Hello Neels Hofmeyr, Harald Welte, Jenkins Builder, 

I'd like you to reexamine a change. Please visit

to look at the new patch set (#3).

Change subject: GSUP: implement TCAP-like session management
......................................................................

GSUP: implement TCAP-like session management

Unlike TCAP/MAP, GSUP is just a transport layer without the
dialogue/context. This prevents us from having session based
communication, required e.g. for USSD. But we can emulate
TCAP dialogue by adding additional IEs, which would allow
to relate each message to a particular session.

This change introduces the following IEs:

  - OSMO_GSUP_SESSION_ID_IE,
  - OSMO_GSUP_SESSION_STATE_IE,

which optionally can be used to indicate that the message is
related to a session with given ID, and to manage session
state, i.e. initiate, continue, and finish.
