This overload of the value member eases the retrieval of Genode::String
objects from XML attributes. So we won't need to deal with C-style
character buffers anymore.
By appending a newline to the generated XML data, we prevent the output
from messing with the command prompt when using 'cat' on a shell.
Futhermore, when using line-buffered output, the trailing newline
ensures that the output gets gets properly flushed.
When calling 'sub_node' on a node with no sub nodes, the Xml_node would
interpret the characters after the current node while searching for sub
nodes. The patch adds a sanity check that lets the 'sub_node' function
throw an exception when called on a node with no sub nodes.
This patch makes the handling of constructor arguments consistent among
the Volatile_object and Lazy_volatile_object classes. Arguments are
always forwarded. Otherwise, passing a reference as argument would result
in an unwanted copy of the passed object.
This patch changes the top-level directory layout as a preparatory
step for improving the tools for managing 3rd-party source codes.
The rationale is described in the issue referenced below.
