Creates a new package called clientcredentials and adds transport and token information to the internal package. Also modifies the oauth2 package to make use of the newly added files in the internal package. The clientcredentials package allows for token requests using a "client credentials" grant type. Fixes https://github.com/golang/oauth2/issues/7 Change-Id: Iec649d1029870c27a2d1023baa9d52db42ff45e8 Reviewed-on: https://go-review.googlesource.com/2983 Reviewed-by: Burcu Dogan <jbd@google.com> Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>
