Dandelion fixes
- expiration wasn't handled correctly
- objects with no child stems never expired. While this is better for
  anonymity, it can cause objects getting stuck
- upon expiration the nodes weren't marked as not having the object, causing it
  to not be advertised
- I haven't tested it but at least I don't think can make things worse

getdata performance optimisation
- reduce number of calls to time.time()
- no need to shuffle, that's done by the upload thread
- get rid of unused import

Put uploads into a separate thread
- instead of being processed in the ReceiveQueue thread, uploads are now done
  in a dedicated thread. Only the parsing is done in ReceiveQueue thread.
- the UploadThread is modelled based on the DownloadThred, but simpler.
- it checks for intersection attack, eliminates duplicates and restricts the
  write buffer size to 2MB (may still grow slightly higher if too many big
  objects are requested, but the absolute limit appears to be about 4.5MB in the
  worst case scenario).
- the restriction of the write buffer may cause some upload throttling (to
  about 2MB per second per connection), but can be optimised later
- fixes #1414

Added tests for knownnodes:
- import of pickled knownnodes;
  - default knownnodes if nothing imported;
  - knownnodes starvation (#1335), demanded changes in networkthread.

Download fixes
- in corner cases, download request could have contained an incorrect
  request length. I haven't actually checked if this can be triggered
  though
- wait for downloading until anti intersection delay expires. Doesn't
  necessarily mean that it will always avoid peer's anti intersection
  delay, but it's close enough
- tracks last time an object was received. If it was too long time ago,
  reset the download request queue. This avoid situations like when a
  request gets ignored during the anti intersection delay, but it will
  keep thinking there are still pending requests as long as not all
  missing objects have been requested. This caused staggered download
  (request 1000 items, wait 1 minute, request 1000 more, wait another
  minute, ...)
- with these fixes, you should end up downloading as fast as your
  network and CPU allow
- best tested with trustedpeer

Memory leak (kind of) fix
- objectsKnownToThem is supposed to track if it's necessary to send inv
  commands to a peer
- it is supposed to enter garbage collection after 1 hour
  (ObjectTracker.trackingExpires)
- due to peer not announcing all objects, or announcing them before we
  announce, this contains excessive number of entries after connection
  is fully established.
- profiling revealed that this creates unnecessary memory to be kept
  allocated
- this patch will prevent tracking of entries sent during bigInv,
  reducing the memory "leak"
- it is possible, in theory, that this does have some negative effect,
  like increased bandwidth or neglecting to announce some invs. It
  probably doesn't though as my review of objectsKnownToThem occurrences
  didn't reveal any such case, and since the dict didn't track fully
  accurately anyway (so it would have already been broken if it was a
  problem), I consider it an acceptable risk at the moment. If it indeed
  causes problems, they can be solved separately
- I tested this on one of the bootstrap servers with little memory, and
  it increased the number of connections than can be handled by a factor
  of about 3.5
