Ensure chan->fdno always gets reset to -1 after handling a channel fd event.

Since setting fdno to -1 had to be moved, a couple of other code paths that
do process an fd event return early and do not pass through the code path
where it was moved to.  So, set it to -1 in a few other places, too.

Make it easier to detect an improper call to ast_read().

When you call ast_waitfor() on a channel, the index into the channel fds array
that holds the file descriptor that poll() determines has input available is
stored in fdno.  This patch clears out this value after a call to ast_read()
and also reports errors if ast_read() is called without an fdno set.

From a discussion on the asterisk-dev list.

Move ast_waitfor() down to avoid the results of the API call becoming stale.

This call to ast_waitfor() was being done way too soon in this section of code.
Specifically, there was code in between the call to waitfor and the code that
uses the result that puts the channel in autoservice.  By putting the channel
in autoservice, the previous results of ast_waitfor() become meaningless,
as the autoservice thread will do it's own ast_waitfor() and ast_read()
on the channel.

So, when we came back out of autoservice and eventually hit the block of code
that calls ast_read() on the channel, there may not actually be any input on
the channel available.  Even though the previous call to ast_waitfor() in
app_meetme said there was input, the autoservice thread has since serviced
the channel for some period of time.

This bug manifested itself while dvossel was doing some testing of MeetMe in
Asterisk trunk.  He was using the timerfd timing module.  When the code hit
ast_read() erroneously, it determined that it must have been called because of
input on the timer fd, as chan->fdno was set to AST_TIMING_FD, since that was 
the cause of the last legitimate call to ast_read() done by autoservice.  

In this test, an IAX2 channel was calling into the MeetMe conference.  It was
_much_ more likely to be seen with an IAX2 channel because of the way audio
is handled.  Every audio frame that comes in results in a call to
ast_queue_frame(), which then uses ast_timer_enable_continuous() to notify
the channel thread that a frame is waiting to be handled.  So, the chances
of ast_waitfor() indicating that a channel needs servicing due to a timer
event on an IAX2 event is very high.

Finally, it is interesting to note that if a different timing interface was
being used, this bug would probably not be noticed.  When ast_read() is called
and erroneously thinks that there is a timer event to handle, it calls the
ast_timer_ack() function.  The pthread and dahdi timing modules handle the
ack() function being called when there is no event by simply ignoring it.
In the case of the timerfd module, it results in a read() on the timer fd
that will block forever, as there is no data to read.  This caused Asterisk
to lock up very quickly.

Thanks to dvossel and mmichelson for the fun debugging session.  :-)

Ensure that only one thread is calling ast_settimeout() on a channel at a time.

For example, with an IAX2 channel, you can have both the channel thread and the
chan_iax2 processing threads calling this function, and doing so twice at the
same time is a bad thing.

Previously, only the "data" field of the sip_pkt created during __sip_reliable_xmit 
was freed when XMIT_ERROR was returned by __sip_xmit. When retrans_pkt was called,
this inevitably resulted in the reading and writing of freed memory.

XMIT_ERROR is a condition meaning that we don't want to attempt resending the packet
at all. The proper action to take is to remove the scheduler entry we just created,
free the packet's data as well as the packet itself, and unlink it from the list of
packets on the sip_pvt structure.

  This change moves the default feature digit timeout to 1000 ms from the previous default of 500.
  
  As per bug 14515, a dev discussion arrived at a "mediated concensus" 
  of a default feature digit timeout of 1.0 sec. Some voted for 1300;
  ctooley thought 1500 for distracted phone users in phone booths; 
  kpfleming put his foot down at 1.0 sec. 
  
  Users who found the previous default max delay of 250 msec perfect,
  are welcome to override the new default. Notice that I said that
  250 msec was the default; wait a minute, you might say, the config
  file said it was 500 msec!; well, because of the bug fix for 14515,
  we found that 500 msec was actually enforcing a max of 250. The bug
  fix would restore 500 msec, but we felt even that was a bit tight
  for most users... 2000 msec was pushed earlier by mmichelson, so
  that reduces to 1000 msec after the bug fix. Enjoy!

  IAX2 prune realtime fix
  
  Now prune_users() and prune_peers() are called instead of reload_config() to prune all users/peers that are realtime.  These functions remove all users/peers with the rtfriend and delme flags set. iax2_prune_realtime() also lacked the code to properly delete a single friend.  For example. if iax2 prune realtime <friend> was called, only the peer instance would be removed. The user would still remain.

  This patch prevents the feature detection timeout from being cut in half.
  
  Because the ast_channel_bridge() call will return 0 and pass
  a frame pointer for both DTMF_BEGIN and DTMF_END, the feature_timer
  field in hte config struct is getting decremented twice, which 
  effectively cuts the digittimeout in half. I added conditions
  to the if statement to only let DTMF_END frames to flow thru,
  which solved the problem. Also, when the frame pointer is null,
  let control flow thru-- this usually happens on timeouts. I added
  a comment to the code to explain what's going on and why.
  
  Many thanks to sodom for reporting this problem. Personnally, it always seemed
  like something was wrong with the featuredigittimeout, but I never
  could quite decide what... and was too busy to investigate.
  This bug forced the issue, and now we know.
  
  Sodom had other issues in 14515, but I couldn't reproduce them. If
  he still has problems, and wants to get them solved, he is welcome
  to reopen 14515.

Iax2 prune realtime had issues.  If "iax2 prune realtime all" was called, it would appear like the command was successful, but in reality nothing happened.  This is because the reload that was supposed to take place checks the config files, sees no changes, and does nothing.  If there had been a change in the the config file, the realtime users would have been marked for deletion and everything would have been fine.  Now prune_users() and prune_peers() are called instead of reload_config() to prune all users/peers that are realtime.  These functions remove all users/peers with the rtfriend and delme flags set. iax2_prune_realtime() also lacked the code to properly delete a single friend.
