2446 6246 d 2 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.

many minor coding style fixes
 
2071 6380 d 21 h jermar /trunk/ (c) versus (C)  
2039 6415 d 5 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
1888 6506 d 1 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1820 6553 d 18 h decky /trunk/kernel/generic/ initial security context support  
1787 6570 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6578 d 1 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6599 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1587 6607 d 0 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.
 
1585 6607 d 4 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.
