528a6f8a23 Refactor filter in LinkDB

  * Smallhash regex has been rewritten.
  * Unit tests update

68bc21353a Session ID: extend the regex to match possible hash representations
Improves #306
Relates to #335 & #336
Duplicated by #339

Issues:
 - PHP regenerates the session ID if it is not compliant
 - the regex checking the session ID does not cover all cases
   - different algorithms: md5, sha1, sha256, etc.
   - bit representations: 4, 5, 6

Fix:
 - `index.php`:
   - remove `uniqid()` usage
   - call `session_regenerate_id()` if an invalid cookie is detected
 - regex: support all possible characters - '[a-zA-Z,-]{2,128}'
 - tests: add coverage for all algorithms & bit representations
