x86 vmm: add general multiprocessor support 

* repos/ports/include/vmm
 - add support to specify cpu location during vCPU construction
* seoul
 - update to latest seoul branch supporting smp
 - adjust to vmm interface changes
 - vCPUs will be put in a round robin fashion on the available host CPUs,
   beginning with the next CPU after the default (boot) CPU
 - number of vCPUs can be specified in run script
* virtualbox
 - adjust to vmm interface changes
 - uses still one vCPU, placed on default (boot) CPU

Fixes #1212
