FS-9307: [mod_conference] don't close files until after video threads are done to avoid race condition trying to use closed file handle when playing a video file

FS-9305: [mod_conference] return the logo image path from video-logo-img api and handle passing no image path

FS-9303 these checks are no longer needed as the video flag is not sent to file open unless we are in transcode mode, you can record mp4 but it will only contain the audio if in passthru mode.

This reverts commit 7150cede.

FS-9287 Add channel variable to make spandsp_start_tone_detect easier to use from dialplan / embedded scripts.
The following variables are added:

execute_on_spandsp_tone_detect_<TONE NAME> : executes APP when tone is detected.  For example, if you have a tone
    named "SIT" defined in spandsp.conf.xml, the variable would be "execute_on_spandsp_tone_detect_SIT"

api_on_spandsp_tone_detect_<TONE NAME> : similar to execute_on except that it executes an API.

spandsp_tone_detect_stop_on_tone : default is false.  If true, detector will stop once the first matching tone is detected.

FS-9260: fix make detection to not fail on openbsed, and fix libtoolize detection to attempt to find libtoolize the same version as specified libtool
