Use the first 64 bits of the SHA1 of the content as file UID
instead of a random number if the bitexact flag is set.

Fixes #1697.

There can be only one track reference. The multiple tref handling is
handled at a different level.

This was broken in 0d96ec19eb under the
assumption that there is only one tref leaf atom.

Fixes Ticket #2081.

Limelight is a not too uncommon CDN. The authentication scheme is
pretty similar to the adobe authentication, but is even closer to
normal http digest authentication (but not close enough to warrant
sharing code) than the adobe version.

This is mostly used to authenticate the client when publishing.
Tested with wowza and akamai.

Some but not all servers support resending a new connect invoke
within the same connection, so always reconnect for sending a new
connection attempt. This matches what other applications do as well.

The authentication scheme is structurally pretty similar to http
digest authentication, but uses base64 instead of hex strings.

Current MicroDVD AVPackets contain timing information and trailing line
breaks. The data is now only composed of the markup data. Doing this
consistently between text subtitles decoders allows to use different
codec for various formats. For instance, MicroDVD markup is sometimes
found in some VPlayer files. Also, generally speaking, the subtitles
text decoders have no use of these timings (and they must not use them
since it would break any user timing adjustment).

Technically, this is a major ABI break. In practice, a mismatching
lavf/lavc will now error out for MicroDVD decoding. Supporting both
formats requires unnecessary complex and fragile code.

FATE needs update because line breaks in the ASS file were "\n" (because
that's what is used in the original file). ASS format expect "\r\n" line
breaks; this commit fixes this issue. Also note that this "\r\n"
trailing need to be moved at some point from the decoders to the ASS
muxer.

This function can be useful for various other subtitles formats.

Both libavformat and libavcodec requires this function.

Note that the linebreaks text codec option (but not the feature) has
been removed; its main goal was to allow demuxers to configure the text
decoder (and not meant to be used by users), but the AVOption are not a
viable solution. This is solved differently in this commit.

This commit also makes sure the extradata and subtitle_header are NUL
terminated, without taking into account the trailing '\0' in account in
the size.

At the same time, it should fix 'warning: dereferencing type-punned
pointer will break strict-aliasing rules' warning for compilers who
don't consider uint8_t** and char** compatibles.

This is not necessary anymore since the last commit.

This breaks the sed in configure:find_things(). Fixes regression from
c73c87b. Fixes Ticket2079.

Some wav files report a data size that is bigger than the actual file size.
Fall back to estimation from bitrate in such cases.

It will overflow if somebody keeps streaming for a time long enough.

start_time is in stream timebase units while end_time is
in AV_TIME_BASE ones.

Consider the corner case with a list size larger than the wrap
number.

recording_time is in AV_TIME_BASE units.

Avoid calling av_get_frame_filename twice, once to generate the
segment filename and once to generate the playlist.

The segment path is desumed from the playlist path, recording a
relative path in the playlist while serving the file could lead
to misleading results.
