vbox: workaround for bug in Windows guest addition

In file

src/VBox/Additions/WINNT/SharedFolders/driver/file.c

the function

static int vbsfTransferCommon(VBSFTRANSFERCTX *pCtx)

in the

VbglR0CanUsePhysPageList()

branch does not correctly evaluate the read or written bytes from
the VMM. It ever assumes that whole pages are read/written.

Workaround the bug in the Windows guest additions of Vbox until fixed
upstream by filling up the read/write buffer completely within the VMM code
of Vbox.

loader: allow to set the parent of the subsystem's view

This commit adds a 'parent_view()' function to the loader session, which
allows to set the parent view of the subsystem's Nitpicker view.

If the function is to be used, this must get done before calling
'start()'.

Fixes #1172.

as reference or pointer.
