[asterisk-dev] Avoid audio loss in ChanSpy (ref: ASTERISK-25866)

As described in the issue ASTERISK-25866
<https://issues.asterisk.org/jira/browse/ASTERISK-25866>, it appears
that ChanSpy is randomly loosing audio frames, because it sets the flags
AST_AUDIOHOOK_TRIGGER_SYNC and AST_AUDIOHOOK_SMALL_QUEUE when creating
the audiohook: these option cause the audiohook's queue to be flushed of
"old" frames at very short intervals.
I have submitted a patch on gerrit which does two things :
1- do not set the flag AST_AUDIOHOOK_TRIGGER_SYNC if ChanSpy has been
called with the option "o": in this case we only listen to the audio
coming from this channel so this flag is useless
2- create a new option "l" which prevents the flag
AST_AUDIOHOOK_SMALL_QUEUE from being set. I find it better than just
removing the flag in all cases, because this may introduce some delay in
the audio, which may not be acceptable for many ChanSpy users.
What do you think of the idea ?
