UserlandFS: Fix detection when a file system should be deleted.

This was a regression from hrev39870 where a private Referenceable class
was replaced with BReferenceable. Referenceable::RemoveReference()
returned a boolean to indicate whether the last reference was released
while BReferenceable::ReleaseReference() returns the previous reference
count.

A file system would therefore be deleted when any but the last reference
to it would be released (when multiple volumes of that file system were
mounted and one of them was unmounted) and leaked otherwise (when only
one volume of that file system was mounted and then unmounted).

Fixes #11718.

Replace uses of obsolescent BReference[able] API.

Removed left-over.

Removed the remnants of the dispatcher mechanism.

* Renamed UserlandFSServer to userlandfs_server. It is expected to live in
/system/servers, now.
* Got rid of the dispatcher application. It was the entity the kernel module
talked to when mounting a yet unknown FS. It started the client FS server
applications. Now the kernel module starts them directly. They use
respectively named ports, so the kernel module can find them when already
running.

Added a level of indirection in the FileSystem management
(FileSystemInitializer). This will allow for subclassing FileSystem
later.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20328 a95241bf-73f2-0310-859d-f6bbb57e9c96

Made the UserlandFS code gcc4 friendly.

First walk through the userlandfs kernel add-on to port it to the Haiku
FS interface. Adjusted old hooks, but didn't add the new ones yet. The
module builds now at least.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20235 a95241bf-73f2-0310-859d-f6bbb57e9c96

Copied userlandfs code from the test tree to the haiku source tree,
where it will be ported to Haiku.
