The chan_dahdi faxdetect option only works for the first FAX call.

The chan_dahdi faxdetect option only works for the first call.  After that
the option no longer works.  The struct dahdi_pvt.callprogress member is
the encoded user config setting for the callprogress and faxdetect config
options.  Changing this value alters the configuration for all following
calls until the chan_dahdi.conf file is reloaded.

* Fixed the chan_dahdi ast_channel_setoption callback to not change the
users faxdetect config setting except for the current call.

* Fixed the chan_dahdi ast_channel_queryoption callback to read the active
DSP setting of the faxdetect option.

* Made actually disable the active faxdetect DSP setting for the current
call on the analog port.  my_handle_dtmfup() is used for normal analog
ports.  dahdi_handle_dtmfup() is the legacy code and is no longer used
unless in a radio mode.
