Make QWindowsPipeWriter thread-free.
Re-work QWindowsPipeWriter to not use a thread anymore but the
WriteFileEx API, similar to QWindowsPipeReader. This saves us a lot of
thread synchronization code and enables us to directly write data
without yet another buffering layer.
Also, this fixes the dreaded deadlocks in the QWindowsPipeWriter
destructor that could occur when the reading end was closed before
the write was finished.
