winscard: add pcsc-lite helpers for upcoming(?) implementation

Hi,

looking for PCSC-card-reader support in Wine, I came across old mails from 2007.
http://www.winehq.org/pipermail/wine-devel/2007-May/057052.html

What's the current state of PCSC support in Wine? When I recently looked,
winscard seemed full of stubs.

OTOH, there's a company
http://www.starmoney.de/index.php?id=243
that seems to use Wine (and Darwine?) with card readers to make
its software available for Linux & Mac.  Also seems ~2007.

I believe that a winscard<->PCSC<->PCSC-Lite bridge would be much
easier to achieve than USB support in Wine.

Thanks for your help,
 Jörg Höhle
