mds: Apply serial number arithmetic for sequence counter [#1960]
This patch applies the serial number arithmetic for the flow control
sequence number, referenced to RFC1982.
This is only temporary patch, a proper one could be made in /base
with template for others type, e.g uint32. Then mds reuses it from
/base.

mds: Add configurable parameters [#1960]
This patch makes the solution of TIPC buffer overflow configurable,
as well as the ack timeout/ack size.
For example:
The service config file can export the following environment variables
export MDS_TIPC_FCTRL_ENABLED=1
export MDS_TIPC_FCTRL_ACKTIMEOUT=1000
export MDS_TIPC_FCTRL_ACKSIZE=1
If MDS_TIPC_FCTRL_ACKTIMEOUT, MDS_TIPC_FCTRL_ACKSIZE are not specified,
the default values are used.

mds: Add timeout for ack message [#1960]
If the ack size is configured greater than 1, there should be a timeout
at receiver ends to send the ack message back to senders.
The ack message timeout utilizes the poll timeout in flow control thread
to make mds lightweight (in contrast to additional timer threads).

mds: Add implementation for TIPC buffer overflow solution [#1960]
This is a collaborative patch of two participants:Thuan, Minh.
Main changes:
- Add mds_tipc_fctrl_intf.h, mds_tipc_fctrl_intf.cc: These two files
introduce new functions which are called in mds_dt_tipc.c if the flow
control is enabled
- Add mds_tipc_fctrl_portid.h, mds_tipc_fctrl_portid.cc: These files
implements the tipc portid instance, which supports the sliding window,
mds msg queue
- Add mds_tipc_fctrl_msg.h, mds_tipc_fctrl_msg.cc: These files define
the event and messages which are used for this solution.

** [tickets:#1960] MDS: MDS does not handle dropped TIPC packages **
**Status:** fixed
**Milestone:** 5.19.10
**Created:** Fri Aug 19, 2016 08:39 AM UTC by Hans Nordebäck
**Last Updated:** Mon Sep 02, 2019 12:55 AM UTC
**Owner:** Minh Hon Chau
TIPC is run in connection less mode by OpenSAF, i.e. SOCK_RDM, reliable
datagram where ordering is guaranteed but packages can be dropped at e.g.
overload situations.
This is not handled by OpenSAF and may cause undetermined behaviour in the
system.
