88b64a6feb Big cleanup.
Now directly exports (as is, most of) the kernel thread API.
Now has user_*() functions where needed.
Moved thread_set_priority() from scheduler.c to set_thread_priority().
Renamed thread_wait_on_thread() to wait_for_thread().
user_get_thread_info() now uses user_strlcpy() instead of user_strncpy().
Fixed the snooze() implementation - it now returns B_OK where appropriate. Now all snooze()
calls will call snooze_etc().
New private call spawn_kernel_thread_etc() to replace thread_create_kernel_thread_etc().
Moved some functions around.

b848af2071 Greatly cleaned up the source.
Fixed a bug in sigaction(): it would have crashed with act/oact == NULL (which
is perfectly legal).
Now directly exports the kernel API.
Now has user_*() calls where needed.

6d8aafc66e Added comments to sys_(get|put)env() - please remove them from the kernel.
Renamed team_wait_on_team() to wait_for_team() (more BeOS-alike).
Adapted to other changes (new thread functions).

dba0db7fbe Fixed all the broken signal stuff. Now correctly calls the user_*() function,
and don't have any functionality at this place.
Added new syscall for set_thread_priority().
Some other changes due to cleanup.

51cc35a759 Cleaned up the source, rearranged some functions. Now exported functions
have the scheduler_ prefix instead of thread_.
Moved thread_set_priority() back to thread.c where it belongs to.
Added new function to remove a thread from the run queue.
Renamed run_q to gRunQueue.

dc7fb22c07 Forgot to resume the kernel_daemon thread.
Actually never unlocked the daemon's lock (always called mutex_lock() instead
of mutex_unlock()...).

457f7be6f9 Now uses the new list primitive instead of its own implementation (for linking
the vnodes of a mount structure).
Removed stubs for send_notification() and notify_listener() (they are now located
in message.c and node_monitor.c).
Added support for the node monitoring service.

(or will be) able to send out BMessages from within the kernel; currently
just prints out what should be done.

4fff689f48 Some minor updates:

a now unused variable, assignments to tss_loaded are now booleans.

20726b7fb1 _create_thread() now correctly allocates the stack with REGION_ADDR_EXACT_ADDRESS
from the USER_STACK_REGION (until B_BASE_ADDRESS is available), made it much better
readable. It now grows from the lower USER_STACK_REGION up to the start of the main
thread's stack location.
Calls arch_thread_tls_init() and accounts for the TLS area in the stack region.
Added some comments, some cleanups.

2a6fbb7f88 Removed some hard-coded values with definitions (mostly USER_x_SEG in arch_x86.S,
and TSS_BASE_SEGMENT in i386_set_tss_and_kstack() (thanks Daniel for pointing this
out)).
Added a arch_thread_init_tls() function which fills the reserved slots - the find_thread()
inline asm in OS.h is finally working.
Added some more comments, resolved the ToDo items from last time :-)
arch_thread_context_switch() now calls set_tls_context() at the correct location.
arch_thread_enter_uspace() now calls set_tls_context() as there is no context
switch in this case for the current thread after TLS has been set up, and it
now gets a pointer to the thread structure directly, and calculates the user
stack top itself, rather than the callee.

19321ae5a8 Temporarily removed arch_selector.c from the build - it's currently not used
at all, and assumes a fixed and wrong number of preallocated GDT entries.

Implemented TLS: there is one GDT entry per CPU. If a context switch happens,
the FS register of the new thread is set to the matching GDT, and the GDT is
changed so that it points to the current thread's TLS storage area.
This area currently resides unsafely at the bottom of the user stack - for
some reason I could not figure out, it doesn't even work correctly most of
the time (it segfaults when accessing a slot via FS). I've added a ToDo item
explaining the situation - hopefully I have more ideas when I slept a bit more...

The GDT is now no longer static in arch_cpu.c and has been renamed from gdt to
gGDT. It's now also referenced in arch_thread.c, and it would make sense for
arch_selector.c to use it as well (instead of another local copy).
arch_cpu_init2() now uses the set_tss_descriptor() inline function and the
TSS_BASE_SEGMENT macro to set up the TSS section. It now also sets up the
TLS segment descriptors (as TSS, one entry per CPU).

Since I removed desc_table from the headers (the GDT is now a (segment_descriptor *)),
I added it locally to arch_int.c.
i386_enter_uspace() now don't set the FS register to 0x23 anymore, since it's
now already set correctly at the end of arch_thread_context_switch().

Some clean-ups.
