8f907b25ba Relicense project under the GNU Affero General Public License v3 (AGPLv3) 
and add the Enterprise / Commercial licensing option.

Main changes:
- Replace GPLv3 headers with AGPLv3 headers in source files.
- Update LICENSE file to the full AGPLv3 text.
- Add ENTERPRISE.md describing the dual-licensing model:
  * Community Edition: AGPLv3 (strong copyleft, including network use).
  * Enterprise / Commercial Edition: proprietary license for production /
    multi-user / OEM use without the obligation to disclose derivative code.
- Update README with a new "License and Commercial Use" section pointing to
  ENTERPRISE.md and clarifying how companies can obtain a commercial license.

Why this change:
- AGPLv3 ensures that modified versions offered as a service or deployed
  in production environments must provide corresponding source code.
- The Enterprise / Commercial edition provides organizations with an
  alternative proprietary license that allows internal, large-scale, or OEM
  use (bulk provisioning, policy enforcement, inventory / revocation,
  custom attestation, signed builds) without AGPL disclosure obligations.

This commit formally marks the first release that is dual-licensed:
AGPLv3 for the Community Edition and a proprietary commercial license
for Enterprise customers.

fa6292118d Major refactor of USB CCID and USB HID interfaces. All interfaces are rewritten. 
With this new scheme we ensure that:
- memcpy's are reduced.
- no race conditions are performed.
- critical areas are protected.
- callbacks are executed immediately.
- write's are executed after the positive report is received.
- no usb middle interface anymore.
- CCID and HID are totally independent.

11447371fe Rewritten continuous flow for HID. 
HID uses complete_cb to send the next packet and not the value returned by tud_write. Therefore, no other writes can happen in between of a writing packet if fails.

This ensures a proper interface multiplexing and continuous flow.

Also, the read pointer is used to multiplex usb packets.
