Add tests and descriptions for the functions in json_util.c

Also refactor json_object_from_file to use json_object_from_fd
internally.

Signed-off-by: Michael Heimpold <mhei@heimpold.de>

Eliminate all uses of bits.h within the json-c code.

filename should be passed as const char* to functions
json_object_to_file and json_object_to_file

There are now three options: JSON_C_TO_STRING_SPACED, JSON_C_TO_STRING_PLAIN and JSON_C_TO_STRING_PRETTY.
This also add a json_object_to_file_ext() that takes the same flags.
Existing output of json_object_to_json_string() is unchanged, and uses JSON_C_TO_STRING_SPACED.
Thanks fo Grant Edwards for the initial patches.
