IOS: Add partial wfsi/wfssrv implementations. 

The current implementations do many things wrong but work well enough to
run the Dragon Quest X installer until the very end. The game itself
crashes when being launched from its System Menu channel unfortunately
so it is hard to verify whether the install properly worked or not.

There are plenty of "TODO(wfs)" sprinkled around this codebase with
things that are knowingly done wrong. The most important one right now
is that content extraction is done by buffering everything into memory
instead of properly streaming the data to disk (and processing
asynchronously), which causes freezes. It is likely to not cause any
practical issues since only the installer and the updater should use
this anyway.
