Leonardo Francisco ae3f3a2479 validity: add 16 regression tests for Iter6 audit fixes 
Adds test-validity-verify.c with 16 unit tests that prevent regression
of all 8 issues found during the Iteration 6 code audit (b05657f):

  R1: parse_match_result TLV parsing (5 tests)
    - valid payload with all fields extracted correctly
    - multi-tag iteration (tag ordering independence)
    - empty dict returns no-match
    - truncated/malformed data handled gracefully
    - unknown tags skipped without error

  R1f: match_result_clear frees hash and zeros struct

  R2: identity builder NULL rejection (2 tests)
    - NULL uuid returns NULL (prevented g_variant_new_string crash)
    - valid UUID produces correct identity bytes

  R3: gallery matching by subtype (3 tests)
    - matches correct print by finger subtype
    - falls back to first entry when subtype not found
    - returns NULL for empty/NULL gallery

  R4: struct field separation — enroll_user_dbid != delete_storage_dbid

  R5: del_record command format — cmd 0x48 with dbid(2LE)

  R6: match_finger single allocation — exactly 13 bytes

  R7: SSM state enums exist (2 tests)
    - CLEAR_* states 0-5
    - DELETE_* states 0-7

To make the tests possible, extracted previously-static functions:
  - parse_match_result → validity_parse_match_result (public)
  - ValidityMatchResult struct moved to validity_db.h
  - validity_match_result_clear added to validity_db.c
  - validity_find_gallery_match helper extracted from verify SSM

History

LibFPrint was originally developed as part of an academic project at the University Of Manchester.

It aimed to hide the differences between consumer fingerprint scanners and provide a single uniform API to application developers.

Goal

The ultimate goal of the FPrint project is to make fingerprint scanners widely and easily usable under common Linux environments.

License

Section 6 of the license states that for compiled works that use this library, such works must include LibFPrint copyright notices alongside the copyright notices for the other parts of the work.

LibFPrint includes code from NIST's NBIS software distribution.

We include Bozorth3 from the US Export Controlled distribution, which we have determined to be fine being shipped in an open source project.
