Add OSSL_PARAM_dup() and OSSL_PARAM_merge().

Browse Source 
These functions are prerequisites for implementing EVP_PKEY_todata().

OSSL_PARAM_dup() is required to make a deep copy of the exported
params (since the provider export() uses a OSSL_PARAM_BLD which throws away the
data after the call), and then use OSSL_PARAM_merge() to add some additional params
that can be passed to the EVP_PKEY_todata().

=head1 NAME
OSSL_PARAM_dup, OSSL_PARAM_merge, OSSL_PARAM_free
- OSSL_PARAM array copy functions
=head1 SYNOPSIS
#include <openssl/params.h>
OSSL_PARAM *OSSL_PARAM_dup(const OSSL_PARAM *params);
OSSL_PARAM *OSSL_PARAM_merge(const OSSL_PARAM *params, const OSSL_PARAM *params1);
void OSSL_PARAM_free(OSSL_PARAM *params);
=head1 DESCRIPTION
Algorithm parameters can be exported/imported from/to providers using arrays of
B<OSSL_PARAM>. The following utility functions allow the parameters to be
duplicated and merged with other B<OSSL_PARAM> to assist in this process.
OSSL_PARAM_dup() duplicates the parameter array I<params>. This function does a
deep copy of the data.
OSSL_PARAM_merge() merges the parameter arrays I<params> and I<params1> into a
new parameter array. If I<params> and I<params1> contain values with the same
'key' then the value from I<params1> will replace the I<param> value. This
function does a shallow copy of the parameters. Either I<params> or I<params1>
may be NULL. The behaviour of the merge is unpredictable if I<params> and
I<params1> contain the same key, and there are multiple entries within either
array that have the same key.
OSSL_PARAM_free() frees the parameter array I<params> that was created using
OSSL_PARAM_dup(), OSSL_PARAM_merge() or OSSL_PARAM_BLD_to_param().
=head1 RETURN VALUES
The functions OSSL_PARAM_dup() and OSSL_PARAM_merge() return a newly allocated
B<OSSL_PARAM> array, or NULL if there was an error. If both parameters are NULL
then NULL is returned.
=head1 SEE ALSO
L<OSSL_PARAM(3)>, L<OSSL_PARAM_BLD(3)>
=head1 HISTORY
The functions were added in OpenSSL 3.0.
