usleep: new module mingw usleep(1000000) failed with EINVAL, as allowed by POSIX, but contrary to GNU usage. Rather than implement an accurate usleep based on select or nanosleep, both of which drag in dependencies on external libraries, this version intentionally takes the ceiling in seconds if usleep() is missing. * modules/usleep: New file. * m4/usleep.m4 (gl_FUNC_USLEEP): Likewise. * lib/usleep.c (usleep): Likewise. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Add defaults. * modules/unistd (Makefile.am): Substitute witnesses. * lib/unistd.in.h (usleep): Add declaration. * doc/pastposix-functions/usleep.texi (usleep): Document this. * MODULES.html.sh (Date and time): Likewise. * modules/usleep-tests (Depends-on): New test. * tests/test-usleep.c: New file.
