4711148ca9 wait_for_child() can now also wait on children in the current or any other
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).

6a70123a9d Big update, but everything is related:
- 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.

fdbd1b5d7b fork_team() is working now! It might not be 100% complete (signal handling),
but the kernel part seems to work good enough for now.

71eeb427c3 Implemented team_get_address_space() which gets you a pointer to the
team's address space - for internal use, anyway.
Added a ToDo: item to exec_team() to remind me of alarms and signals.
Started implementing fork_team() based on team_create_team() - it's not
completed (or even works), though.

da504d877d Removed team::_aspace_id since it already has a direct pointer to it.
Changed the way a vm_address_space is deleted: instead of having to explicitly
call vm_delete_aspace(), the last vm_put_aspace() will remove it.

acfca1a3f5 We now have a working exec_team() function (the backend of the exec() function family)!
Should be tested and verified more intensively, though.
Moved the creation, initialization, and deletion of the team_arg structure out of
team_create_team(); it's now also used by exec_team().
Renamed kfree_strings_array() to free_strings_array().
Renamed the fields of the team_arg structure to be more in sync with the names used
at other places.
Fixed the routine that copied the environment/arguments into the userland space.
Improved and fixed the user_copy_strings_array() function.

0f5095f9f9 Now uses thread::user_stack_size instead of STACK_SIZE. This also fixes a
potential bug if MAIN_STACK_SIZE and STACK_SIZE would have been different.

f57dcf3200 Several follow-up changes required by the changes either to the VFS
syscalls or to the syscall mechanism (which exposed naming and parameter
inconsistencies).

6f09e38dea team_create_team2() no longer panics if it couldn't create the userland
stack - it just fails now (since create_area() currently panics when it
fails, this is a cosmetic change anyway :-)).
Now correctly cleans up in case elf_load_user_image() fails.

b918b5035f Bye, bye elf_lookup_symbol(), hello get_image_symbol().
Also renamed elf_load_kspace() to load_kernel_add_on(), and friends.
The new unload_kernel_add_on() now has an image_id as parameter, no longer
a path (like the former elf_unload_kspace()).
Fixed missign file system unload.

Cleaned up the headers.

08b73e5905 Added another argument parameter for the thread creation code. Helps
implementing a more efficient on_exit_thread().
Note, this extra parameter is currently only used for user space code,
not yet in the kernel; thus on_exit_thread() is not available in the kernel.
