perror: adjust array size
...
If we ever adjust strerror-override.h to have a larger size for
STACKBUF_LEN, then perror should also pick up the adjustment.
* modules/perror (Depends-on): Add strerror-override.
* lib/perror.c (perror): Use it to avoid magic number.

perror: call strerror_r directly
...
No need to make a wrapper that burns static storage when we can
just use stack storage.
* modules/perror (Files): Drop strerror-impl.h.
* lib/perror.c (perror): Use our own stack buffer, rather than
calling a wrapper that uses static storage.
* doc/posix-functions/perror.texi (perror): Document a limitation
of our replacement.

perror: work around FreeBSD bug
...
POSIX requires that 'errno = 0; perror ("")' print the same message
as strerror(0), but this failed if we were replacing strerror to work
around the FreeBSD bug of treating 0 as a failure.
The goal here is to _not_ replace perror on glibc, even though
strerror_r has to be replaced, because the strerror_r replacement is
only for the sake of correcting the signature rather than working
around bugs in the handling of any particular errnum value. Recall
that $gl_cv_func_strerror_r_works is only set if the POSIX signature
was detected in the first place.
* m4/perror.m4 (gl_FUNC_PERROR): Also replace perror if strerror_r
is broken. Move AC_LIBOBJ...
* modules/perror (configure.ac): Here.
* doc/posix-functions/perror.texi (perror): Document this.
* tests/test-perror2.c (main): Enhance test.
