 Summary of the bug:

 There is a problem when trying to play an m3u8 (HLS) playlist
 that requires cookies to be sent. Specifically, when the
 server sets cookies that are valid for all sub-domains but
 the URL to be played is of the top-level domain.
 For example:

 domain in URL: bar.com/segments.m3u8
 Cookie set domain: .bar.com
 (leading dot in cookie cdomain = valid for all sub-domains
 AND the master domain).

 The bug is in http.c get_cookies function, when matching
 the domain.

 There are 3 scenarios with cookies:

 1. Specific domain set by cookie. i.e: foo.bar.com - WORKS.
 2. Cookie specifies sub-domain and the URL to play is in a
 sub-domain. i.e: URL points to foo.bar.com, cookie sets .bar.com - WORKS.
 3. Cookie specifies sub-domain and the URL to play is at the
 master domain level. i.e: URL is bar.com, cookie sets .bar.com - NOT
 WORKING.

 May be related to #2180.

 I want to note I have a working fix for this. I'm using
 libavformat from within XBMC. I fixed http.c and compiled
 ffmpeg's libs and it works.

 XBMC 13.0 Gotham uses ffmpeg 1.2 but the code hasn't changed
 at all in newer versions.
 (how do I submit a patch?)
