&nbsp;&nbsp;Fix channel redirect out of MeetMe() and other issues with channel softhangup.<br/>
&nbsp;&nbsp;<br/>
&nbsp;&nbsp;Mantis issue #18585 reports that a channel redirect out of MeetMe() stopped<br/>
&nbsp;&nbsp;working properly.&nbsp; This issue includes a patch that resolves the issue by<br/>
&nbsp;&nbsp;removing a call to ast_check_hangup() from app_meetme.c.&nbsp; I left that in my<br/>
&nbsp;&nbsp;patch, as it doesn't need to be there.&nbsp; However, the rest of the patch fixes<br/>
&nbsp;&nbsp;this problem with or without the change to app_meetme.<br/>
&nbsp;&nbsp;<br/>
&nbsp;&nbsp;The key difference between what happens before and after this patch is the<br/>
&nbsp;&nbsp;effect of the END_OF_Q control frame.&nbsp; After END_OF_Q is hit in ast_read(),<br/>
&nbsp;&nbsp;ast_read() will return NULL.&nbsp; With the ast_check_hangup() removed, app_meetme<br/>
&nbsp;&nbsp;sees this which causes it to exit as intended.&nbsp; Checking ast_check_hangup()<br/>
&nbsp;&nbsp;caused app_meetme to exit earlier in the process, and the target of the<br/>
&nbsp;&nbsp;redirect saw the condition where ast_read() returned NULL.<br/>
&nbsp;&nbsp;<br/>
&nbsp;&nbsp;Removing ast_check_hangup() works around the issue in app_meetme, but doesn't<br/>
&nbsp;&nbsp;solve the issue if another application did the same thing.&nbsp; There are also<br/>
&nbsp;&nbsp;other edge cases where if an application finishes at the same time that a<br/>
&nbsp;&nbsp;redirect happens, the target of the redirect will think that the channel hung<br/>
&nbsp;&nbsp;up.&nbsp; So, I made some changes in pbx.c to resolve it at a deeper level.&nbsp; There<br/>
&nbsp;&nbsp;are already places that unset the SOFTHANGUP_ASYNCGOTO flag in an attempt to<br/>
&nbsp;&nbsp;abort the hangup process.&nbsp; My patch extends this to remove the END_OF_Q frame<br/>
&nbsp;&nbsp;from the channel's read queue, making the &quot;abort hangup&quot; more complete.&nbsp; This<br/>
&nbsp;&nbsp;same technique was used in every place where a softhangup flag was cleared.<br/>
&nbsp;&nbsp;<br/>
&nbsp;&nbsp;(closes issue #18585)<br/>
