The code has been modularized so that it can be shared by algorithms. A fixed size IV is now used instead of being allocated. The IV is not set into the low level struct now until the update (it uses an iv_state for this purpose). Hardware specific methods have been added to a PROV_GCM_HW object. The S390 code has been changed to just contain methods that can be accessed in a modular way. There are equivalent generic methods also for the other platforms.

Adding new libraries
--------------------
When adding a new sub-library to OpenSSL, assign it a library number
ERR_LIB_XXX, define a macro XXXerr() (both in err.h), add its
name to ERR_str_libraries[] (in crypto/err/err.c), and add
ERR_load_XXX_strings() to the ERR_load_crypto_strings() function
(in crypto/err/err_all.c). Finally, add an entry:
L XXX xxx.h xxx_err.c
to crypto/err/openssl.ec, and add xxx_err.c to the Makefile.
Running make errors will then generate a file xxx_err.c, and
add all error codes used in the library to xxx.h.
Additionally the library include file must have a certain form.
Typically it will initially look like this:
#ifndef HEADER_XXX_H
#define HEADER_XXX_H
#ifdef __cplusplus
extern "C" {
#endif
/* Include files */
#include <openssl/bio.h>
#include <openssl/x509.h>
/* Macros, structures and function prototypes */
/* BEGIN ERROR CODES */
The BEGIN ERROR CODES sequence is used by the error code
generation script as the point to place new error codes, any text
after this point will be overwritten when make errors is run.
The closing #endif etc will be automatically added by the script.
The generated C error code file xxx_err.c will load the header
files stdio.h, openssl/err.h and openssl/xxx.h so the
header file must load any additional header files containing any
definitions it uses.
