Fix a few issues in the previous (disabled) HTTPS code,

and support linux as well (using fopencookie(), which should
be available in glibc).

Update configure.ac to check for funopen (BSD) and fopencookie(glibc),
and while we are at it also for gethostbyname_r
(the generated files need to be updated, or you need
to run bootstrap.sh yourself).

Document the new options in http.conf.sample
(names are only tentative, better ones are welcome).

At this point we can safely enable the option.
Anyone willing to try this on Sun and Apple platforms ?
