Quite a few adaptations are needed, most prominently the added code
to allow provider based MACs.
As part of this, all the old information functions are gone, except
for EVP_MAC_name(). Some of them will reappear later, for example
EVP_MAC_do_all() in some form.
MACs by EVP_PKEY was particularly difficult to deal with, as they
need to allocate and deallocate EVP_MAC_CTXs "under the hood", and
thereby implicitly fetch the corresponding EVP_MAC. This means that
EVP_MACs can't be constant in a EVP_MAC_CTX, as their reference count
may need to be incremented and decremented as part of the allocation
or deallocation of the EVP_MAC_CTX. It may be that other provider
based EVP operation types may need to be handled in a similar manner.

1. In addition to overriding the default application name,
one can now also override the configuration file name
and flags passed to CONF_modules_load_file().
2. By default we still keep going when configuration file
processing fails. But, applications that want to be strict
about initialization errors can now make explicit flag
choices via non-null OPENSSL_INIT_SETTINGS that omit the
CONF_MFLAGS_IGNORE_RETURN_CODES flag (which had so far been
both undocumented and unused).
3. In OPENSSL_init_ssl() do not request OPENSSL_INIT_LOAD_CONFIG
if the options already include OPENSSL_INIT_NO_LOAD_CONFIG.
4. Don't set up atexit() handlers when called with INIT_BASE_ONLY.

We have a number of instances where there are multiple "init" functions for
a single CRYPTO_ONCE variable, e.g. to load config automatically or to not
load config automatically. Unfortunately the RUN_ONCE mechanism was not
correctly giving the right return value where an alternative init function
was being used.

The GOST engine needs to be loaded before we initialise libssl. Otherwise
the GOST ciphersuites are not enabled. However the SSL conf module must
be loaded before we initialise libcrypto. Otherwise we will fail to read
the SSL config from a config file properly.
Another problem is that an application may make use of both libcrypto and
libssl. If it performs libcrypto stuff first and OPENSSL_init_crypto()
is called and loads a config file it will fail if that config file has
any libssl stuff in it.
This commit separates out the loading of the SSL conf module from the
interpretation of its contents. The loading piece doesn't know anything
about SSL so this can be moved to libcrypto. The interpretation of what it
means remains in libssl. This means we can load the SSL conf data before
libssl is there and interpret it when it later becomes available.

IF OPENSSL_init_ssl() is called with the option flag
OPENSSL_INIT_LOAD_CONFIG, any SSL config will be handled wrongly
(i.e. there will be an attempt to load libssl_conf.so or whatever
corresponds to that on non-Unix platforms). Therefore, at least
SSL_add_ssl_module() MUST be called before OPENSSL_init_crypto() is
called. The base ssl init does that, plus adds all kinds of ciphers
and digests, which is harmless.

There is a preference for suffixes to indicate that a function is internal
rather than prefixes. Note: the suffix is only required to disambiguate
internal functions and public symbols with the same name (but different

If init failed we'd like to set an error code to indicate that. But if
init failed then when the error system tries to load its strings its going
to fail again. We could get into an infinite loop. Therefore we just set
a single error the first time around. After that no error is set.

This commit provides the basis and core code for an auto initialisation
and deinitialisation framework for libcrypto and libssl. The intention is
to remove the need (in many circumstances) to call explicit initialise and
deinitialise functions. Explicit initialisation will still be an option,
and if non-default initialisation is needed then it will be required.
Similarly for de-initialisation (although this will be a lot easier since
it will bring all de-initialisation into a single function).
