Subject: [PATCH 07/14] Add virFileMakeParentPath helper function

Add a helper function which takes a file path and ensures
that all directory components leading up to the file exist.
IOW, it strips the filename part of the path and passes
the result to virFileMakePath.

(cherry picked from commit c321bfc5c37c603af349dacf531bb03c91b0755e)
