eliminate the PMAP_NEW option by making it required for all ports.
...
ports which previously had no support for PMAP_NEW now implement
the pmap_k* interfaces as wrappers around the non-k versions.

Move the user-set LDT out of the PCB and into the pmap. Applications
...
which set the LDT and share VM space (e.g. new versions of WINE) expect
the LDT to be logically coupled to the address space. Use the new pmap_fork()
interface to copy non-shared user-set LDTs when the address space is forked.
