Fix EVP_Cipher() for provided cipher implementations

EVP_Cipher() would return whatever ctx->cipher->ccipher() returned
with no regard for historical semantics.

We change this to first look if there is a ctx->cipher->ccipher(), and
in that case we treat the implementation as one with a custom cipher,
and "translate" it's return value like this: 0 => -1, 1 => outl, where
|outl| is the output length.

If there is no ctx->cipher->ccipher, we treat the implementation as
one without a custom cipher, call ctx->cipher->cupdate or
ctx->cipher->cfinal depending on input, and return whatever they
return (0 or 1).

Furthermore, we add a small hack in EVP_CIPHER_flags() to check if the
cipher is a provided one, and add EVP_CIPH_FLAG_CUSTOM_CIPHER to the
flags to be returned if there is a cipher->ccipher.  That way,
provided implementations never have to set that flag themselves, all
they need to do is to include a OSSL_FUNC_CIPHER_CIPHER function.

Prior to OpenSSL 3.0 EVP_Digest[Sign|Verify|Update were just macros for
EVP_DigestUpdate. They are now separate functions. Unfortunately some
code assumes that EVP_Digest[Sign|Verify]Update is interchangeable with
EVP_DigestUpdate. For example the dgst app uses an MD bio which always
calls EVP_DigestUpdate(). However the dgst app supports signing instead

Rework how our providers are built

We put almost everything in these internal static libraries:

libcommon               Block building code that can be used by all
                        our implementations, legacy and non-legacy
                        alike.
libimplementations      All non-legacy algorithm implementations and
                        only them.  All the code that ends up here is
                        agnostic to the definitions of FIPS_MODE.
liblegacy               All legacy implementations.

libnonfips              Support code for the algorithm implementations.
                        Built with FIPS_MODE undefined.  Any code that
                        checks that FIPS_MODE isn't defined must end
                        up in this library.
libfips                 Support code for the algorithm implementations.
                        Built with FIPS_MODE defined.  Any code that
                        checks that FIPS_MODE is defined must end up
                        in this library.

The FIPS provider module is built from providers/fips/*.c and linked
with libimplementations, libcommon and libfips.

The Legacy provider module is built from providers/legacy/*.c and
linked with liblegacy, libcommon and libcrypto.
If module building is disabled, the object files from liblegacy and
libcommon are added to libcrypto and the Legacy provider becomes a
built-in provider.

The Default provider module is built-in, so it ends up being linked
with libimplementations, libcommon and libnonfips.  For libcrypto in
form of static library, the object files from those other libraries
are simply being added to libcrypto.

Configurations/common.tmpl: Rework dependency resolution

The dependency resolution is made uniquely to resolve proper library
order when linking a program, a module or a shared library.

resolvedepends() did a little too much at once, so it's now reduced to
only collect dependencies (and is renamed to collectdepends()), while
a new function, expanddepends(), expands a list of dependency to
insure that dependent libraries are present after depending libraries,
and finally there is reducedepends() which removes unnecessary
duplicates, leaving only the last one.

resolvedepends() is now a simple utility routine that calls the three
mentioned above in correct order.

As part of this, we implement weak dependencies through the 'weak'
build.info attribute.  This is meant to cause a specific order between
libraries without requiring that they are all present.

Adapt EVP_CIPHER_{param_to_asn1,asn1_to_param} for use with provider.

So far, these two funtions have depended on legacy EVP_CIPHER
implementations to be able to do their work.  This change adapts them
to work with provided implementations as well, in one of two possible
ways:

1.  If the implementation's set_asn1_parameters or get_asn1_parameters
    function pointers are non-NULL, this is a legacy implementation,
    and that function is called.
2.  Otherwise, if the cipher doesn't have EVP_CIPH_FLAG_CUSTOM_ASN1
    set, the default AlgorithmIdentifier parameter code in libcrypto
    is executed.
3.  Otherwise, if the cipher is a provided implementation, the ASN1
    type structure is converted to a DER blob which is then passed to
    the implementation as a parameter (param_to_asn1) or the DER blob
    is retrieved from the implementation as a parameter and converted
    locally to a ASN1_TYPE (asn1_to_param).

With this, the old flag EVP_CIPH_FLAG_DEFAULT_ASN1 has become
irrelevant and is simply ignored.

Furthermore, for TYPE used as a placeholder for types and correponding
part of function names, we extrapolate that it's both a type and a
variable, and should therefore be bold (typical for types and function
names) and italic (typical for variables).  POD processors don'e know
this, so we have to help them along.  Therefore:

   SPARSE_ARRAY_OF(TYPE)        => B<SPARSE_ARRAY_OF>(B<I<TYPE>>)
   ossl_sa_TYPE_num()           => B<ossl_sa_I<TYPE>_num>()
   TYPE                         => B<I<TYPE>>

There are some other less typical uses where one simply has to give
formatting some extra though.
