c864c3968a segment: Add an option for omitting the first header and final trailer
This allows writing totally bare segments, without any header/trailer
included anywhere.

a854362b40 segment: Flush buffered data before finishing a segment
This makes sure any buffered data is written to the segment, for
muxers that buffer up data internally (e.g. fragmented mp4).

f7b240434c segment: Set the resend_headers flag for each segment
This makes sure new inline headers are emitted when the next
packet is written. This allows segmenting mpegts without calling
write_header/write_trailer (nor freeing/reiniting the muxer)
for each segment.

378a6315b7 segment: Add an option for disabling writing of a header/trailer to each segment
Some segmented formats (such as fragmented mp4) are "bare", as in,
the segment files do not have the same headers/trailers as full normal
files of that format have.

eb447d5159 segment: Free and reinit the muxer before calling avformat_write_header
This makes sure the muxers are set up in the way they expect
with no data left around from the previous run (which could
cause various issues including memory leaks, depending on the chaine
muxer).

This fixes memory leaks with the mpegts and flv muxers. It also
makes the usage of chained muxers correct.

73871dc96f segment: Use the public av_write_header/av_write_trailer functions
With this change, the segmenter muxer doesn't rely on anything
not available/supported to libavformat external users, making
the segmenter muxer do things just like a normal segmenter
application using libavformat would do.

0edae4e628 segment: Properly create new AVStreams for the chained muxer
Before, the chained muxer reused the AVStreams array from
the outer muxer, which made it impossible to use the proper
public functions (such as av_write_frame) when calling the
chained muxer.

4edb34f6cc segment: Pass the interrupt callback on to the chained AVFormatContext, too
This might not be needed at the moment, but it's good practice to
pass it to all chained AVFormatContexts, if it would happen to be
used there at a later point.

8bd324e9e4 http: Increase buffer sizes to cope with longer URIs
Use the MAX_URL_SIZE define where applicable. Increase buffer
sizes for all buffers that need to fit a long pathname - buffers
that need to fit only the hostname (and other short strings, but
not the pathname - such as "headers" in http_connect) are kept
at 1024 bytes for now.

Also increase the max line length in http_read_header, since it
might need to contain a full url for Location: redirects.
