Message:

More ticket #982 (MWI): support for Asterisk unsolicited MWI requests:

• undo r3019 which put unsolicited MWI support in pjsua app only
• put the unsolicited MWI support in PJSUA-LIB instead
• unsolicited MWI is by default enabled
• on_mwi_info() callback will be called just as the solicited MWI version
