Changes (by jelte):

 * owner:  jelte => UnAssigned
 * status:  assigned => reviewing


Comment:

 ready for review.

 First commit is the actual implementation.
 Second one is to be able to configure and change the value (lots of small
 changes to propagate it all the way from auth_srv to TCPServer, and a few
 tricks to get it working there).
 Commits 3 and 4 are documentation.

 Proposed changelog:
 [bug] jelte
 b10-auth no longer keeps incoming TCP connections open if no (or not
 enough) data is sent by the client. The timeout value is configurable.
