When a node number disagrees, keep track of all sources & the
node numbers they reported, and stick all that in the error message.
Changed all callers to supply a non-empty "source" argument; made
the "source" argument non-optional.
On my box, test_uuid still fails, but with the less confusing output:
AssertionError: different sources disagree on node:
from source 'getnode1', node was 00038a000015
from source 'getnode2', node was 00038a000015
from source 'ipconfig', node was 001111b2b7bf
Only the last one appears to be correct; e.g.,
C:\Code\python\PCbuild>getmac
Physical Address Transport Name

I can't find anything on my box with MAC 00-03-8a-00-00-15, and am
not clear on where that comes from.
