5abdda214d avcodec/utils: implement avcodec_alloc_frame() through av_alloc_frame()
This ensures that theres just one AVFrame allocation function and libs dont
produce multiple AVFrame variants after a minor lib update

5fe415f0f4 UDP: join multicast group on the interface specified with &localaddr=
When joining multicast groups, ffmpeg was using INADDR_ANY as interface address
which leads to enabling the multicast group on the interface with "default gateway".
Often multicast traffic is received over dedicated interface, which scenario ffmpeg was
unable to handle. With this patch, ffmpeg will enable multicast group to the interfaces
configured with address specified in &localaddr= parameter of udp:// URL. To avoid
loacal_addr resolve at udp_close(...) the UDPContext structure was extended with
struct sockaddr_storage local_addr_storage member, which is populated in udp_open(..)
and passed to udp_join_multicast_group()  and udp_leave_multicast_group().

ec464c9683 avcodec/utils: av_register_codec & hwaccel() that work in O(1) time
Its possible to implement this with a few lines less code but it then
would flip the order of the list and require registration of external
codecs to be done first, also it could break user applications due to
this. Thus to maintain ABI this slighty more complex solution is
used.

mplayer is one.
Theres no hurry in removing the code, it can as well be removed once
no projects use it anymore

6eda91ad54 mpegts: stop analyzing when pmt for all programs have been found
This disables NOHEADER after finding PMT for all programs to
avoid find_stream_info always exhausting probe size for mpegts.

This is very important for live streams since read speed
will be limited. rtsp, udp and any protocol streaming a live
mpegts will have dramatically faster startup time.

Note, lack of codec parameters for streams can still cause
the full probe size to be exhausted.
