Add runtime version checking functions

Browse Source 
This patch adds two new exported functions:

* `jansson_version_str` - Returns a human-readable version number
* `jansson_version_cmp` - Returns an integer less than, equal to, or greater
  than zero if the runtime version of Jansson is found, respectively, to be
  less than, to match, or be greater than the provided major, minor, and micro.
