Check and set AlgorithmIdenfier parameters for key wrap algorithms.
Currently these just set parameters to NULL.

Bug would emerge when XTS is added to bsaes-armv7.pl. Pointed out by
Ard Biesheuvel of Linaro.

Add support for key wrap algorithms via EVP interface.

Generalise AES wrap algorithm and add to modes, making existing
