Add limited support for QoS changes

Browse source 
This commit adds support for changing all mutable QoS except those that
affect reader/writer matching (i.e., deadline, latency budget and
partition).  This is simply because the recalculation of the matches
hasn't been implemented yet, it is not a fundamental limitation.

Implementing this basically forced fixing up a bunch of inconsistencies
in handling QoS in entity creation.  A silly multi-process ping-pong
test built on changing the value of user data has been added.
