This patch introduces support for stacked file systems alongside new glue for accessing file-system implementations provided via Genode's new file-system-session interface. Using stacked file systems, an arbitrary number of file systems (such as tar archives or file systems implemented as separate Genode components) can be composed to form one merged virtual file system. An example is given via the 'ports/run/noux_bash.run' script. This run script creates a virtual file system out of multiple tar archives each containing the content of a particular GNU package. In addition, one 'ram_fs' is mounted, which enables Noux to perform write operations. This way, the shell output can be redirected to a file, or files can be saved in VIM. Fixes #103.
