many vfs improvements 
* There's no distinction between "temp" and "perm" nodes anymore.
    All nodes are allocated with 1 reference belonging to the
    vfs_alloc() caller.

    * VFSNode pointers retrieved by any API that returns one (most
    notably vfs_locate) are guaranteed to have exactly one reference
    belonging to the caller. What this means is that you must always
    decref them when you're done using them.

    If you're implementing such an API (e.g. a custom locate), remember
    to incref any persistent nodes you return.

    * Passing a VFSNode* to anything that successfully consumes one (for
    example, vfs_mount) transfers ownership of the reference to the
    consumer. In other words, consumers do not incref your nodes, but
    they will decref them once they don't need them anymore. If you want
    to keep the node around, then you must incref it first.

    * Bunch of other stuff.

"Ownership" is an abstract concept in this context. Basically it just
means "cleanup responsibility".
