mutable/retrieve: handle the case where self._read_length is 0.
Note that the downloader will still fetch a segment for a zero-length
read, which is wasteful. Fixing that isn't specifically required to fix
#1512, but it should probably be fixed before 1.9.

test_mutable.Update: only upload the files needed for each test. refs #1500
This first step shaves 15% off the runtime: from 139s to 119s on my laptop.
It also fixes a couple of places where a Deferred was being dropped, which
would cause two tests to run in parallel and also confuse error reporting.

Let Uploader retain History instead of passing it into upload(). Fixes #1079.
This consistently records all immutable uploads in the Recent Uploads And
Downloads page, regardless of code path. Previously, certain webapi upload
operations (like PUT /uri/$DIRCAP/newchildname) failed to pass the History
object and were left out.

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

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].

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.

Implementation, tests and docs for blacklists. This version allows listing directories containing a blacklisted child. Inclusion of blacklist.py fixed. fixes #1425
doc: eliminate the phrase "rootcap" from doc/frontends/FTP-and-SFTP.rst
Two different people have asked me for help, saying they couldn't figure out what a "rootcap" is. Hopefully just calling it a "cap" will make it easier for them to find out from the other docs what it is.
These are their own patch because they cut across a lot of the changes
I've made in implementing MDMF in such a way as to make it difficult to
split them up into the other patches.
- Learn how to create MDMF files and directories through the
mutable-type argument.
- Operate with the interface changes associated with MDMF and #993.
- Learn how to do partial updates of mutable files.
mutable/layout: Define MDMF share format, write tools for working with MDMF share format
The changes in layout.py are mostly concerned with the MDMF share
format. In particular, we define read and write proxy objects used by
retrieval, publishing, and other code to write and read the MDMF share
format. We create equivalent proxies for SDMF objects so that these
objects can be suitably general.
mutable/filenode: Modify mutable filenodes for use with MDMF
In particular:
- Break MutableFileNode and MutableFileVersion into distinct classes.
- Implement the interface modifications made for MDMF.
- Be aware of MDMF caps.
- Learn how to create and work with MDMF files.

Remove Non-Profit Open Software License from the set of 'added permission' licenses. Although it actually does qualify as an Open Source license (because it allows relicensing under plain OSL), its wording is unclear and could easily be misunderstood, and it contributes to incompatible license proliferation.
