Axel Dörfler 2e27874523 * wait_for_child() now behaves correctly when waiting for children of a specific
process group. This fixes bug #996.
* As a result, the process group stuff and wait_for_child() got much simpler;
  get_death_entry() and update_wait_for_any() could go away completely.
* If a team goes away, all of its children are now "reparented" to the kernel team,
  instead of the team's parent - this follows common implementations (and POSIX if
  I understand it correctly), but not BeOS anymore. The OpenGroup Base says this
  about this topic: "If a parent process terminates without waiting for all of its
  child processes to terminate, the remaining child processes shall be assigned a
  new parent process ID corresponding to an implementation-defined system process."
* We wait too long in wait_test_4 which at least puts us on par with Linux; see
  comment in _user_setpgid().
