Fix hstore_to_json_loose's detection of valid JSON number values.
We expose a function IsValidJsonNumber that internally calls the lexer
for json numbers. That allows us to use the same test everywhere,
instead of inventing a broken test for hstore conversions. The new
function is also used in datum_to_json, replacing the code that is now
moved to the new function.
Backpatch to 9.3 where hstore_to_json_loose was introduced.
