16a93128f8 Fix harmless compiler warnings.

f5ddb9c214 Take out the goofy '$$' path syntax. Instead, use subtypes to communicate when 
a string is JSON.  Add the json() function that validates and minifies the
JSON and sets the appropriate subtype.

383de6918c Create separate "path" and "root" columns in the json_each() and json_tree() 
virtual tables.  "Root" is the 2nd parameter and is fixed.  
"Path" varies as json_tree() walks the hierarchy.

3ad93bba84 Enhance the json_extract() function so that if given multiple PATH arguments 
it will return a JSON array with all of the answers.  Also update comments
within the json1 extension to reflect stricter interpretation of JSON and PATH
arguments.

a json function (other than json_valid()) is not valid JSON.
