process ID (in the current session).
get_death_entry() could call free() with interrupts disabled; now follows
the same mechanism as chosen with the groups (ie. it returns a pointer
to a death_entry to be freed by the calling function).

the specified process group (by passing in a negative pid, as in BeOS).

- we now have a working process group/session model. Implemented related syscalls
and the kernel backend, some POSIX process functions are now available in the
kernel as well.
- dying teams now monitor their exitus by leaving death_entry structures in
their parent team.
- Implemented wait_for_child() for pid == -1 and pid > 0; IOW waiting for process
groups is missing yet. Hasn't yet been tested intensively.

Changed team_remove_team() to support process groups.
Added new prototype for team_delete_process_group().

Moved the dead_children stuff into a sub-structure.

API modifications for ServerApp to support PortLink messages sent via an area
Added a RAM-based PortLink message reader to handle reading from an area

may be renamed):
- B_RELEASE_ALL: the semaphore count is set to 0, all waiting threads are released
(the "count" argument of release_etc_sem() is ignored then)
- B_RELEASE_IF_WAITING_ONLY: the semaphore count is only decreased if there
are any waiting threads; ie. the semaphore is signaled
Together, they will make the pthread_cond_*() functions easy to implement, and
they come in handy at other places, too.
Removed release_threads variable in release_sem_etc(), as it was useless.

Also removed syscall for that function (shouldn't have been there in the
first place, anyway).

no longer abuse the semaphore mechanism to carry an extra status value,
instead, wait_for_thread() registers a death_entry with the thread that
will be filled upon exit.
Removed delete_sem_etc() as it's no longer of use or available.

Changed the way a dying thread propagates its exit status and reason: we
no longer abuse the semaphore mechanism to carry an extra status value,
instead, wait_for_thread() registers a death_entry with the thread that
will be filled upon exit.

Fixes _user_wait_for_thread() which returned an invalid return code in case
of error.
Some minor cosmetics.

This is only of concern on SMP machines and could prevent TLS from working.
