obsolete: add a high level function to create an obsolete marker

This function is designed to be used by all code that creates new
obsolete markers in the local repository.

It is not used by debugobsolete because debugobsolete allows the
use of an unknown hash as argument.

the parent of the ancestor node to be stripped does not become a head and
also, the parent of a node that is a child of the node stripped becomes a head
