util: debugstacktrace, flush before and after writing...

util: debugstacktrace, flush before and after writing Close another stream (default stdout, which often is buffered) before writing to the primary stream (default stderr, which often is unbuffered). The primary stream is also flushed after writing (in case it is buffered). This fixes non-deterministic output order, especially on windows.
