56cc024220 avformat/mpc8: fix hang with fuzzed file 
This can lead to an endless loop by seeking back a few bytes after each
attempted chunk read. Assuming negative sizes are always invalid, this
is easy to fix. Other code in this demuxer treats negative sizes as
invalid as well.

Fixes ticket #4262.

e3528d2a7b mov: Implement parsing of the "HandlerName" from the MP4 HDLR atom 
This atom typically is used for a track title. The handler name is stored
as a Pascal string in the QT specs (first byte is the length of the string),
so do not export it.

A second length check based on the first character is added to avoid
overwriting an already specified handler_name (it happens with YouTube
videos for instance, the handler_name get masked), or specifying an
empty string metadata.

The Pascal string fix and the second length check are written
by Clément Bœsch <clement.boesch@smartjog.com>.

6a0cd529a3 avformat/tta: fix crash with corrupted files 
av_add_index_entry() can fail, for example because the parameters are
invalid, or because memory allocation fails. Check this; it can actually
happen with corrupted files.

The second hunk is just for robustness. Just in case functions like
ff_reduce_index() remove entries. (Not sure if this can actually
happen.)

Fixes ticket #4294.

48e36f8a12 libavformat/mpegtsenc: allow to set service_type in sdt 
This adds an option to set the service type in mpegts as defined in ETSI 300 468.

I added what I believe are the most useful service types as pre defined values,
the others can be sent by using their hexdecimal form directly (e.g. -mpegts_service_type digital_radio, -mpegts_service_type 0x07).

I've been using this patch in order to pipe internet radio stream (originally as HLS/m3u8) from ffmpeg to tvheadend,
when the service type set right tvheadend recognize the mpegts stream as a radio channel.

The patch in its original form was written by linuxstb from freenode's hts channel which allowed me pushing it upstream.

This close issue 4118.

3c18a7b188 avio: Do not consider the end-of-buffer position valid 
Trigger a refill if the seek action moves the pointer
at the end of the buffer.

Before this patch the read action following the seek would trigger
the refill, while write action would write outside the buffer.

In the Libav codebase few muxers seek forward outside of what
already has been written so it is quite unlikely to experience
the problem with the default buffer size.
