ccid: add ccid-card-emulated device

This devices uses libcacard (internal) to emulate a smartcard conforming
to the CAC standard. It attaches to the usb-ccid bus. Usage instructions
(example command lines) are in the following patch in docs/ccid.txt. It
uses libcacard which uses nss, so it can work with both hw cards and
certificates (files).
