Rework DSO API conditions and configuration option

'no-dso' is meaningless, as it doesn't get any macro defined.
Therefore, we remove all checks of OPENSSL_NO_DSO.  However, there may
be some odd platforms with no DSO scheme.  For those, we generate the
internal macro DSO_NONE aand use it.

trace: rename the default trace category from 'ANY' to 'ALL'

trace: apps/openssl: print the correct category name

Previously, if the openssl application was run with OPENSSL_TRACE=any,
all trace output would just show 'ANY' as the category name, which was
not very useful. To get the correct category name printed in the trace
output, the openssl application now registers separate channels for
each category.

The trace API is unchanged, it is still possible for an application to
register a single channel for the 'ANY' category to see all outputt,
if it does not need this level of detail.

trace: don't pretend success if it's not enabled

Partially reverts d33d76168fb7 Don't fail when tracing is disabled

Commit d33d76168fb7 fixed the problem that the initialization of
libcrypto failed when tracing was disabled, because the unoperational
ossl_trace_init() function returned a failure code. The problem was
fixed by changing its return value from failure to success.

As part of the fix the return values of other unimplemented trace API
functions (like OSSL_trace_set_channel(),OSSL_trace_set_callback())
was changed from failure to success, too. This change was not necessary
and is a bit problematic IMHO, because nobody expects an unimplemented
function to pretend it succeeded.

It's the application's duty to handle the case correctly when the trace
API is not enabled (i.e., OPENSSL_NO_TRACE is defined), not the API's job
to pretend success just to prevent the application from failing.

Increase rounds of Miller-Rabin testing DH_check

DH_check is used to test the validity of Diffie-Hellman parameter sets (p, q, g). Among the tests performed are primality tests on p and q, for this BN_is_prime_ex is called with the rounds of Miller-Rabin set as default. This will therefore use the average case error estimates derived from the function BN_prime_checks_for_size based on the bit size of the number tested.

However, these bounds are only accurate on testing random input. Within this testing scenario, where we are checking the validity of a DH parameter set, we can not assert that these parameters are randomly generated. Thus we must treat them as if they are adversarial in nature and increase the rounds of Miller-Rabin performed.

Generally, each round of Miller-Rabin can declare a composite number prime with probability at most (1/4), thus 64 rounds is sufficient in thwarting known generation techniques (even in safe prime settings - see https://eprint.iacr.org/2019/032 for full analysis). The choice of 64 rounds is also consistent with SRP_NUMBER_ITERATIONS_FOR_PRIME 64 as used in srp_Verify_N_and_g in openssl/apps/s_client.c.

Replumbing: Add a mechanism to pre-populate the provider store

OpenSSL will come with a set of well known providers, some of which
need to be accessible from the start.  These are typically built in
providers, or providers that will work as fallbacks.

We do this when creating a new provider store, which means that this
will happen in every library context, regardless of if it's the global
default one, or an explicitely created one.

We keep the data about the known providers we want to make accessible
this way in crypto/provider_predefined.h, which may become generated.
For now, though, we make it simple and edited manually.

apps/speed.c: properly address NO_EC2M on systems without SIGALRM

The ecdh_c array is allocated of the same size as ecdh_choices,
whose size depends on whether the support for binary curves is enabled
or not.  (The same goes for ecdsa_c).
On systems without SIGALRM, ecdh_c is indexed by predefined constants
intended for representing the index of the ciphers in the ecdh_choices
array.
However, in case of NO_EC2M some of the #defined constants won't match
and would actually access the ecdh_c out-of-bounds.

Use enum instead of a macro to define the curve indexes so they're
within the bounds of the ecdh_c array.

apps/speed.c: skip binary curves when compiling with OPENSSL_NO_EC2M

openssl speed doesn't take into account that the library could be
compiled without the support for the binary curves and happily uses
them, which results in EC_GROUP_new_by_curve_name() errors.

Fix no-posix-io

'openssl pkeyutl' uses stat() to determine the file size when signing using
Ed25519/Ed448, and this was guarded with OPENSSL_NO_POSIX_IO.

It is however arguable if stat() is a POSIX IO function, considering
that it doesn't use file descriptors, and even more so since we use
stat() elsewhere without that guard.

This will allow test/recipes/20-test_pkeyutl.t to be able to do its
