fix for this bug.
Description of problem:
Using a spice smartcard connection with AET middleware doesn't work correctly due to the middleware reporting it supports CKM_RSA_X_509 when it doesn't.
fix is attached. sent to qemu upstream. (qemu mailing list is used for libcacard related fixes since libcacard is part of qemu code repository.)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. start qemu with emulated smartcard (['-chardev', 'spicevmc,id=smartcard,debug=3,name=smartcard', '-device', 'usb-ccid,debug=1,id=ccid', '-device', 'ccid-card-passthru,debug=1,chardev=smartcard'])
2. start spicec with --enable-smartcard
3. smartcard appears in vm, but cannot complete a pk11_listcerts
requests pin and shows certs.
Adding Rebase keyword. Since the previous version of libcacard (0.1.2-2) the sources have moved from an independent repository to be part of the qemu repository. This was not just a copy operation, but included fixes for reusing qemu infrastructure and applying qemu coding style, and a number of bug fixes have also been done on that code base. As a result a rebase of libcacard is recommended. It will include a fix for this bug.

AET middleware reports support for CKM_RSA_X_590 while failing when requested to use it.
libcacard based virtual card using a real AET middleware on the host fails to do any vcard_emul_rsa_op, failing for example pk11_listcerts.
libcacard now handles failure in CKM_RSA_X_590 by falling back to CKM_RSA_PKCS.
Using AET backed virtual cards works, including pk11_listcerts or any other operation.
