HTTP: If-Modified-Since now allow clients from the future.

Before this patch the server did not respect a conditional
If-Modified-Since if the value was higher than the system server
date. This patch makes this pass, not a bug but make it more
friendly with Checker tools.

This patch also fix a QA script involved.

and when implementing the sendfile callback on some cases it will
need to re-call the routine until the Kernel enqueue the data.
