Log Message:
Rudimentary support for LFS under UBC:

- LFS-specific VOP_BALLOC and VOP_PUTPAGES vnode ops.

- getblk VREG panic #ifdef'd out (can be reinstated when Ifile is
  internalized and Ifile can be made another type from VREG)

- interface to VOP_PUTPAGES changed to pass all pager flags, not
  just sync.  FS putpages routines must know about the pager flags.

- new LFS magic disk address, -2 ("unwritten"), meaning accounted for
  but not assigned to a fixed disk location (since LFS does these two
  things separately, and the previous accounting method using buffer
  headers no longer will work).  Changed references to (foo == (daddr_t)-1)
  to (foo < 0).  Since disk drivers reject all addresses < 0, this should
  not present a problem for other FSs.
