dirname-lgpl: adjust clients that don't need full dirname Some of these modules still use xalloc_die from other paths, but mkdir and rename are definitely reduced in complexity. * modules/backupfile (Depends-on): Use dirname-lgpl, not dirname. * modules/filenamecat (Depends-on): Likewise. * modules/linkat (Depends-on): Likewise. * modules/mkancesdirs (Depends-on): Likewise. * modules/mkdir (Depends-on): Likewise. * modules/openat (Depends-on): Likewise. * modules/savewd (Depends-on): Likewise. * modules/rename (Depends-on): Likewise. (License): Relax license. * modules/mkdir-tests (Depends-on): Drop progname. (Makefile.am): Delete unneeded LDADD. * modules/rename-tests (Depends-on, Makefile.am): Likewise.
