commit 254217a4a0c9e64869495447a0e6bdc2323d4cd1

    Clarify the int param getter documentation
    
    OSSL_PARAMs that are of type OSSL_PARAM_INTEGER or
    OSSL_PARAM_UNSIGNED_INTEGER can be obtained using any of the functions
    EVP_PKEY_get_int_param(), EVP_PKEY_get_size_t_param() or
    EVP_PKEY_get_bn_param(). The former two will fail if the parameter is too
    large to fit into the C variable. We clarify this in the documentation.

+An B<OSSL_PARAM> of type B<OSSL_PARAM_INTEGER> or
+B<OSSL_PARAM_UNSIGNED_INTEGER> is of arbitrary length. Such a parameter can be
+obtained using any of the functions EVP_PKEY_get_int_param(),
+EVP_PKEY_get_size_t_param() or EVP_PKEY_get_bn_param(). Attempting to
+obtain an integer value that does not fit into a native C B<int> type will cause
+EVP_PKEY_get_int_param() to fail. Similarly attempting to obtain an integer
+value that is negative or does not fit into a native C B<size_t> type using
+EVP_PKEY_get_size_t_param() will also fail.

 EVP_PKEY_get_int_param() retrieves a key I<pkey> integer value I<*out>
 associated with a name of I<key_name>.
