kdbus: add node and filesystem implementation
kdbusfs is a filesystem that will expose a fresh kdbus domain context
each time it is mounted. Per mount point, there will be a 'control'
node, which can be used to create buses. fs.c contains the
implementation of that pseudo-fs. Exported inodes of 'file' type have
their i_fop set to either kdbus_handle_control_ops or
kdbus_handle_ep_ops, depending on their type. The actual dispatching
of file operations is done from handle.c
node.c is an implementation of a kdbus object that has an id and
children, organized in an R/B tree. The tree is used by the filesystem
code for lookup and iterator functions, and to deactivate children
once the parent is deactivated. Every inode exported by kdbusfs is
backed by a kdbus_node, hence it is embedded in struct kdbus_ep,
struct kdbus_bus and struct kdbus_domain.
