mechanism Context provides.

We temporarily put our own global table in place and restore whatever
we overloaded afterwards.
\CONTEXT\ modules each have a custom logging mechanism that can be
enabled for debugging.
In order to fake the presence of this facility we need to define at
least the function \verb|logs.reporter|.
For now it’s sufficient to make it a reference to \verb|mklog| as
defined above.
