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.

It is behaving a little bit different from the libxml parser which has
caused weird bugs in the past. Anyway, everybody has libxml (I am
planning to write an Expat parser too but not there yet).
