  sender threads

Git head information in version
- About dialog now shows the git head
- git head check has been improved to point to the head rather than the
  previous commit

Node negotiation error handling
- complete the version and SSL handshake first, and only then feed
  errors into the stream and close connection
- this allows more accurate error handling on both sides
- also the timeOffset error trigger is now more accurate, but requires
  more nodes to upgrade

Set SSL socket to blocking
- otherwise the error handling gets too complicated

MarkAllUnread sqlite argument limit
- shouldn't crash anymore if there are too many messages to mark read

Timeout handling and ping
- timeouts after the connection is established will trigger a ping
- previously they were handled as unrecoverable errors

Retry for certain non-blocking operations
- sometimes on read, EWOULDBLOCK is returned. It should retry. A timeout
  is handled separately

Improved stream handling
- version command sends list of all participating streams
- biginv sends lists of hosts for all streams the peer wants (plus
  immediate children)
- objects will spread to all peers that advertise the associated stream
- please note these are just network subsystem adjustments, streams
  aren't actually usable yet

Network subsystem freezing fixes
- queues were too short
- some error handling was missing
- remove nonblocking repeats in receive data thread
- singleCleaner shouldn't wait unnecessarily

Less verbose SSL handshake reporting
- if SSL handshake fails, we don't need to stack trace because we know
  where it's happening. Only report the error string.

Fix false error about wrong stream
- sendinv and sendaddress are sometimes being sent to connections that
  haven't been established yet, resulting in complaints about stream
  mismatch. The error should only be displayed once the connection has
  been established and the remote node provides its stream number

Download/upload shutdown fixes
- Missing renamed to PendingDownload
- PendingDownload now only retries 3 times rather than 6 to dowload an
  object
- Added PendingUpload, replacing invQueueSize
- PendingUpload has both the "len" method (number of objects not
  uploaded) as well as "progress" method, which is a float from 0
  (nothing done) to 1 (all uploaded) which considers not only objects
  but also how many nodes they are uploaded to
- PendingUpload tracks when the object is successfully uploaded to the
  remote node instead of just adding an arbitrary time after they have
  been send the corresponding "inv"
- Network status tab's "Objects to be synced" shows the sum of
  PendingUpload and PendingDownload sizes

Expire objects that we're unable to receive
- sometimes a node would send an "inv" about an object but then not
  provide it when requested. This could be that it expired in the
  meantime or it was an attack or a bug. This patch will forget that the
  object exists if was requested too many times and not received.

Better tracking in downloading objects
- remember what was requested from which node
- remember if it was received
- re-request object if we haven't received any new object for more than
  a minute

Objects to be downloaded optimising
- treat requested but never arrived objects as expired. This is how it
  worked before the refactoring. Without this, the list won't go to
  zero.

Performance tuning objects to be downloaded
- rely on dict quasi-random order instead of an additional shuffle
- request an object once per minute
- stop check after count objects have been found

Objects to be downloaded fixes
- tries to avoid calling senddata it it would block receiveDataThread,
  allowing fore more asynchronous operation
- request objects in chunks of 100 (CPU performance optimisation)

Refactor objects to be downloaded
- moved logic into a Missing singleton
- shouldn't try to download duplicates anymore, only requests a hash
  once every 5 minutes and not from the same host
- removed obsoleted variables
- the "Objects to be synced" in the Network tab should now be correct
- removed some checks which aren't necessary anymore in my opinion
- fix missing self in Throttle (thanks landscape.io)

Transfer speed improvements
- send buffer to send multiple commands in one TCP packet
- recv/send operation size now based on bandwith limit
- send queue limited to 100 entries
- buffer getdata commands to fill send queue, instead of waiting for the
  data packet to arrive first (i.e. allow getdata to work asynchronously)
