FS-7300 [mod_rayo] set iq type to error when prompt component forwards input/output error back to rayo client.

FS-7378 #resolve #comment play_and_detect_speech can now detect DTMF if you set the playback_terminators channel variable to any or specific DTMF.  The result will be stored in speech_detect_result and in playback_terminator_used.  Also added channel variable play_and_detect_speech_close_asr which will release the speech recognition port when the detection is completed.  This will prevent speech licenses from being held the entire call.

* commit '7a6303d6':
  Add minimal configuration for configuring FreeSWITCH from scratch

The default "vanilla" configuration that comes with FreeSWITCH has
been designed as a showcase of the configurability of the myriad of
features that FreeSWITCH comes with out of the box. While it is very
helpful in tinkering with FreeSWITCH, it has a lot of extraneous stuff
enabled/configured for use in a production system. This configuration
aims to take the reverse stance -- it attempts to be a starting point
for configuring a new system by "adding" required features (instead of
removing them as one would do if one starts with the default
configuration).

  FS-7352: Document how to use switch_core_set_variable to delete variables

I had to scan through the source of the function to verify that this
is the indeed the actual behaviour, and that NULL is a valid
argument. By mentioning this in the header, we save posterity that
effort.
