Leonardo Francisco 52f0d540dd validity: Iteration 6 — Enrollment, Verification, and DB Management 
Add core fingerprint operations: enrollment, verification, identification,
print listing, print deletion, and storage clearing.

New files:
- validity_db.h/c: On-chip template database operations — command builders
  for all DB commands (0x45-0x4B, 0x47-0x48, 0x51, 0x5E, 0x60, 0x62, 0x63,
  0x64, 0x68, 0x69, 0x6B), response parsers for DB info/user storage/user/
  record value/record children/new record ID, identity builder (UUID→VCSFW
  binary), finger data builder, and db_write_enable blob accessor.
- validity_enroll.c: 31-state enrollment SSM with interrupt-driven finger
  detection (EP 0x83), capture command orchestration via build_cmd_02(),
  enrollment session management (create/update/commit), DB record creation
  (user + finger), and LED glow feedback.
- validity_verify.c: 17-state verify/identify SSM with match command
  dispatching (cmd 0x5E for verify, cmd 0x60 for identify), 6-state list
  SSM for enumerating enrolled prints via GPtrArray, 8-state delete SSM,
  and clear_storage stub.

Modified files:
- validity.h: Added DB header include, 5 new state enums (CalibState,
  EnrollState, VerifyState, ListState, DeleteState), new struct fields
  for enrollment/verification/list/delete state, function declarations.
- validity.c: Replaced all operation stubs with real implementations,
  added cleanup for new fields in dev_close, wired all FpDevice methods.
- meson.build: Added 3 new source files to driver.
- tests/meson.build: Added test-validity-db executable.
- tests/validity/custom.py: Updated feature assertions (STORAGE,
  STORAGE_LIST, STORAGE_CLEAR now enabled).

Tests: 29 new unit tests in test-validity-db.c covering all command
builders, response parsers, identity/finger data builders, and blob
accessor. All 37 tests pass (0 fail, 2 skip).

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.
