block: expose crypto option names / defs to other drivers
The block/crypto.c defines a set of QemuOpts that provide parameters for encryption. This will also be needed by the qcow/qcow2 integration, so expose the relevant pieces in a new block/crypto.h header. Some helper methods taking QemuOpts are changed to take QDict to simplify usage in other places.
