Added power management functions to support Dano (needed to boot Dano using

Browse Source 
our file system):
- added bfs_wake_vnode(), and bfs_suspend_vnode()
- bumped B_CUR_FS_API_VERSION to 3 as needed for Dano

It should now be able to boot Dano with our BFS, although I haven't tested
it. The information was gained using some degree of reverse engineering...
It won't be part of the BFS implementation for OpenBeOS (that won't run on R5
anymore) :-)
