Simplify stack allocation code in child after fork
* child_info.h (CURR_CHILD_INFO_MAGIC): Update.
(child_info_fork::alloc_stack_hard_way): Drop declaration.
* dcrt0.cc (child_info_fork::alloc_stack_hard_way): Fold into
child_info_fork::alloc_stack.
(getstack): Remove.
(child_info_fork::alloc_stack): Simplify check for application-provided
stack in "hard way" code. Don't call getstack for each page, just
reallocate stack immediately as required.
