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

Try new ports of binding fails
- API and BM protocol will try random ports for binding if those
configured are occupied

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

Per connection node id part 2

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

Asyncore fixes
- fix broken loops
- optimise I/O tests

Asyncore update
- get rid of per-connection writeQueue/receiveQueue, and instead use
strings and locking
- minor code cleanup
- all state handlers now should set expectBytes
- almost all data processing happens in ReceiveDataThread, and
AsyncoreThread is almost only I/O (plus TLS). AsyncoreThread simply
puts the connection object into the queue when it has some data for
processing
- allow poll, epoll and kqueue handlers. kqueue is untested and
unoptimised, poll and epoll seem to work ok (linux)
- stack depth threshold handler  in decode_payload_content, this is
recursive and I think was causing occasional RuntimeErrors. Fixes #964
- longer asyncore loops, as now data is handled in ReceiveDataThread
- randomise node order when deciding what to download. Should prevent
retries being stuck to the same node
- socks cleanup (socks5 works ok, socks4a untested but should work too)

Migrate antiIntersectionDelay to asyncore
- implemented by ignoring getdata during the delay rather than sleeping
as it was in the threaded model
- it can happen that a valid getdata request is received during the
delay. A node should be implemented in a way that retries to download,
that may not be the case with older PyBitmessage versions or other
implementations

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

Add ratings to peers
- outbound peers now have a rating
- it's also shown in the network status tab
- currently it's between -1 to +1, changes by 0.1 steps and uses a
hyperbolic function 0.05/(1.0 - rating) to convert rating to
probability with which we should connect to that node when randomly
chosen
- it increases when we successfully establish a full outbound connection
to a node, and decreases when we fail to do that
- onion nodes have priority when using SOCKS

AddrThread
- this thread is for spreading new/updated addresses in active
connections, analogous to the InvThread
- it doesn't do anything yet, this is just a dummy queue at the moment
