Message:

Ticket #933: Incoming OPTIONS may trigger assertion if it arrives when PJSUA-LIB is being shutdown (thanks Johan Lantz for the report)

• destroy the media subsystem after busy_sleep(1000) in the shutdown sequence
• also handle the case when OPTIONS arrives just when PJSUA-LIB is being initialized and media transport is not ready (in this case just reply OPTIONS without message body)
