Revamp base system packaging of kernels to enable up/smp selection

at runtime and to support distributing additional kernels:
o remove kernel from the base tarball
o add new kernel tarballs
o build + package both SMP and GENERIC kernels when an <arch>/conf/SMP
  config file is present
o add sysinstall support for multiple kernels
o update sysinstall to probe for the number of cpus on a system
  and auto-select smp/up kernel accordingly
o add a post-kernels install hook to fixup /boot/kernel
o add -ldevinfo to boot crunch for sysinstall's cpu probing logic

Notes:
1. On HEAD this code is not currently used because GENERIC kernels
   include SMP.  This work is mainly intended for RELENG_6 where the
   GENERIC kernel is UP.  If HEAD changes to match then just enable
   WITH_SMP in sysinstall/Makefile.
2. The cpu probing support is done with acpi and MPTable; this means
   some systems will require work for auto-detection to work.
3. The handling of /boot/kernel may need to be revisited; for now
   we rename one kernel at the last moment (SMP if installed, otherwise
   GENERIC).  There are other, possibly better, approaches.

Lots of help from ru, emaste, scottl, and jhb.
