Handle changing host address better

Detailed description
When using VMs, the host and target address are both important.  When the target address is wrong, it's obvious something
is wrong (since the dialogs show this address).  But when the host address is wrong, you can only tell this in the warning
page in the Build Machines setup.  A wrong address will cause shared folder mounting to fail (or existing shares to
fail) but this is not detected or reported anywhere else.

Probably this should be fixed in two ways: 

(1) Validate the host address in more places.  Ping the host from the VM to validate it.

(2) Allow the Machine Setup pane to use a floating host address (e.g. "<auto>").  Generally you want
the host address on the same subnet as the target address, unless the target address is for NAT.  We might be able to
guess this in most cases.

I fixed this using option (1) during the validate machines operation
in rev 2371.

Also, a recommendation that is more flexible in general is to
simply use a hostname (not an IP) in the "local address"
field.  This way, the setting is less prone to DHCP changes.
With a few fixes with regard to address equality checks, this
has worked for me for a few weeks over several DHCP changes.
