mbedtls_ssl_ticket_free() function

Context to be cleaned up

Initialize a ticket context. (Just make it ready for mbedtls_ssl_ticket_setup() or mbedtls_ssl_ticket_free().)

Rotate session ticket encryption key to new specified key. Provides for external control of session ticket encryption key rotation, e.g. for synchronization between different machines. If this function is not used, or if not called before ticket lifetime expires, then a new session ticket encryption key is generated internally in order to avoid unbounded session ticket encryption key lifetimes.

Prepare context to be actually used
