Re: [epics-modules/asyn] Throw exception if we can't register interfaces (#43)

Maybe it’s time for the IOC shell to actually look at the return values from the functions it calls.  In conjunction with some sort of equivalent to the UNIX shell ‘-e’ flag it could prevent st.cmd scripts from proceeding in the face of error returns from configuration functions.

There are 3 places where I think it is OK to use exceptions now.

• In constructor when a serious error occurs
• internally in code where all exceptions will be caught. asynPortDriver does this now.
• In drivers or plugins where the vendor library throws exceptions. All exceptions must be caught in this case.
