* It is now supported that I/O operations and requests are only handled

partially (e.g. due to hitting the end of file). The respective
  classes have grown new methods and attributes to deal with that. The
  "finished" callbacks have got additional parameters to indicate
  whether the transfer was only partial and how much has been
  transferred. Other callbacks and functions have a size_t* in/out
  parameter instead of a simple size_t, now.
* vfs_{read,write}_pages() do now use the I/O request framework instead
  of the underlying FS's {read,write}_pages() hooks (those should be
  unused now). Furthermore they've got an additional "flags" parameter,
  which is passed to IORequest::Init(), i.e. it allows to specify that
  the given vecs refer to physical addresses.
* The file cache's read_into_cache() reads directly into physical
  pages, now.
* Fixed bug in DoIO::IO(): The offset was not adjusted, so that all
  pages were incorrectly transferred from/to the same location.
* Fixed broken subrequest scheduling loop head in
  do_iterative_fd_io_iterate().
* Adjusted the test driver and implemented its io() hook. Using this
  driver I/O requests are passed all the way from the VFS/VM to the
  driver and through the I/O scheduler. It even seems to work. :-)
* Added missing const to the iovec* parameter of the IORequest::Init()
  methods.
* Disabled some debug output by default. Added new optional debug
  output.
