Move the runfiles for external repositories to under the x.runfiles/ directory

This also sets the Bazel workspace name to io_bazel_source.

Fixes #848.

Relevant to #1116, #1124,

RELNOTES[INC]: All repositories are now directly under the x.runfiles directory in the runfiles tree (previously, external repositories were at x.runfiles/main-repo/external/other-repo. This simplifies handling remote repository runfiles considerably, but will break existing references to external repository runfiles.
---
Furthermore, if a Bazel project does not provide a workspace name in the WORKSPACE file, Bazel will now default to using __main__ as the workspace name (instead of "", as previously). The repository's runfiles will appear under x.runfiles/__main__/.
