* mISDN >= 1.2 provides a dsp pipeline for i.e. echo cancellation modules, make chan_misdn use it.

* add a check for linux/mISDNdsp.h to configure.ac and update the autogenerated files: 'configure', 'autoconfig.h.in'
  (the 'configure' script was not in sync with the latest configure.ac, so the diff is a bit bigger than expected).
