JoinMe -> Lingering |

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. |

Fix the problem with sys_thread_create() by splitting the create and attach functionality of
thread_create(). Now it is possible to specify a flag that will cause thread_create() to only allocate and
initialize the thread structure. A call to thread_attach() will make the thread visible to the system.
This arrangement makes it easier to undo creation of a thread in case of a failure in sys_thread_create(). |

Revert thread_interrupt_sleep() to waitq_interrupt_sleep().
I'd prefer that this, IMO, waitq related stuff stays together. |

Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.
A lot of formatting and indentation fixes. |

Framework for task_kill().
Some pieces (e.g. implementation of ktask_cleanup() kernel thread and
task_destroy() function) are missing.
Changed locking order for task lock, threads_lock and thread lock from
threads_lock, thread lock, task lock to task lock, threads_lock, thread lock. |

Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.

Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided. |

Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64. |
