- demux: fix nasty bug where setting multiple filters resulted in ts
  packet duplication

- frontend: merge frontend improvements from 2.4 DVB tree:

  - schedule_timeout(1) in dvb_frontend.c after setting frontend and
    before waking up frontend thread

  - do FE_RESET in each iteration of frontend thread if !FE_HAS_LOCK

  - use aquire_signal flag to call FE_RESET only after tuning until
    FE_HAS_LOCK has been signalled, and not when FE_HAS_LOCK drops out for
    short periods of time later

- follow frontend changes in ves1x93 driver
