09ff55a821 BeGeistert checkin: we now have memalign() - and because of that, the
USE_WALL feature can now be used.
Started implementing a USE_CHECKING_WALLS feature, that has a kernel
daemon running that periodically checks the walls of *all* memory
allocations - does not work yet (because of some initialization order
problems).

e1e5a66bc2 BeGeistert checkin: wait_for_child() does now work as expected for any
team and process group IDs as well.
Added a ToDo item that process groups do only work well as long as
their group leader is still active.

b767f41204 BeGeistert checkin: if B_RELEASE_ALL is used, the "count" argument should be
ignored completely (so that zero and below become valid).

85fa73ff32 stdio does work, too.
Now uses waitpid() instead of wait_for_thread() - and surprise, it doesn't
work yet :)

2b6c3301f7 Forgot to put the forked team into its parent group in fork_team() - which
resulted in a nice crash on exit.

8593dcc214 Being on a kernel stack doesn't mean we didn't come from userland: we now
no longer pop %fs from the iframe in that case, too.
When we restore a custom stack, however, we'll now pop %fs from the iframe
as such strange threads may even do their own business with it.
Added some comments.

d296d770a3 %fs won't be adopted from the iframe anymore, we don't need to change it there.
We also should disable interrupts in arch_restore_fork_frame().

a7fa05a54b Since arguments may on the stack even in the kernel, load_image() now
always copies the arguments and environment arrays.
No need for the "owns_arrays" in team_arg anymore - it now always owns
them.

4578da13a4 main() now waits until interrupts are available before bringing the device drivers up.
Switched to load_image() instad of using the old team_create_team() to start "init".

bd4b903e57 Switched from the old team_create_team() to a load_image() compatible mechanism.
The path name is now always taken from the provided argument list (except for
_user_exec() which now replaces args[0] with the path argument).
The team_arg structure know nows if it must delete its arguments or not - this
also fixes a memory leak in case team_create_team() failed when invoked from
userland.
load_image() is now also exported for the kernel.

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.

48e64cd7c8 Added two experimental release_sem_etc() flags (both should stay, but they
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.

c2289a8876 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.
Removed delete_sem_etc() as it's no longer of use or available.

4609c64d48 The %fs register is used by user space TLS - it is CPU dependent, and must
not be restored from the iframe; it will be set by the scheduling code.

vm_page no longer keeps a pointer to the vm_cache_ref but to the vm_cache.

regions belong to vm_cache_ref, pages to vm_cache.

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.

81f2f81c21 If the kernel_args::cons_line field is not maintained (ie. is zero), the
console driver now clears the screen when it's initialized.
This improves the first impression of the standard boot process when
booting in text mode (which currently happens when you press "escape"
in the early boot stage).

2ef444519e Work-around for buggy device drivers: some drivers (including our current

former readv() (now read_pages()) call. This can potentially fix all sorts
of strange errors in userland :)

recreates a race condition, having it here breaks the kernel as fs_mount()

9516afb70a Added `-c' option to execute a command line. Should work, but doesn't
always do. More often than not one gets page faults. As it happens
sometimes even before anything meaty has been done at all
(e.g. in main()->init_statements()->shell_var_set_text()->
shell_value_init_text()->malloc()), I believe that's a problem not caused
by me. And I wasn't able to track it down.

4f9e4fc932 * The VFS cannot just pass the result of fs_read_dir() calls back to
Userland. It must always set the d_pdev and d_pino fields and, if the
  Entry refers to a mount point even replace d_dev and d_ino.
* Added a TODO comment to entry_ref_to_vnode(). It should take care of
  mount points, as vnode_path_to_vnode() does, I believe. Will verify
  and fix that next.

61b83cc210 * Changed my doxygen comment markers from Qt to javadoc style, still
leaving the tags Qt style though. That's a bit weird, but that's the
  way Axel likes it, and we want to keep him happy, don't we? ;-P
* The common_[path_]read_stat() now fills in st_dev and st_ino in the
  result stat structure after the FS had its go. The information is
  readily available in the VFS, so why bother the FSs. In fact devfs
  didn't (and still doesn't) fill in st_dev which gave dev_for_path()
  some head ache.
* Modified _user_open_parent_dir() to accept a NULL buffer for the
  entry name and added a doxygen comment for it.

df now works properly on Haiku (save that printf() doesn't support
floating point numbers at the moment).

86170a3cd5 * Got rid of devfs_cookie::stream. It was superfluous since one can
always also access it through the devfs_vnode. This also solves an issue
  in devfs_read() where an access of a cookie->stream would crash the
  kernel, since cookie->stream was not set in devfs_open().
* devfs_open() now doesn't fail for directories and symlinks anymore.
  That prevented BNode to work for devfs dirs and symlinks.

1dae20235b If the /..' is /' then the name of the root node should consequently be
`.'. This fixes the _kern_open_parent_dir() syscall for the root directory.

I realized, that rootfs_read_dir() doesn't return the entries `.' and `..',
unlike Be's rootfs. Shall I add those, Axel?

2829b349c6 Added a "cookie" parameter to the vfs_read|write|has_page[s]().
Added an vfs_get_cookie_from_fd() call to at least temporarily support the
cookie as in the original devfs (not sure yet how this changes).
Implemented vfs_get_file_map() which calls the corresponding FS function.
Moved vfs_get_vnode_cache() around.
vfs_get_vnode() temporarily does its job unlocked - its only to be used (safely)
from within the file cache, but this should definitely be done better.
Fixed a bug in get_vnode_name() - it did not support getting the name of
a root directory; it didn't pass the call through to the parent file system.
Fixed a bug in _user_entry_ref_to_path() which would add another "/" for
files immediately under the root (ie. "df" showed "//boot" as mount point
for the boot partition).
