Fixed few bugs that seem to have been introduced by new dialog 
locking algorithm:
- Fixed crash in PJSUA-API when initiating client subscription
- Fixed another crash in PJSUA-API when hanging-up call

Also fixed SDP negotiator:
- add a=inactive when rejecting media line 

Also increase maximum log size from 1500 to 2000 since some
SIP packet is quite large. A little bit of Warning: 
** THIS MAY AFFECT APPLICATION'S STACK USAGE **
