 Ignore-this: da66ee51c894eaa4e862e2dffb458acc
 
 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.

 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

[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.

 This also adds tests for all those cases, and fixes an omission in uri.py
 that broke parsing of DIR2-MDMF-Verifier and DIR2-CHK-Verifier.
