[pgpool-committers: 10420] pgpool: Fix json_writer did not properly encode special characters.

[Bo Peng]

Fix json_writer did not properly encode special characters.

Pgpool would crash when the watchdog was enabled if wd_authkey contained special characters (e.g., a backslash).

The patch was originally created by Martijn van Duren and revised by Bo Peng.
