Axel Dörfler eb9f0103f8 file_cache_delete() can now safely be used with a NULL pointer.

Axel Dörfler e4211d820c Fixed another bad bug in the file cache: when one iovec would have to be 
divided into several parts, it could happen that overwrite the whole data
portion with data beyond the part that should have been read.

Axel Dörfler 7605ddddf0 Replaced all remaining PAGE_SIZE with B_PAGE_SIZE and "addr" with addr_t.

Axel Dörfler 57bf060563 Fixed another stupid bug in the file cache: when the first read was a partial 
read over two blocks, some memory behind that memory could be trashed.

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.
