level argument.

* Added "mode" parameter to set_paranoia_check(), which specifies
whether the check is supposed to already exist/not exist yet. This
allows for, as it turns out, very useful additional tests. Added
{ADD,UPDATE}_PARANOIA_CHECK macros that imply the used "mode"
parameter.
* PARANOIA_SLOT_COUNT was accidentally redefined in the source file.
* Fixed remove_paranoia_check(). It didn't remove anything.

* Added capture_tracing_stack_trace() which allocates space in the
tracing buffer and captures the stack trace according to the given
parameters.
* Added TraceOutput::PrintStackTrace() to print a stack trace thus
created.
* Added TraceEntry::DumpStackTrace() callback which is supposed to print
a stack trace for the entry, if it can do that.
* Added "--stacktrace" switch to the "traced" command, which causes the
stack traces for all entries that have one to be printed as well.

principle /dev/pt/ is obsolete now, but I guess we keep it around for
compatibility with BeOS. Though there shouldn't be many applications

thread_block(), thread_unblock(),...) that allow a thread to wait for
something without needing a semaphore or condition variable. It can
simply block and another thread can unblock it. Supports timeouts and
interrupting. Both semaphores and condition variables use this
common mechanism, now.
* Semaphores:
- Some simplifications due to the thread blocking mechanism.
- Changed locking order to sem -> thread. It was the other way around
before and when introducing the wait_for_objects() support I had
also introduced a situation where the locking was reverse, which
could potentially cause a dead lock on SMP systems.
- Instead of queueing thread structures, a semaphore queues
queued_thread entries now, which are created on the stack. The
thread::sem structure could thus be removed.
- Added sem_entry::net_count, which is sem_entry::count plus the
acquisition count of all waiting threads. This number is needed in
remove_thread_from_sem() and instead of computing it there we
maintain it.
- Fixed remove_thread_from_sem(). It would not unblock threads, if
the sem count was <= 0.
- Made sem::last_acquirer unconditional. It is actually needed for
sem_info::latest_holder. Fixed fill_sem_info() accordingly.
- Added some optional tracing output, though only via ktrace_printf().
* Condition variables:
- Could be simplified significantly through the use of the thread
blocking mechanism. Removed a good deal of unnecessary code.
- Moved the ConditionVariableEntry "flags" parameter from Wait() to
Add(), and adjusted all places where condition variables are used
accordingly.
* snooze() uses thread_block_with_timeout() instead of a semaphore.
* Simplified thread interrupting in the signal and user debugger code.
Instead of separate functions for threads waiting on a semaphore or
condititon variable, we only have a single thread_interrupt(), now.

- If the hook of the timer we're cancelling is currently being
executed, we do now wait till it is finished. This is how the BeBook
specifies the function to behave.
- Periodic timers would not be cancelled, if their hook was being
invoked at the same time, since they weren't in the queue during
that time.
- Since we know the CPU on which the timer is scheduled (timer::cpu),
we don't have to look through any other CPU queue to find it.
- Fixed the return value. It should report whether the timer had
already fired, and was not always doing that.
* Added private add_timer() flag B_TIMER_ACQUIRE_THREAD_LOCK. It causes
the thread spinlock to be acquired before the event hook is called.
cancel_timer() doesn't wait for timers with the flag set. Instead we
check in the timer interrupt function after acquiring the thread
spinlock whether the timer was cancelled in the meantime. Calling
cancel_timer() with the thread spinlock being held does thus avoid any
race conditions and won't deadlock, if the event hook needs to acquire
the thread spinlock, too. This feature proves handy for some kernel
internal needs.
* The scheduler uses a B_TIMER_ACQUIRE_THREAD_LOCK timer now and
cancel_timer() instead of the no longer needed
_local_timer_cancel_event().

additional filtering. This way other commands can print tracing output
with special filtering.

condition (child dead, stopped, continued) occurs. These events are
relatively rare anyway, and it simplifies the code.

former userland server driver (that I also removed - it can always be
resurrected from SVN if needed).

and defines the macros needed by them.
* Renamed syscall sys_vm_map_file() to _kern_map_file() and changed the
path to an FD parameter. Changed vm_map_file() accordingly and
adjusted the kernel ELF loader and the runtime loader.
* Added syscall _kern_unmap_memory().
* Added bool unmapAddressRange parameter to vm_create_anonymous_area()
and map_backing_store(). If true and the address specification is
B_EXACT_ADDRESS, all areas in the specified address range will be
deleted (unless an area is covered only partially).
* Introduced B_SHARED_AREA flag, which is set on areas that have been
created by {vm,_user}_map_file() with REGION_NO_PRIVATE_MAP. When
fork()ing those areas won't be copied CoW, but rather be cloned. This
is needed for mmap() MAP_SHARED.
* {vm,_user}_map_file() also accept an FD argument < 0, in which case an
anonymous area is created.
* Implemented mmap() and munmap(). Currently there's the restriction
that we can't partially unmap areas. Otherwise the functions should be
rather compliant. We also support the non-POSIX extension
MAP_ANONYMOUS.
