at this point we have no garantie that the header are sent
this can be ensured only at {WGI_RESPONSE}.commit exit.
Merge branch 'master' of https://github.com/EiffelWebFramework/EWF
Added assertion to WSF_UPLOADED_FILE
be sure we got the full content same as content length
check against capacity not count
Fixed MIME multipart form data handler
And use content-length value if provided.
Do not change tmp_name from WSF_UPLOADED_FILE ... otherwise the file will be removed at the end of the request
