        src/lib/libkvm: Makefile kvm_i386.c

Added Files:
        src/lib/libkvm: kvm_i386pae.c

Log Message:
Import PAE support for kvm(3):
- add kvm_i386pae.c (used for PAE memory translations), and update Makefile
  for libkvm build.
- in pdppaddr: pass a flag to indicate PAE mode. Use a bit ignored
  by the MMU. Mask address with PG_FRAME to avoid side effects.

Tested with vmstat(1)/netstat(1) to debug core files of PAE and !PAE
kernels. Older kernel dumps will default to native i386 (!PAE) mode.

XXX Currently, savecore(8) will fail to dump a PAE kernel in a !PAE
    environment (and reciprocally). So you need to sync and reboot
    with a kernel of the same mode as the one that crashed. Once the dump
    is successful, this does not matter anymore.
