Allow separate proxy for onions

onionsockshostname and onionsocksport. These allow to separate
connectivity types for onion and non-onion addresses, e.g. connect to
clear nodes over clearnet and onions over tor

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

No connection CPU hog fix 
- the previous fix was incomplete, it shouldn't consume excessive
resources now when there are no connections

Bandwidth limit optimisation 
- should be slightly more accurate and use slightly fewer resources
 2018-01-02 15:24:47 +01:00
Peter Šurda 8788f2d349
Server full and duplicate handling 
- will try to report "Server full" over protocol for 10 extra
connections over limit, instead of simply dropping them
- if connected to the same host inbound and outbound, handle as server
full (prevents duplicate connections)
 2018-01-02 14:29:21 +01:00

Download optimisations 
- don't make empty download requests
- use smaller chunks when they can be spread across multiple
connections

Close filehandles on connection reaping 
- I thought this is done automatically through garbage collection, but I
think as the channel is still assigned in the asyncore map, it needs
to be done manually. Basically filehandle limit exceeded and it
crashed
 2017-11-19 00:05:55 +01:00
Peter Šurda 5e042b76e7
Typo 
- missing brackets

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.

 2017-11-17 19:49:51 +01:00
Peter Šurda 5a787f41d2
Socket closing changes 
- explicit close only through asyncore error handler
- implicit close through garbage collector
- avoid duplicate closing
 2017-11-17 13:37:51 +01:00

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

Stop downloading objects with insufficient PoW 
- object with insufficient PoW weren't correctly detected and it
