New logging approach in order to reduce imports from submodules
and use logging without risk of circular import. Only subpackage
that imports from debug is bitmessageqt - because it also uses
debug.resetLogging().
Instead of from debug import logger is now recommended to use:

import logging

logger = logging.getLogger('default')

All subclasses of StoppableThread now have a logger attribute.
All threading related stuff except for set_thread_name()
was moved from helper_threading to network.threads.

Fixed two my mistakes from previous edit of debug in a1a8d3a:

 - logger.handlers is not dict but iterable
 - sys.excepthook should be set unconditionally

Separate protocol processing exceptions
- exceptions thrown by the state methods are separated from missing
  connections or states. This allows more accurate error reporting

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

stuck

receivedata thread

Asyncore performance optimisation
- don't transfer unnecessary amount of bytes from network buffers
- slice buffer more efficiently if it results in an empty buffer

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

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)

asyncore fixes
- bm headers and commands are only read up to expected length.
On a very fast connection (e.g. local VM), reading verack
also read a part of the TLS handshake
- some debugging info moved from print to logger.debug
- tls handshake cleanup
