and thread spinlock was reverse in Wait() and Notify(). The thread lock
is now the outer lock -- this way it is still possible to call Notify()
with the thread lock being held.

Condition variables would never be interrupted.
* ConditionVariableEntry::Add() did not correctly insert the entry into
the per-thread list of entries (the next link of the previous entry
was not adjusted), which could leave the entry unnotified when the
previous entry was notified, thus leaving it in the respective
condition variable's list after the end of its life time. This should
fix a crashing bug I rarely encountered.
* Added debug checks in the PrivateConditionVariableEntry
constructor/destructor that should have helped me to find
forementioned bug hours earlier, had I been bright enough to realize
that I didn't include <debug.h> and those KDEBUG guarded checks were
never executed. :-/

removed from the variable, which could lead to crashes under certain
cicrumstances.

exists and thread was notified), B_ENTRY_NOT_FOUND (condition variable
not found or Unpublish()ed while waiting), or B_INTERRUPTED
(interrupted by a signal).

* Removed left-over commented C implementation.
* It is now possible for a thread to wait for more than one condition
variable at a time.
* Made waiting for condition variables optionally interruptable.
* Renamed Notify() method to NotifyAll() and added a NotifyOne(), so
that it is now possible to wake up only one of the waiting threads.
Pretty much untested at the moment.
