I was thinking of having a static messaging_context pointer in
dbwrap_open.c and having to initialize that.

The second option would be passing down the messaging context as
arguments, but that might get tricky with shared libraries.

And the third option would be going back to having only one "common"
messaging context and just add cmdline wrapper functions to initialize
the common context with proper error handling.
