Unify node handling functions:
* node_alloc() for mdoc and man_node_alloc() -> roff_node_alloc() * node_append() for mdoc and man_node_append() -> roff_node_append() * mdoc_head_alloc() and man_head_alloc() -> roff_head_alloc() * mdoc_body_alloc() and man_body_alloc() -> roff_body_alloc() * mdoc_node_unlink() and man_node_unlink() -> roff_node_unlink() * mdoc_node_free() and man_node_free() -> roff_node_free() * mdoc_node_delete() and man_node_delete() -> roff_node_delete() Minus 130 lines of code, no functional change.
