getcwd-lgpl: new module
For programs that aren't worried about being invoked from an
current working directory longer than PATH_MAX (perhaps because
the program always does chdir to a sane location first), the
getcwd module is overkill, given that all modern portability
targets have a getcwd that works on short names.
* modules/getcwd-lgpl: New module.
* lib/getcwd-lgpl.c: New file.
* doc/posix-functions/getcwd.texi (getcwd): Document it.
* MODULES.html.sh (lacking POSIX:2008): Likewise.
* modules/getcwd (configure.ac): Set C witness.
* m4/getcwd.m4 (gl_FUNC_GETCWD_LGPL): New macro.
