Don't send a semicolon over the wire in sip notify messages.
Caused by fix for issue 9938.

I basically took the code that existed before 9938 was fixed, and
 copied it into a new function - ast_unescape_semicolon

There should be very few places this will be needed (pbx_config
 does NOT need this (see issue 9938 for details))

Issue 10430, patch by me, with help/ideas from murf (thanks murf).
