Clean up some memory leaks

Browse Source 
Move the  FFTW3 cleanup  into the  main routine as  it should  only be
called  once rather  than  every time  the  settings configuration  is
changed or reset (MultiSettings).

Call the new fini_ldpc_ routine before  exiting in the main routine to
free the LDPC resources.
