A fuller implementation of PARAMS_TEMPLATE as per #9266 but renamed.
This introduces a statis data type which can be used to constructor a
description of a parameter array.  It can then be converted into a OSSL_PARAM
array and the allocated storage freed by a single call to OPENSSL_free.

=head1 DESCRIPTION
A collection of utility functions that simplify the creation of OSSL_PARAM
arrays. The B<TYPE> names are as per L<OSSL_PARAM_int(3)>.
ossl_param_build_init() initialises the OSSL_PARAM_BLD structure so that values
can be added.
Any existing values are cleared.
ossl_param_build_to_param() converts a built up OSSL_PARAM_BLD structure
B<bld> into an allocated OSSL_PARAM array.
The pointer referenced by the B<secure> argument is set to point to an
allocated block of secure memory if required and to NULL it not.
The OSSL_PARAM array and all associated storage can be freed by calling
OPENSSL_free() with the functions return value and OPENSSL_secure_free()
with the pointer referenced by B<secure>.
ossl_param_build_to_param_ex() behaves like ossl_param_build_to_param(), except that
no additional memory is allocated.
An OSSL_PARAM array of at least B<param_n> elements is passed in as B<params>.
The auxiliary storage for the parameters is a block of memory pointed to
by B<data> of at least B<data_n> bytes in size.
If required, secure memory for private BIGNUMs should be pointed to by
B<secure> of at least B<secure_n> bytes in size.
ossl_param_build_push_TYPE() are a series of functions which will create
OSSL_PARAM objects of the specified size and correct type for the B<val>
argument.
B<val> is stored by value and an expression or auto variable can be used.
ossl_param_build_push_BN() is a function that will create an OSSL_PARAM object
that holds the specified BIGNUM B<bn>.
If B<bn> is marked as being securely allocated, the secure flag is
set in the OSSL_PARAM_BLD structure.
The B<bn> argument is stored by reference and the underlying BIGNUM object
must exist until after ossl_param_build_to_param() has been called.
ossl_param_build_push_utf8_string() is a function that will create an OSSL_PARAM
object that references the UTF8 string specified by B<buf>.
If the length of the string, B<bsize>, is zero then it will be calculated.
The string that B<buf> points to is stored by reference and must remain in
scope until after ossl_param_build_to_param() has been called.
ossl_param_build_push_octet_string() is a function that will create an OSSL_PARAM
object that references the octet string specified by B<buf> and <bsize>.
The memory that B<buf> points to is stored by reference and must remain in
scope until after ossl_param_build_to_param() has been called.
ossl_param_build_push_utf8_ptr() is a function that will create an OSSL_PARAM
object that references the UTF8 string specified by B<buf>.
If the length of the string, B<bsize>, is zero then it will be calculated.
The string B<buf> points to is stored by reference and must remain in
scope until the OSSL_PARAM array is freed.
ossl_param_build_push_octet_ptr() is a function that will create an OSSL_PARAM
object that references the octet string specified by B<buf>.
The memory B<buf> points to is stored by reference and must remain in
scope until the OSSL_PARAM array is freed.
=head1 RETURN VALUES
ossl_param_build_to_param() and ossl_param_bld_to_param_ex() return the
allocated OSSL_PARAM array, or NULL on error.
All of the ossl_param_build_push_TYPE functions return 1 on success and 0
on error.
=head1 NOTES
The constant B<OSSL_PARAM_BLD_MAX> specifies the maximum number of parameters
that can be added.
Exceeding this will result in the push functions returning errors.
The structure B<OSSL_PARAM_BLD> should be considered opaque and subject to
change between versions.
=head1 EXAMPLES
Both examples creating an OSSL_PARAM array that contains an RSA key.
For both, the predefined key variables are:
BIGNUM *p, *q; /* both prime */
BIGNUM *n; /* = p * q */
unsigned int e; /* exponent, usually 65537 */
BIGNUM *d; /* e^-1 */
=head2 Example 1
This example shows how to create an OSSL_PARAM array that contains an RSA
private key.
OSSL_PARAM_BLD bld;
OSSL_PARAM *params;
void *secure;
ossl_param_build_init(&bld, &secure);
if (!ossl_param_build_push_BN(&bld, "p", p)
|| !ossl_param_build_push_BN(&bld, "q", q)
|| !ossl_param_build_push_uint(&bld, "e", e)
|| !ossl_param_build_push_BN(&bld, "n", n)
|| !ossl_param_build_push_BN(&bld, "d", d)
|| (params = ossl_param_build_to_param(&bld)) == NULL)
goto err;
