test/common.py: fix race condition waiting for the helper connection

The wait_for_connections() method, which is used at the start of
test_system to make sure that all the clients are connected to all the
servers, did not also wait for clients to be connected to their Helpers.
Every once in a while, the helper connection would take a bit longer,
and then
test_system.SystemTest.test_filesystem._test_web._got_welcome_helper
would fail, because we'd check for a helper connection before it was
ready.

The fix is to modify wait_for_connections's polling predicate to look
for helper connections (if configured) as well as the regular
introducer- and server- connections.

Tested by temporarily adding a large (30s) delay to the connectTo() call
in Uploader.startService, simulating a long helper
connection-establishment delay. This makes the test fail consistently.
Then I fixed wait_for_connections(), and the test passed (slowly). Then
I removed the delay.

Improve the column headers to make it clear that this list shows Tub

those to us: only servers provide pubkeys). This should be the only

test_system.py: clean up control flow, reduce use of stall()

The _upload_resumable() test interrupts a Helper upload partway

resumes the upload. The control flow is kind of tricky: to do anything

client.py: rename "server key" to "node key", use old name if present

This prepares for invitation-based reciprocal-permission Accounting. In
the scheme I'm developing, nodes publish "I accept shares from Y"
messages, which are assembled into a graph, and server will accept
shares from any client node reachable in this graph. For this to work,
the serverX->clientY edge must be connectable to the serverY->clientZ
edge, which means "clientY" and "serverY" must be connected. If clientY
and serverY are two distinct keys, they must be cross-signed. Life is
easier if there's just one key "Y", rather than distinct client- and
server- keys. Calling this one key "server.privkey" would be confusing.
"node.privkey" and "node.pubkey" makes more sense.

One-server-per-node is a pretty easy restriction. Originally I was
thinking that the client.key should be provided in each webapi call,
just like a filecap is, making a single node useable by multiple users
(Accounting principals), and not providing any ambient storage
authority. But I've been unable to think of a comfortable WUI for
that (at least without requiring javascript), nor a friendly way to
transfer account authority (e.g. writecaps that include storage
authority). So I'm more willing to have one-client-per-node these days.

(and note that this rename doesn't seriously preclude
many-clients-per-node or zero-clients-per-node anyways, it just makes
one-client-per-node less awkward)

for ciphertext. The "Contacting Helper" report includes both
existence_check and the client-helper RTT.

For non-overlapping uploads, it was being returned correctly. But when
multiple upload requests overlapped, and the file was not already in the
grid, the filecheck would only run once, and its existence_check time
would be reported for all uploaders (even if they didn't have to wait
for that time). Cleaning that up proved too difficult: the only correct
place to report this time is from the initial remote_upload_chk() call,
but the return value of that is too constrained to accomodate it in the
needs-upload case.

So I'm removing it altogether. Eventually I plan to add a proper
events/times field and record more data, including this check, in a form
that can be drawn on a nice zoomable timeline view.

Old clients talking to a new Helper (which doesn't supply the value)

immutable repairer: populate servers-responding properly

RepairResults.data["servers-responding"] list. (This resulted from a
buggy usage of DictOfSets.union() in filenode.py).

In addition, servers to which filecheck queries were sent, but did not
respond, were incorrectly added to the servers-responding list
anyawys. (This resulted from code in the checker.py not paying attention
to the 'responded' flag).

The first bug was neatly masked by the second: it's pretty rare to have
a server suddenly start responding in the one-second window between a
filecheck and a subsequent repair, and if the server was around for the
filecheck, you'd never notice the problem. I only spotted the smelly

incorrectly asserting that 10 servers responded, when in fact one of
