Automated rollback of commit 937350211dcd55a4714ec32ebbf33fffcc42cdf2.

*** Reason for rollback ***

Broke the go rules (of course)

See http://ci.bazel.io/job/rules_go/BAZEL_VERSION=HEAD,PLATFORM_NAME=linux-x86_64/1044/console.

*** Original change description ***

Resolve references to @main-repo//foo to //foo

Bazel was creating an dummy external repository for @main-repo, which
doesn't work with package paths and will cause conflicts once
@main-repo//foo and //foo refer to the same path.

This adds a "soft pull" option to WorkspaceNameFunction: it can either
parse the entire WORKSPACE file to find the name or just the first section.
That way PackageLookupFunction can find the repository name without causing
a circular dependency.

This should have no ch...
