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.

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

55efd37df7 Added the file_cache.cpp file to the build. 
_KERNEL_MODE is already defined when using kernel build rules, no need
to do it here manually.

e02c12f0b3 Added a "cookie" parameter to the vfs_read|write|has_page[s]().

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

7f2ba8be02 Now clears out any remainders of the pages in the iovecs if the request 
couldn't be satisfied completely (ie. because the file size is not a
multiple of the page size).
It's no longer necessary to implement this functionality in the file systems.

26de720c84 The VM store interface has changed to better match the one of the device interface.

447a16653a Added a basic vnode store, more or less the same as the old one.

125f4d5101 Implemented a "block map" that can efficiently map contiguous blocks to 
addresses.
Not yet used - might be used instead of the vm_cache page caching for the file cache.

6a3016d2ab Moved the block cache to this file (from ../vm/cache.cpp). 
It still contains a very dump version of a BeOS compatible block cache.
