- Add a SPDX header;
- Adjust document and section titles;
- Some whitespace fixes and new line breaks;
- Mark literal blocks as such;
- Add table markups;
- Add it to filesystems/index.rst.

+What is this Driver?
+====================
+This module implements the native filesystem of BeOS http://www.beincorporated.com/

+=========================
+Be, Inc said, "BeOS Filesystem is officially called BFS, not BeFS".
 But Unixware Boot Filesystem is called bfs, too. And they are already in
 the kernel. Because of this naming conflict, on Linux the BeOS
 filesystem is called befs.
