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.

avformat/movenc: Fix segfault when remuxing rtp hint stream
...
When remuxing an rtp hint stream (or any stream with the tag "rtp "),
the mov muxer treats this as one of the rtp hint tracks it creates
internally when ordered to do so; yet this track lacks the
AVFormatContext for the hinting rtp muxer, leading to segfaults in
mov_write_udta_sdp() if a "trak" atom is written for this stream; if not,
the stream's codecpar is freed by mov_free() as if the mov muxer owned
it (it does for the internally created "rtp " tracks), but without
resetting st->codecpar, leading to double-frees lateron. This commit
therefore ignores said tag which makes rtp hint streams unremuxable.
This fixes tickets #8181 and #8186 .

avformat/adtsenc: return value check for init_get_bits in adts_decode_extradata

'buf' is part of 'AVPacket pkt'.
replace init_get_bits with init_get_bits8.
