This is a clerical change that mostly changes http: to https: in URLs
where either will work. It also updates some URLs that have moved,
removes some URLs that no longer work, and fixes related text.

OpenBSD treats strerror_r(0,,) as a success, but with a message
"Undefined error: 0"; while this is distinct from strerror_r(-1,,)
returning "Unknown error: -1", it does not imply success. Meanwhile,
if buf is short enough for ERANGE, then we can't use strstr to look
for "Unknown" or "Undefined" in the resulting message, like we had
been doing for strerror(). Fix this by shifting the burden - now
the strerror-override code guarantees that 0 will have an
override when needed.

MacOS X 10.5 strerror(0) is "Unknown error: 0", which is not distinguished
from "Unknown error: -1" for out-of-range. Worse, strerror_r(0,,)
is "Undefined error: 0", although strerror_r for all other out-of-range
values matches strerror.

glibc was not the only platform where fprintf(fopen(,"r"))
fails to detect errors; cygwin 1.7.9 is another culprit
(although it will be fixed for 1.7.10), and I suspect that
several other platforms were failing perror2 for the same
reason.
At this point, there are so many functions affected, and
the way to avoid the bug is easy enough (don't pass bogus
streams to output-producing functions), that I'm not worried
about fixing things other than to document them.

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...

This uncovered a glibc bug, although not many people check for
perror failures, so for now I'm not working around it.
