[MPlayer-dev-eng] Make -nortc the default?

[Uoti Urpala]

Does anyone have a reason why rtc timing should still be used by
default?

Reasons not to use it:
- Most desktop Linux boxes have HZ 1000 or at least 250 nowadays. HZ
  1000 gives accuracy comparable to RTC using normal sleep, and 250 is
  probably still high enough. Thus rtc doesn't give any benefit in most
  cases.
- rtc wakes up the process 1024 times a second while sleeping, wasting
  CPU that could be used for other processes
- rtc requires the user to set special permissions for /dev/rtc/, and if
  that hasn't been done it shows error messages telling the user to
  modify system startup scripts.
