Core: ngx_conf_set_keyval_slot() now accepts NGX_CONF_UNSET_PTR.

With this change, it is now possible to use ngx_conf_merge_ptr_value()
to merge keyval arrays.  This change actually follows much earlier
changes in ngx_conf_merge_ptr_value() and ngx_conf_set_str_array_slot()
in 1452:cd586e963db0 (0.6.10) and 1701:40d004d95d88 (0.6.22).

To preserve compatibility with existing 3rd party modules, both NULL
and NGX_CONF_UNSET_PTR are accepted for now.
