exit status of (non-main) threads of a team. Fixes bug #1644.

* Removed old port test code, it doesn't belong there.
* Cleanup.

team as well. Otherwise the children would later try to remove them from
a list they weren't in.

group ID with the session and let the terminal update them.
* Added an "orphaned" flag to the process_group structure and code to
maintain it.
* Handle the death of a controlling process correctly: The
foreground process group gets a SIGHUP and all newly-orphaned process
groups containing at least one stopped processes are sent
SIGHUP+SIGCONT.
* The tty handles the O_NOCTTY flag correctly, now.
* The tty handles reads/writes from processes from other sessions
correctly, now.
* Handle tcsetpgrp() from background processes correctly.

shadowing variables).
* Resolved TODO: We wake up the parent if waiting in wait_for_child()
now, if the process group changes.
* Added another TODO: setpgid() is supposed to fail on a child after
it has executed exec*().

blocked and no other child status is available.
* Respect SA_NOCLDWAIT and ignored SIGCHLD in waitpid(): Unless a child
status is available immediately, the thread shall block until all
children are gone.

space - but they were released upon deletion. It's probably not really
needed, but now all reserved areas also grab a reference to their address
space.
* Rearranged team tear down to be a bit more sane: the I/O context is removed
first (where semaphores/areas/ports/whatever might still be used), and the
address space is deleted last.
* delete_area() can now remove its address space reference again (due to the
two changes above), and therefore fixes bug #1374.
* cleaned up vm_address_space.c a bit (no functional change there, though).

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.

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.
