- Factorize Mifare*Tag as MifareTag;
- Factorize mifare_*_get_tags() / mifare_*_free_tags() as freefare_get_tags() and freefare_free_tags();
- Add a new freefare_get_tag_type() function to get a tag type;
- Update regression test suite;
- Update example.
While this is a major change that basically change all the API, programs using libfreefare should be easily modified by replacing any Mifare*Tag variable by a generic MifareTag one, adding a few lines of code to check the target's type using freefare_get_tag_type(), and changing any call to mifare_*_get_tags() / mifare_*_free_tags() by the generic freefare_get_tags() and freefare_free_tags() functions.
