m3ua: fix missing decoding of message priority & network indicator flag

The missing parenthesis always or'ed with a 0x0 into the sio field because
of operator precendence. Left shift is stronger than a binary and.

tcap_as_loadshare: Fix compare ignoring non-TCAP messages and remove assert

The previous check in asp_loadshare_tcap_sccp()  was was never true because it
checked msg class twice instead of class and type.

Also remove the OSMO_ASSERT in send_back_udts() limiting the function to
CL/DT messages.

Add DSCP configuration support for server transport role

Introduce VTY command to configure the Differentiated Services Code
Point (DSCP) values for transport "role" server.

The configured DSCP value is applied to the listener socket. Incoming
socket connections will then automatically inherit these DSCP settings
from the listener socket.

It is not (yet) possible to configure DSCP values for individual active
server connections. The setting applies globally via the listener.
A later patch will allow DSCP configuration of each individual ASP.

Add DSCP configuration support for each individual ASP

Introduce VTY command to configure the Differentiated Services Code
Point (DSCP) values for each Application Server Process.

If the ASP connection has the role "server", it will inherit the DSCP
settings of the listener, unless it is configured at the ASP connection.
