Message:

Merge from lp:~jakub/helenos/fs.

Highlights of the merge:

• the kernel signs each call by the sender's task hash

• async framework tracks and reference counts connections from the same client task

• VFS associates the table of open files with the client task rather than with a single connection

• VFS libc client code now uses async sessions to support parallel requests

• vfs_file_get() now explicitly adds a reference on the file structure and the newly introduced vfs_file_put() drops it
