Node: Keep track of VFS init status

* Node::VFSInit() and VFSUninit() set/clear the new node flag
NODE_FLAG_KNOWN_TO_VFS. They need to be called by overriding methods,
now.
* Add Node::IsKnownToVFS() which returns the VFS init status.

Implement more virtuals in Node and Directory

* Node: Add default implementations for UserID(), GroupID(),
OpenAttributeDirectory(), and OpenAttribute().
* Directory: Add default implementations for Mode() and FileSize().
* Remove the respective hook implementations in the PackageLink*
classes.

Attribute index support for non-special attributes

* Add AttributeIndex class.
* Each attribute does now have an attribute index cookie. The new
attribute index service methods Node::IndexAttribute() and
IndexCookieForAttribute() create+set/retrieve the cookie. The cookie
is actually the attribute index's tree node.
* Add OldNodeAttribute::IndexCookieForAttribute() so the cookie is
available when the node changes.

Add Node::Init() flags parameter

* Add Node::Init() flags:
- NODE_FLAG_KEEP_NAME: Take over ownership of the name.
- NODE_FLAG_CONST_NAME: Don't copy the name -- it's a constant that
lives at least as long as the object.
* Remove Init() implementations in derived classes that just call the
base class version.

Empty Node::VFS{Init(),Uninit}() implementations

Node: Add setters for ID and parent

Remove unused Node fields

Work in progress:
* The FS parses package files from "/boot/common/packages" and builds an
node tree representation of the contained entries. Merging directories should
work. Lots of other stuff is missing yet, though.
* Implemented the hooks for directory entry lookup and iteration. So it's
possible to see the contents of the FS at least.

Implemented the most basic functionality required to cleanly mount and unmount
(at least in userlandfs).
