This PR also fixes/closes/invalidates #3639, with the logic implemented here you cannot repackage using the same name as the build_requires one, it raises with "ERROR: Loop detected: 'my_conanfile_base/1.0.23@lasote/testing' requires 'my_conanfile_base/1.0@lasote/testing' which is an ancestor too". Same if using requires instead of build_requires.

Previously behavior was different:

  • for build_requires both libraries were compiled, even if the build_Requires was already available
  • for requires it was entering an infinite loop.

Also, when this PR gets merged, we should revisit #3759 and #3822 (not sure if those will be open questions now).
