Library initialization

Library initialization.

Applications must call this function before calling any other function in this module.

Applications may call this function more than once. Once a call succeeds, subsequent calls are guaranteed to succeed.

If the application calls other functions before calling psa_crypto_init() , the behavior is undefined. Implementations are encouraged to either perform the operation as if the library had been initialized or to return PSA_ERROR_BAD_STATE or some other applicable error. In particular, implementations should not return a success status if the lack of initialization may have security implications, for example due to improper seeding of the random number generator.
