Windows' timer resolution is limited to 15ms accuracy. This was breaking dynamic intensity since it tries to measure below this.
Since we are repeatedly sampling similar timeframes, we can average the gpu_us result over 5 different values to get very fine precision.

Bugfix: Use a mutex to control non-curses output
Without this, there is no guarantee writes won't overlap (and it happens quite a bit on Windows with the bitforce driver)

Use a pthread conditional that is broadcast whenever work restarts are required. Create a generic wait function waiting a specified time on that conditional that returns if the condition is met or a specified time passed to it has elapsed. Use this to do smarter polling in bitforce to abort work, queue more work, and check for results to minimise time spent working needlessly.
