Revert "Use sortedcontainers instead of blist"
...
This reverts commit 9fbe70a7dc
.
It turns out that sortedcontainers.SortedDict is not an exact match for
blist.sorteddict; in particular, `popitem()` removes things from the opposite
end of the dict.
This is trivial to fix, but I want to add some unit tests, and potentially some
more thought about it, before we do so.

ResponseCache: fix handling of completed results
...
Turns out that ObservableDeferred.observe doesn't return a deferred if the
result is already completed. Fix handling and improve documentation.

Update canonicaljson dependency
...
1.1.0 and 1.1.1 were broken, so we're updating this to help people make sure
they don't end up on a broken version.
Also, 1.1.0 is speedier...

Refactor ResponseCache usage
...
Adds a `.wrap` method to ResponseCache which wraps up the boilerplate of a
(get, set) pair, and then use it throughout the codebase.
This will be largely non-functional, but does include the following functional
changes:
* federation_server.on_context_state_request: drops use of _server_linearizer
which looked redundant and could cause incorrect cache misses by yielding
between the get and the set.
* RoomListHandler.get_remote_public_room_list(): fixes logcontext leaks
* the wrap function includes some logging. I'm hoping this won't be too noisy
on production.

Don't disable GC when running on PyPy

PyPy's incminimark GC can't be triggered manually. From what I observed
there are no obvious issues with just letting it run normally. And
unlike CPython, it actually returns unused RAM to the system.

In DomainSpecificString, override __repr__ in addition to __str__
...
For some reason, string interpolation on a DomainSpecificString object
like "%r" % (domainSpecificStringObj) fails under PyPy, because the
default __repr__ implementation wants to iterate over the object. I'm
not sure why that happens, but overriding __repr__ instead of __str__
fixes this problem, and is arguably the more appropriate thing to do
anyways.

Use psycopg2cffi module instead of psycopg2 if running on pypy

The psycopg2 package isn't available for PyPy. This commit adds a check
if the runtime is PyPy, and if it is uses psycopg2cffi module in favor
of psycopg2. This is almost a drop-in replacement, except for one place
where an additional cast to string is required.

Replace old-style raise with six.reraise
...
The old style raise is invalid syntax in python3. As noted in the docs,
this adds one more frame in the traceback, but I think this is
acceptable:
<ipython-input-7-bcc5cba3de3f> in <module>()
16 except:
17 pass
---> 18 six.reraise(*x)
/usr/lib/python3.6/site-packages/six.py in reraise(tp, value, tb)
691 if value.__traceback__ is not tb:
692 raise value.with_traceback(tb)
--> 693 raise value
694 finally:
695 value = None
<ipython-input-7-bcc5cba3de3f> in <module>()
9
10 try:
---> 11 x()
12 except:
13 x = sys.exc_info()
Also note that this uses six, which is not formally a dependency yet,
but is included indirectly since most packages depend on it.

Use static JSONEncoders
...

Add counter metrics for calculating state delta

This will allow us to measure how often we calculate state deltas in
event persistence that we would have been able to calculate at the same
time we calculated the state for the event.
