5bae4a1bd2 Mutable repair: use new MODE_REPAIR to query all servers *and* get privkey 
This fixes bug #1689. Repair was using MODE_READ to build the servermap,
which doesn't try hard enough to grab the privkey, and also doesn't guarantee
sending queries to all servers. This patch adds a new MODE_REPAIR which does
both, and does a separate, distinct mapupdate to start wth repair cycle,
instead of relying upon the (MODE_CHECK) mapupdate leftover from the
filecheck that triggered the repair.

a56e639346 Fix mutable status (mapupdate/retrieve/publish) to use serverids, not tubids 
This still leaves immutable-publish results incorrectly using tubids instead
of serverids. That will need some more work, since it might change the Helper
interface.

1469b1b9f9 Ensure that verification proceeds and stops when appropriate. 
The removed assertions are appropriate for a download that seeks to
return plaintext to a caller; if we don't have at least k active remote
shares, then we can't hope to do that. They're not appropriate for a
verification operation; a user can try to verify a file that has fewer
than k shares available, so that shouldn't be treated as an error.
Instead, we proceed with fewer than k shares, and ensure that we
terminate the download if we have no shares at all and we're verifying.

893eea849b mutable/retrieve.py: clean up control flow to avoid dropping errors 
* replace DeferredList with gatherResults, simplify result handling
* use BadShareError to signal recoverable problems in either fetch or
  validate, catch after _validate_block
* _validate_block is thus not responsible for noticing fetch problems
* rename _validation_or_decoding_failed() to _handle_bad_share()
* _get_needed_hashes() returns two Deferreds, instead of a hard-to-unpack

e29323f68f mutable publish: track multiple servers-per-share. Fixes some of #1628. 
The remaining work is to write additional tests.

src/allmydata/test/no_network.py:

 This supports tests in which servers leave the grid only to return with
 their shares intact at a later time.

src/allmydata/test/test_mutable.py:

 The UCWEs in the incident reports associated with #1628 all seem to be
 associated with shares that the servermap knows about, but which aren't
 accounted for during the publish process for whatever reason. Specifically,
 it looks like the publisher is only capable of keeping track of a single
 storage server for a given share. This makes the repair process worse than
 it was pre-MDMF at updating all of the shares of a particular file to the
 newest version, and can also cause spurious UCWEs. This test simulates such
 a layout and fails if an UCWE is thrown. We need to write another test to
 ensure that all copies of a share are updated to the latest version (or
 alter this test to do that), so that the test suite doesn't pass unless both
 regressions are fixed.

 We want the publisher to follow the existing share placement when uploading
 a new version of a mutable file, and we don't want this test to pass unless
 it does.

src/allmydata/mutable/publish.py:

 Before this commit, the publisher only kept track of a single writer for
 each share. This is insufficient to handle updates in which a single share
 may live on multiple servers. In the best case, an update will only update
 one of the existing shares instead of all of them. In some cases, the update
 will encounter the existing shares when publishing some other share,
 interpret it as a sign of an uncoordinated update, and fail. Keeping track
 of all of the writers helps ensure that all existing shares are updated, and
 helps avoid spurious uncoordinated write errors.

5bf1ffbc87 IServer refactoring: pass IServer instances around, instead of peerids 
refs #1363

This collapses 88 small incremental changes (each of which passes all tests)
into one big patch. The development process for the long path started with
adding some temporary scaffolding, changing one method at a time, then
removing the scaffolding. The individual pieces are as follows, in reverse
chronological order (the first patch is at the end of this comment):

633641174a mutable/retrieve: don't write() after we've been pauseProducer'ed 
This fixes a test failure found against current Twisted trunk in
test_mutable.Filenode.test_retrieve_producer_mdmf (when it uses
PausingAndStoppingConsumer). There must be some sort of race: I could
make it fail against Twisted-11.0 if I just increased the 0.5s delay in
test_download.PausingAndStoppingConsumer to about 0.6s, and could make
Twisted-trunk pass by reducing it to about 0.3s .

I fixed the test (as opposed to the bug) by replacing the delay with a
simple reliable eventually(), and adding extra asserts to fail the test
if the consumer's write() method is called while the producer is
supposed to be paused

The bug itself was that mutable.retrieve.Retrieve wasn't checking the
"stopped" flag after resuming from a pause, and thus delivered one
segment to a consumer that wasn't expecting it. I split out
stopped-flag-checking to separate function, which is now called
immediately after _check_for_paused(). I also cleaned up some Deferred
usage and whitespace.

0716c496c8 MDMF: remove extension fields from caps, tolerate arbitrary ones. Fixes #1526 
The filecaps used to be produced with hints for 'k' and segsize, but they
weren't actually used, and doing so had the potential to limit how we change
those filecaps in the future. Also the parsing code had some problems dealing
with other numbers of extensions. Removing the existing fields and making the
parser tolerate (and ignore) extra ones makes MDMF more future-proof.

2edfb1a334 Retrieve: remove the initial prefix-is-still-good check 
This check needs to be done with each fetch from the storage server, to
detect when someone has changed the share (i.e. our servermap goes stale).
Doing it just once at the beginning of retrieve isn't enough: a write might
occur after the first segment but before the second, etc.

_try_to_validate_prefix() was not removed: it will be used by the future
check-with-each-fetch code.

test_mutable.Roundtrip.test_corrupt_all_seqnum_late was disabled, since it
fails until this check is brought back. (the corruption it applies only
touches the prefix, not the block data, so the check-less retrieve actually
tolerates it). Don't forget to re-enable it once the check is brought back.

9756146d61 Fix mutable publish/retrieve timing status displays. Fixes #1505. 
publish:
* encrypt and encode times are cumulative, not just current-segment

retrieve:
* same for decrypt and decode times
* update "current status" to include segment number
* set status to Finished/Failed when download is complete
* set progress to 1.0 when complete

More improvements to consider:
* progress is currently 0% or 100%: should calculate how many segments are
  involved (remembering retrieve can be less than the whole file) and set it
  to a fraction
* "fetch" time is fuzzy: what we want is to know how much of the delay is not
  our own fault, but since we do decode/decrypt work while waiting for more
  shares, it's not straightforward

0f1d674d76 MutableFileNode.set_downloader_hints: never depend upon order of dict.values() 
The old code was calculating the "extension parameters" (a list) from the
downloader hints (a dictionary) with hints.values(), which is not stable, and
would result in corrupted filecaps (with the 'k' and 'segsize' hints
occasionally swapped). The new code always uses [k,segsize].

370e6f271e SDMF: update filenode with correct k/N after Retrieve. Fixes #1510. 
Without this, we get a regression when modifying a mutable file that was
created with more shares (larger N) than our current tahoe.cfg . The
modification attempt creates new versions of the (0,1,..,newN-1) shares, but
leaves the old versions of the (newN,..,oldN-1) shares alone (and throws a
assertion error in SDMFSlotWriteProxy.finish_publishing in the process).

The mixed versions that result (some shares with e.g. N=10, some with N=20,
such that both versions are recoverable) cause problems for the Publish code,
even before MDMF landed. Might be related to refs #1390 and refs #1042.
