Axel Dörfler f7bc46254a readwrite() was broken when it had to load more than one missing page at once.
It now prints a warning if the device driver doesn't handle iovecs correctly.
Again, this could lead to very strange behaviour.

Axel Dörfler 2ef444519e Work-around for buggy device drivers: some drivers (including our current
IDE drivers :-)) don't respect the total amount of bytes to be read in the
former readv() (now read_pages()) call. This can potentially fix all sorts
of strange errors in userland :)
Fixed the debug build.

Axel Dörfler d79751261c Added write support for the cache - it only writes internally right now,
it never writes back dirty pages. Code is not tested!

Axel Dörfler f72376a8dd The beginnings of a file cache. Read-only is already working fine; very
basic and with a temporary API.
