Richard Levitte e077455e9e Stop raising ERR_R_MALLOC_FAILURE in most places
Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.

There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called.  Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.

Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.

Tomas Mraz d840f07bcd Avoid crashing if CONF_modules_unload() is called after OPENSSL_cleanup()
Although this is basically an incorrect API call it was not crashing
before and it might happen inadvertently if CONF_modules_unload()
is called from a destructor for example.

Matt Caswell 697d0b5ba1 CONF_modules_unload should fail if CONF_modules_finish fails
The module_list_lock is used by CONF_modules_unload(). That function relies
on the RUN_ONCE in CONF_modules_finish() to initialise that lock. However
if the RUN_ONCE fails that failure is not propagated to
CONF_modules_unload() and so it erroneously tries to use the lock anyway.

Matt Caswell b9b2135d22 Don't clear the whole error stack when loading engines
Loading the various built-in engines was unconditionally clearing the
whole error stack. During config file processing processing a .include
directive which fails results in errors being added to the stack - but
we carry on anyway. These errors were then later being removed by the
engine loading code, meaning that problems with the .include directive
never get shown.

Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix,
e.g., OSSL_CALLBACK, OSSL_PARAM, OSSL_ALGORITHM, OSSL_SERIALIZER.

The OPENSSL_CTX type stands out a little by using a different prefix.
For consistency reasons, this type is renamed to OSSL_LIB_CTX.

Shane Lontis 22e27978b2 Add support for passing the libctx to the config loader
The self tests for the fips module are triggered on startup and they need to know the
core's libctx in order to function correctly. As the provider can be autoloaded via configuration
it then needs to propagate the callers libctx down to the provider via the config load.

Note that OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CONFIG, ..) is still called, but will only load the default
configuration if the OPENSSL_CONF environment variable is set.

Viktor Dukhovni df1f538f28 More configurable crypto and ssl library initialization
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.
