The parsing of .m3u8 HLS files was too position dependend and did not work well
with some implementations of HLS playlist files. Parsing and reading the .m3u8 file
are now separated.

Functions to read an entire M3U8 meta or playlist file from the HLS server into a buffer.
The buffer will be parsed later.

If downloading of a segment takes longer then its duration, then print
a warning instead of terminating playback.

When there is less then 3 times the target duration of data available in
the HLS stream print a warning and try to start anyway. Instead of aborting
playback. Other HLS clients seem to do the same.

Improve detection of HTTP Live Streaming detection to all EXT-X tags.

Do not start live playback when there is not enough data available. There
should at least be 3 times the target duration of data segments.

The httplive stream_filter ignored HTTP port numbers other then 80 and 443.
These where dectected by HTTP access input. Other port numbers were simply
ignored.
The patch now uses the original portnumber and carries it along when
handling relative_URI() and download URI in AccessOpen() functions.

This reverts commit 01dbb084.

I must have had something really wrong going on in scratchbox for this
commit to fix things.

Untested

This simplifies memory handling in most cases.

The attribute name is valid until the next attribute or next node.
This simplifies the code a bit: fewer error paths, and free() calls.

A few potential memory leaks were fixed too.

Rename preferences entries, put in the right categories, etc...

This is used in a very particular situation
(language code changing continuously on a single PID, signaled by a
change in teletext data), but maybe other uses can be inspired from it.
