#5845: HLS does not honour HTTP multiple_requests option

----------------------------------+----------------------------------
 The HTTP protocol has a multiple_requests option. When this is enabled,
 HLS still creates a new HTTP connection for each URL it needs to fetch,
 including new DNS lookups. It should make use of keep-alive (persistent)
 connections. This results in unnecessary round-trips including TLS
 negotiation when the URLs are HTTPS ones.

 How to reproduce:
