5736ba5ac3 Update json_each() and json_tree() so that they work with JSONB inputs.

ee50aad865 The u.zJContent field of JsonNode for a string or label should NOT include 
the quotation mark delimiters.  Ever.  This is an inefficiency that really
ought to be fixed on trunk, but that can wait until this branch lands.

a7ec1f9a1b Fix a bug in json_array_length() introduced in version 3.43.0 by 
check-in [df099ad713011b67].  If the JSON input comes from json_remove(),
the removed array entries are still counted as part of the array length.

91c0092917 Up until version 3.42.0, there was a bug in json_valid() such that it would 
return False (0) for a NULL input.  That bug is fixed in 3.42.0.  This
check-in adds a compile-time option -DSQLITE_LEGACY_JSON_VALID that restores
the old buggy behavior for applications that depend on it.
