Hmmm.

There should be no pcsc wrapper in master anymore.  We don't need it
after the switch to npth.  I guess we simply forgot to remove the need
for the wrapper.

The wrapper was needed because it is not possible to use Pth and pthread
together.  libpcsclite uses pthread.  nPth solves the problem by
internally using pthread.



Salam-Shalom,
