Subject: [PATCH] Added options to DTSC pull for controlling the buffer config.
 Made 8X target duration the default buffer size. Inputs now wait for
 INPUT_TIMEOUT *and* two biggestFragment durations, added a few helper
 functions to DTSC::Meta. Buffer now automatically sets segment size to
 min(configed_size, biggest_fragment/2) to prevent sudden reductions of
 fragment sizes by more than 50%
