Invalid data found for live audio stream

This looks like a regression, as it works with 1.1.1 release. This is on the latest git (this morning).

Command line:
ffmpeg -v 99 -loglevel 99 -i ​http://69.166.45.47:8000 -report

Regression since 1fabd95 - related to ticket #2265, I liked the commit very much, but it apparently has to be reverted;-(
Work-around is to use -user-agent:

$ ffmpeg -user-agent 42 -i http://69.166.45.47:8000

Feel free to revert. It is also known to break playback on http streaming server who use the user agent to guess if it's a browser (to display a summary) or a player (to stream the audio data).

Note: if you revert, please keep the default user agent string in the options tab (and thus keep http_connect unchanged); basically, just remove "Mozilla/5.0" from DEFAULT_USER_AGENT.
