and silc_crypto_uninit, and silc_crypto_stack.
Changed SILC PKCS API asynchronous so that accelerators can be
used, and added SilcStack support to many routines.
Rewrote PKCS, cipher, hash and HMAC registering/unregistering.
silc_xxx_register_default does not call silc_xxx_register anymore.
User can enforece the order of algorithms by calling silc_xxx_register
in the order they want.
Changed silc_rng_get_rn_data to non-allocating.

+/****h* silccrypt/SILC Crypto Toolkit API
+ *
+ * DESCRIPTION
+ *
+ * This interface is used to initialize and uninitialize the SILC Crypto
+ * Toolkit. SILC Crypto Toolkit is initialized by calling the
+ * silc_crypto_init function. It needs to be called only once per-process
+ * but must be called before any crypto functions are used.
+ *
+ * In initialization all builtin ciphers, hash functions, HMACs, PKCSs
+ * and other algorithms will be registered to the crypto library. If user
+ * wants to register new algorithms or change the order of the automatically
+ * registered algorithms, user can do this by re-registering the algorithms
+ * in desired order.
+ *
+ * A global SilcStack, a memory pool, can be associated with the Crypto
+ * Toolkit. If it is set in initialization, all routines in the Crypto
+ * Toolkit will use that stack as its memory source. Some interfaces and
+ * libraries in the SILC Crypto Toolkit support also providing the SilcStack
+ * as an additional argument, in which case a different stack from the global
+ * one can be used.

+ *
+ * SilcBool silc_crypto_init(SilcStack stack);
+ *
+ * DESCRIPTION
+ *
+ * Initialize SILC Crypto Toolkit. This must be called once for every
+ * process. It initializes all libraries and registers builtin algorithms
+ * to the crypto library. If user wants to change the order of the
+ * registered algorithms, user can re-register them with their
+ * corresponding registering functions in the wanted order.
+ *
+ * If `stack' is non-NULL, it will be used by all libraries as their main
+ * source for memory. A child stack is created from the `stack'. When
+ * silc_crypto_uninit is called the allocated memory is returned back to
+ * `stack' and the caller must then free `stack'.
+ *
+ * Returns FALSE if the initialization failed. If this happens the
+ * SILC Crypto Toolkit cannot be used.

+ * SilcStack silc_crypto_stack(void);
+ *
+ * DESCRIPTION
+ *
+ * Returns the SILC Crypto Toolkit's global stack, the memory pool.
+ * Returns NULL if the stack does not exist.
+ *
+ * A common way to use this is to allocate a child stack from the
+ * returned stack. That operation is thread-safe, usually does not
+ * allocate any memory and is very fast. Another way to use the stack
+ * is to push it when memory is needed and then pop it when it is not
+ * needed anymore. Note however, that is not thread-safe if the stack
+ * is used in multi-threaded environment.
+ *
+ * EXAMPLE
+ *
+ * SilcStack stack;
+ *
+ * // Get child stack from global crypto stack
+ * stack = silc_stack_alloc(0, silc_crypto_stack());
+ * ...
+ *
+ * // Return memory back to the global crypto stack
+ * silc_stack_free(stack);
