Still there is an issue with re-open a file. Patch applied below to

avoid it.

Also iterate_post() always returns MHD_OK, because the app's logic
driven
from the value of con_info->answercode().
And in case if fwrite() fails we also update the answer code & page  and
MHD_post_process() overwrite them (fileioerror becomes postprocerror).
