  Remove ability to control T.38 FAX error correction from udptl.conf.
  
  chan_sip has had the ability to control T.38 FAX error correction mode on a per-peer
  (or global) basis for a couple of releases now, which is where it should have been
  all along. This patch removes the ability to configure it in udptl.conf, but issues
  a warning if the user tries to do, telling them to look at sip.conf.sample for how
  to configure it now. For any SIP peers that are T.38 enabled in sip.conf, there is
  already a default for FEC error correction even if the user does not specify any mode,
  so this change will not turn off error correction by default, it will have the same
  default value that has been in the udptl.conf sample file.
