Patches to allow running multiple vmware3 instances

[Per Hedeland]

Hi,

I just send-pr'ed some patches to allow running of multiple networked
vmware3 instances:

http://www.freebsd.org/cgi/query-pr.cgi?pr=68532

The scheme isn't very elegant, since it uses one vmnet interface per
vmware instance, but if your needs aren't very "dynamic", I think it's
OK. Only tested on 5.2.1-RELEASE, see the pr for some possible issues on
other versions (it should be possible to create the vmnet devices
manually on non-devfs systems - *before* running the start script...).
