scd: Support for SmartCard-HSM

* scd/app-sc-hsm.c: New.
* scd/app.c (select_application, get_supported_applications): Register
new app.

--
Add a read/only driver for scdaemon that provides access to keys and
certificates on a SmartCard-HSM (www.smartcard-hsm.com).

The driver supports RSA and ECC keys on SmartCard-HSM cards and
USB-Sticks.

The driver does not yet support the MicroSD edition.
