Byte string printing

Browse Source 
Added functions:
- cJSON_PrintWithLengthGet and cJSON_PrintUnformattedWithLengthGet to be
  able to get a length of a printed buffer and to not rely on it being
  null terminated
- cJSON_CreateByteString to create a string of a certain length (without
  relying on it being null terminated)
- cJSON_AddByteStringToObject to add a string of a certain length to an
  object (without relying on it being null terminated)
