hls: Store first_timestamp in units of AV_TIME_BASE

When first_timestamp was stored as-is, its actual time base
wasn't known later in the seek function.

Additionally, the logic (from 795d9594cfa) for scaling it
based on stream_index is flawed - stream_index in the seek
function only specifies which stream the seek timestamp refers
to, but obviously doesn't say anything about which stream
first_timestamp belongs to.

In the cases where stream_index was >= 0 and all streams had the
same time base, this didn't matter in practice.

Seeking taking first_timestamp into account is problematic
when one variant is mpegts (with real timestamps) and one variant
is raw ADTS (with timestamps only being accumulated packet
duration), where the variants start at totally different timestamps.

hls: Store all durations in AV_TIME_BASE

Also parse segment durations as floating point, which is allowed
since HLS version 3.

This is based on a patch by Zhang Rui.

udp: Allow specifying multicast include/blocks as host names as well

Previously this only allowed literal IP addresses. When these
are conveyed in a SDP file as in RFC4570, host names are allowed
as well.

udp: Keep track of include and exclude sources separately

This allows us to explicitly fail if the caller tried to set
both inclusions and exclusions at the same time.

rtsp: Support RFC4570 (source specific multicast) more properly.

Add support for domain names, for multiple source addresses,
for exclusions, and for session level specification of addresses.

hls: Call avformat_find_stream_info() on the chained demuxers

This allows the chained demuxer (or more precisely, the lavf
utility code) to better fill in timestamps on packets from
these, especially for cases where one stream is a raw ADTS
stream.
