Synchronize access to COBIA objects from COM

[jasper]

COMBIA registers DEFAULT threaded COBIA objects as Both, which implies the COM side may be instantiated as MTA, which in turn implies multiple concurrent incoming calls are in theory possible. COMBIA should shield against this.

This should be one synchronization object (e.g. std::mutex) per PMC objects - including all its primary PMC objects to agree with DEFAULT threading model.

Is this really within the milestone Maintenance of Phase II? Resolution of this waits for COBIA Threading Models to be formally approved while M&T SIG is still working on the document describing these, and a RFC phase will take place once M&T SIG has completed the document. The design of COBIA Threading Models is a task in parallel to COBIA Phase III. So should the milestone for this ticket be Phase III or when the WP1 Phase III branch will be merged with Phase II trunk?

My issue is that currently COMBIA advertises COBIA PMCs as Both (in Phase II). That is why it would be reasonable to fix it now.
