24bcf55926 * Introduced new job_control_entry structure which, among other things,
is used instead of death_entry for team::dead_children.
* Added team::{stopped,continued}_children, which, analoguously to
  dead_children, are used to track the state of stopped/continued
  children.
* A team does have a job_control_entry, which is allocated at team
  creation time. It will be inserted into the parent's
  {stopped,continued}_children lists as the team's main thread is
  stopped/continued and removed when waitpid() retrieves the child
  state. When the team dies the entry is detached from the team and goes
  into the parent's dead_children list.
* Removed the wait_for_any field from team_dead_children. It was solely
  used to avoid deletion of the contained entries in certain situations.
  wait_for_child() (the waitpid() backend) always deletes an entry now,
  regardless of whether other threads are waiting; that's in
  accordance with the waidpid() specification. wait_for_thread() removes
  the entry only, if the caller is the parent of the respective team.
* Introduced team_set_job_control_state() which performes the job
  control entry transitions between the respective lists and wakes up
  threads waiting in wait_for_child(). It is invoked on team death and
  when the team's main thread receives job control signals.
* Reorganized wait_for_child(). It handles WCONTINUED and WUNTRACED now,
  too. Removed a block that interpreted the supplied ID as thread ID.
* Added missing parts in waitpid().

Job control starts to work, though it seems to have some glitches.

ff895459b7 * Replaced the team::dead_children::sem semaphore by a condition
variable. Due to C code including the header I had to turn it from and
  aggregated member to a pointer. I'm very close to starting to convert
  all remaining .c to .cpp files. :-/
* Got rid of the "waiters" field. It was only written, never read.
