We can do with a forward declaration instead to reduce
the dependency, and include reader_concurrency_semaphore.hh
in test/lib/reader_permit.cc instead.
We need to include "../../reader_permit.hh" to get the
definition of class reader_permit. We need the include
path to prevent recursive include (or rename test/lib/reader_permit.hh
but this creates a lot of code churn).

This contains a reader concurrency semaphore for the tests, that they
can use to obtain a valid permit for reads. Soon we are going to start
working towards a point where all APIs taking a permit will require a
valid one. Before we start this work we must ensure test code is able to
obtain a valid permit.
