Error: " prefix to
"error: " to more closely match Unix conventions.
Make clients opt in to decoding objects that are stored
in the generic api.List object by invoking runtime.DecodeList()
with a set of schemes. Makes it easier to handle unknown
schema objects because decoding is in the control of the code.
Add runtime.Unstructured, which is a simple in memory
representation of an external object.
Will allow xarg behavior to fetch resources across multiple types.
Changes 'create', 'get', 'update', 'stop', and 'delete' to output
<resourceType>/<name>.
Create a unified Builder object for working with files, selectors,
types, and items that makes it easier to get multi-object functionality.
Supports all of the behaviors previously in resource.go, but with
additional flexibility to allow multi-type retrieval and access, directories,
URLs, nested objects, and lists.
