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.

The files in here are mostly copyright (C) Free Software Foundation, and
are under assorted licenses.  Mostly, but not entirely, GPL.

Many modules are provided dual-license, either GPL or LGPL at your
option.  The headers of files in the lib directory (e.g., lib/error.c)
state GPL for convenience, since the bulk of current gnulib users are
GPL'd programs.  But the files in the modules directory (e.g.,
modules/error) state the true license of each file, and when you use
'gnulib-tool --lgpl --import <modules>', gnulib-tool either rewrites
the files to have an LGPL header as part of copying them from gnulib
to your project directory, or fails because the modules you requested
were not licensed under LGPL.

Some of the source files in lib/ have different licenses.  Also, the
copy of maintain.texi in doc/ has a verbatim-copying license, and
doc/standards.texi and make-stds.texi are GFDL.
