058f3dbb27 The json_valid() function only returns true for pure JSON. JSON5 (or 
at least that subset of JSON5 that has been so far implemented) is accepted
by all routines, but json_valid() still returns false for JSON5 inputs.
The new json_valid5(X) routine returns true or false if X is or is not valid
JSON5.  All of this is experimental and subject to change.
