/**
 * Avoid periods to overlap.
 *
 * According to DASH guidelines, if a period has media duration longer than
 * the distance between the start of this period and the start of the next period,
 * use of start times implies that the client will start the playout of the next
 * period at the time stated, rather than finishing the playout of the last period.
 *
 * Even if that case if defined when period last(s) segment(s) is/are a bit longer,
 * it can be meaningful when two periods are overlapping. We will always shorten
 * the first period, and even erase it if its duration is equal to zero.
 *
 * Example (Periods are numbered under their manifest order) :
 *
 * [ Period 1 ][ Period 2 ]       ------>  [ Period 1 ][ Period 3 ]
 *             [ Period 3 ]
 *
 * [ Period 1 ][ Period 2 ]       ------>  [ Period 1 ][  2  ][ Period 3 ]
 *                  [ Period 3 ]
 *
 * [ Period 1 ][ Period 2 ]       ------>  [  1  ][      Period 3     ]
 *        [      Period 3     ]
 *
 * @param {Array.<Object>} parsedPeriods
 * @return {Array.<Object>}
