Improve error reporting in jsonpath 

This commit contains multiple improvements to error reporting in jsonpath
including but not limited to getting rid of following things:

 * definition of error messages in macros,
 * errdetail() when valueable information could fit to errmsg(),
 * word "singleton" which is not properly explained anywhere,
 * line breaks in error messages.
