Change subject: Audit ast_json_pack() calls for needed UTF-8 checks.
......................................................................
Audit ast_json_pack() calls for needed UTF-8 checks.
Added needed UTF-8 checks before constructing json objects in various
files for strings obtained outside the system. In this case string values
from a channel driver's peer and not from the user setting channel
variables.
* aoc.c: Fixed type mismatch in s_to_json() for time and granularity json
object construction.
