Add new initializers for cipher operation objects and use them in our tests and library code. Prefer using the macro initializers due to their straightforwardness.

|
*
|
|
* \note This file may not be included directly. Applications must
|
|
* include psa/crypto.h.
|
|
*
|
|
* This file contains the definitions of some data structures with
|
|
* implementation-specific definitions.
|
|
*
|
|
* In implementations with isolation between the application and the
|
|
* cryptography module, it is expected that the front-end and the back-end
|
|
* would have different versions of this file.
