This is a new module, providing a <sys/wait.h> file that also (more or less)
works on native Windows (mingw).

New module 'sys_wait'.
* modules/sys_wait: New file.
* lib/sys_wait.in.h: New file, partially copied from
lib/wait-process.c.
* m4/sys_wait_h.m4: New file.
* doc/posix-headers/sys_wait.texi: Mention the new module.
