  Log Message:
  -----------
  dialog: Add quotation mark escaping in get_dialogs_by_val()

In case a dialog value contained the '"' character (ASCII 34), such as
values stored by pua_dialoginfo, the resulting JSON would be invalid.

Also optimize the function code a bit, by merging lots of
DEC_AND_CHECK_LEN() calls together wherever possible.
