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

Remove obsolete code
- PendingDownload and PendingUpload in inventory.py are obsolete
- the replacement functions only provide lengths and are in
  network/stats.py

Dandelion update
- dandelion fixes
- try to wait as long as possible before expiration if there are no
outbound connections
- expire in invThread rather than singleCleaner thread
- deduplication of code in inv and dinv command methods
- turn on by default, seems to work correctly now
- turn off dandelion if outbound connections are disabled
- start tracking downloads earlier, and faster download loop
- remove some obsolete lines
- minor PEP8 updates

Dandelion fixes
- dandelion would always think there is a cycle and trigger fluff
- cycle fluff trigger didn't correctly re-download and re-announce the
object. Now it remembers between (d)inv and object commands that it's
in a fluff trigger phase.

Pending download stats optimisations
- tracks separately a global list for a faster sum. Needs slightly
more memory

Dandelion updates
- fixes and feedback from @gfanti and @amiller
- addresses #1049
- minor refactoring
- two global child stems with fixed mapping between parent and
child stem
- allow child stems which don't support dandelion
- only allow outbound connections to be stems
- adjust stems if opening/closing outbound connections (should
allow partial dandelion functionality when not enough outbound
connections are available instead of breaking)

Dandelion++ implementation
- untested, some functionality may be missing, don't turn on
- also, it randomises upload of requested objects
- affects #1049

Download thread updates
- now tracks downloads globally too, so it doesn't request the same
object from multiple peers at the same time
- retries at the earliest every minute
- stops trying to download an object after an hour
- minor fixes in retrying downloading invalid objects

- separate download thread
- connection pool init moved to main thread
