dirname: split into dirname-lgpl dirname.h is proving quite useful from multiple LGPL modules, given the number of trailing slash bugs fixed in syscalls; only the calls to xalloc_die need to remain GPL. * modules/dirname-lgpl: New module. * modules/dirname (Files): Move library-safe files into dirname-lgpl. (Depends-on): Add dirname-lgpl. (configure.ac): Declare witness. * modules/double-slash-root (License): Relax license. * lib/dirname.h (base_name, dir_name): Only declare when using GPL module. * lib/dirname.c (dir_len, mdir_name): Move... * lib/dirname-lgpl.c: ...into new file. * lib/basename.c (last_component, base_len): Move... * lib/basename-lgpl.c: ...into new file. * m4/dirname.m4 (gl_DIRNAME_LGPL): New macro. (gl_DIRNAME): Use it. * MODULES.html.sh (Enhancements for POSIX:2008 functions): Mention new module. * modules/dirname-tests (Depends-on): Add progname. * tests/test-dirname.c (program_name): Delete.
