Only accept binary name not path

I think we've discussed this a couple of times, although I can't now
find a link.

There's really no reason to specify a path, it's complicated to
describe, and it might open up weird path traversal attacks,so
disallow it.

Rename setPayloadBinaryPath to setPayloadBinaryName to reflect this
(and rename lots of other things to match). Add a check that it isn't
a path, and a test for that (and fix some other tests that were
breaking the new rule).

Also expand on the Javadoc around ABI & 32/64-bit.

Also add a check inside VS (because checks in the payload code can be
bypassed), and a host test for that.

Note that a VM created with a config file can still specify a path
inside the config file; CompOS relies on that to run code from its
APEX.
