Move vnode-to-file-handle translation from vfs_vptofh to vop_vptofh

This way we may support multiple structures in v_data vnode field within
one file system without using black magic.
Vnode-to-file-handle should be VOP in the first place, but was made VFS
operation to keep interface as compatible as possible with SUN's VFS.
BTW. Now Solaris also implements vnode-to-file-handle as VOP operation.
VFS_VPTOFH() was left for API backward compatibility, but is marked for
removal before 8.0-RELEASE.
Approved by: mckusick
Discussed with: many (on IRC)
Tested with: ufs, msdosfs, cd9660, nullfs and zfs
Do you think API backward compatibility is actually required in 7.x? It
looks like you've updated all the file systems, in which case the temptation
would be to drop it as we already have other VFS changes in 7.x from 6.x.
Also, you probably need to do something about the VFS_FHTOVP(9) man page for
completeness.
