Alter the signature of set_shareholders in IEncoder to add a 'servermap' parameter, which gives IEncoders enough information to perform a sane check for servers_of_happiness.

Revisions of the #778 tests, per reviewers' comments
- Fix comments and confusing naming.
- Add tests for the new error messages suggested by David-Sarah
and Zooko.
- Alter existing tests for new error messages.
- Make sure that the tests continue to work with the trunk.
- Add a test for a mutual disjointedness assertion that I added to
upload.servers_of_happiness.
- Fix the comments to correctly reflect read-onlyness
- Add a test for an edge case in should_add_server
- Add an assertion to make sure that share redistribution works as it
should
- Alter tests to work with revised servers_of_happiness semantics
- Remove tests for should_add_server, since that function no longer exists.
- Alter tests to know about merge_peers, and to use it before calling
servers_of_happiness.
- Add tests for merge_peers.
- Add Zooko's puzzles to the tests.
- Edit encoding tests to expect the new kind of failure message.
- Edit tests to expect error messages with the word "only" moved as far
to the right as possible.
- Extended and cleaned up some helper functions.
- Changed some tests to call more appropriate helper functions.
- Added a test for the failing redistribution algorithm
- Added a test for the progress message
- Added a test for the upper bound on readonly peer share discovery.
This patch modifies the regular expression used for verifying of '--node-url'
parameter. Support for accessing a Tahoe gateway over HTTPS was already
present, thanks to Python's urllib.

backupdb.did_create_directory: use REPLACE INTO, not INSERT INTO + ignore error
This handles the case where we upload a new tahoe directory for a
previously-processed local directory, possibly creating a new dircap (if the
metadata had changed). Now we replace the old dirhash->dircap record. The
previous behavior left the old record in place (with the old dircap and
timestamps), so we'd never stop creating new directories and never converge
on a null backup.
docs: install.html -> quickstart.html
It is not called "installing" because that implies that it is going to change the configuration of your operating system. It is not called "building" because that implies that you need developer tools like a compiler. Also I added a stern warning against looking at the "InstallDetails" wiki page, which I have renamed to "AdvancedInstall".
licensing: phrase the OpenSSL-exemption in the vocabulary of copyright instead of computer technology, and replicate the exemption from the GPL to the TGPPL
docs: a few small edits to try to guide newcomers through the docs
These edits were suggested by my watching over Jake Appelbaum's shoulder as he completely ignored/skipped/missed install.html and also as he decided that debian.txt wouldn't help him with basic installation. Then I threw in a few docs edits that have been sitting around in my sandbox asking to be committed for months.

Change OphandleTable to use a deterministic clock, so we can test it
To test the changes for #577, we need a deterministic way to simulate
the passage of long periods of time. twisted.internet.task.Clock seems,
from my Googling, to be the way to go for this functionality. I changed
a few things so that OphandleTable would use twisted.internet.task.Clock
when testing:
* WebishServer.__init___ now takes an optional 'clock' parameter,
* which it passes to the root.Root instance it creates.
* root.Root.__init__ now takes an optional 'clock' parameter, which it
passes to the OphandleTable.__init__ method.
* OphandleTable.__init__ now takes an optional 'clock' parameter. If
it is provided, and it isn't None, its callLater method will be used
to schedule ophandle expirations (as opposed to using
reactor.callLater, which is what OphandleTable does normally).
* The WebMixin object in test_web.py now sets a self.clock parameter,
which is a twisted.internet.task.Clock that it feeds to the
WebishServer it creates.
Tests using the WebMixin can control the passage of time in
OphandleTable by accessing self.clock.

code coverage: replace figleaf with coverage.py, should work on py2.6 now.
It still lacks the right HTML report (the builtin report is very pretty, but
lacks the "lines uncovered" numbers that I want), and the half-finished
delta-from-last-run measurements.
docs: install.html: recommend Python 2.5 (because I can build extension modules for it with mingw), architecture.txt: point out that our Proof of Retrievability feature is client-side-only
docs: a few edits to architecture.txt, most significantly highlighting "future work" to avoid confusing it with the current version, and adding a "future work" about a random-sampling Proof of Retrievability verifier
immutable: downloader accepts notifications of buckets even if those notifications arrive after he has begun downloading shares.
This can be useful if one of the ones that he has already begun downloading fails. See #287 for discussion. This fixes part of #287 which part was a regression caused by #928, namely this fixes fail-over in case a share is corrupted (or the server returns an error or disconnects). This does not fix the related issue mentioned in #287 if a server hangs and doesn't reply to requests for blocks.
tests: stop being surprised that Nevow no longer prints out warnings when it tries to find its static files
Unless we are using a sufficiently new version of Nevow, in which case if it prints out warnings then this is a hard test failure. :-)
immutable: download from the first servers which provide at least K buckets instead of waiting for all servers to reply
This should put an end to the phenomenon I've been seeing that a single hung server can cause all downloads on a grid to hang. Also it should speed up all downloads by (a) not-waiting for responses to queries that it doesn't need, and (b) downloading shares from the servers which answered the initial query the fastest.
Also, do not count how many buckets you've gotten when deciding whether the download has enough shares or not -- instead count how many buckets to *unique* shares that you've gotten. This appears to improve a slightly weird behavior in the current download code in which receiving >= K different buckets all to the same sharenumber would make it think it had enough to download the file when in fact it hadn't.
This patch needs tests before it is actually ready for trunk.
