* 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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22088 a95241bf-73f2-0310-859d-f6bbb57e9c96
