d4b7b3c03e lavc/pthread_frame: avoid leaving stale hwaccel state in worker threads 
This state is not refcounted, so make sure it always has a well-defined
owner.

Remove the block added in 091341f2ab, as
this commit also solves that issue in a more general way.

8e98dfc57f lavf/tls_mbedtls: add support for mbedtls version 3 
- certs.h is gone. Only contains test data, and was not used at all.
- config.h is renamed. Was seemingly not used, so can be removed.
- MBEDTLS_ERR_SSL_NO_USABLE_CIPHERSUITE is gone, instead
  MBEDTLS_ERR_SSL_HANDSHAKE_FAILURE will be thrown.
- mbedtls_pk_parse_keyfile now needs to be passed a properly seeded
  RNG. Hence, move the call to after RNG seeding.
