Review request for Asterisk Developers.


Changes
-------

for real this time.


Summary
-------

1) Fix a sip_pvt reference leak.  If the scheduler callback returned 0, it did not release the reference to the associated sip_pvt.
    
2) Add locking in the scheduler callback.  This code runs from the scheduler, which is executed in the SIP monitor thread.  A channel thread will be working with the sip_pvt at the same time.  Use sip_pvt_lock_full to ensure that the ast_channel/sip_pvt locking order is honored.


This addresses bug ASTERISK-18979.
