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)

Asyncore updates 
- reduce buffer size to 128kB (was 2MB)
- IP address handling use str instead of buffer (the latter, even
though it should be faster, breaks the code on Windows)
- read up to full buffer after fully established (otherwise
downloads become too slow due to the loop time). This reverts
a change made in d28a7bfb86

Peer discovery updates 
- allow loopback addresses, now you can bind different loopback IP
addresses on a single system and they will auto-cross-connect
- always listen for discovery on 0.0.0.0
- [network] - bind now also applies for the TCP socket as well as UDP
socket
- closing socket iterator fix

Change peer discovery tracking from queue to a dict 
- with a queue, a situation could occur when new entries are appended
but nothing is polling the queue

Asyncore processing thread synchronisation 
- threre was a synchronisation problem where one thread could process
more data than another thread was expecting, leading to the thread
crashing

Make protocol decoder less recursive 
- apparently, recursion has bad performance in Python, so the decoder is
now flat, except when parsing "version" command

Randomise node id 
- in order to detect if it's connected to to itself, PyBitmessage now
uses a per-connection id rather than a global one
