progname: static check instead of dynamic * lib/progname.c: Don’t include stdio.h or stdlib.h. (set_program_name): Omit dynamic check that (with current glibc optimization) drags in fwrite even when unlocked I/O is wanted. The check was not all that useful in practice and we now have a static one anyway (which admittedly is not that useful either). Prefer memcmp to strncmp when equivalent, for clarity. * lib/progname.h: Include arg-nonnull.h and declare set_program_name with _GL_ARG_NONNULL. * modules/progname (Depends-on): Add snippet/arg-nonnull.
