c2cb01d418 lavf: introduce AVFMT_TS_NEGATIVE 
Most formats do not support negative timestamps, shift them to avoid
unexpected behaviour and a number of bad crashes.

59220d559b oggenc: add a page_duration option and deprecate the pagesize option 
This uses page duration instead of byte size to determine when to buffer
the page. Also, it tries to avoid continued pages by buffering the current
page if there are already packets in the page and adding the next packet
would require it to be continued on a new page. This can improve seeking
performance.

The default page duration is 1 second, which is much saner than filling
all page segments by default.

10b1c060f9 oggenc: fix condition when not to flush due to keyframe granule. 
The previous condition of 0 page size was wrong,
that would disable the mechanism for all frames at
a start of a page, thus some keyframes still would not
get their own granule.
The real problem is that header packets must not be flushed,
but they have (and must have) 0 granule and thus would
be detected as keyframes.
Add a separate parameter to mark header packets.

ed3e1b485a oggenc: add pagesize option to set preferred page size 
When set, if an Ogg stream buffer has enough data, a page is made
instead of filling maximum-size pages. Using smaller pages results
smaller seek intervals at the expense of higher container overhead.

avpriv_split_xiph_headers() is replaced by a buffer that must be freed

c6610a216e Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. 
This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.
