7a2280fe65 Multiple optimizations that try to preserve or infer the zero-terminated 
property of TEXT values.  Avoid unnecessary copying of text values destined
to become function parameters.  All changes help improve performance of
doing UPDATEs on large JSON values that are indexed multiple ways.

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.
