priv-set: new module and accompanying tests; adapt write-any-file * lib/priv-set.c: New file. * lib/priv-set.h: New file. * lib/unlinkdir.c: Make cannot_unlink_dir thread-safe. * lib/write-any-file.c: Simplify by using priv-set module. * m4/priv-set.m4: New file. * modules/priv-set: New file. * modules/unlinkdir: Add dependency on priv-set module. * modules/write-any-file: Likewise. These changes address a problem that originally arose with GNU tar: http://thread.gmane.org/gmane.comp.gnu.tar.bugs/3242 Tests for module 'priv-set'. * modules/priv-set-tests: New file.
