stream_lavf: use ffmpeg for http/https streaming 

The internal mplayer http implementation is terrible and old. Try to use
ffmpeg instead. Enable ffmpeg https as well (we don't have native
support for it and never will).

Enable the cache for ffmpeg streams. In theory, we want to enable the
cache for network streams only (or at least, not enable it for files),
but there doesn't seem to be any way to query this. ffmpeg has its own
read-cache, but apparently it doesn't get filled asynchronously (only
to the degree internal socket/kernel buffers do).

Should it turn out that the mplayer implementation is better than
ffmpeg's in some way (unlikely), this commit might be reverted until
ffmpeg is ready. So far, the ffmpeg implementation seems to work very
well though.

The original mplayer stream implementation is made available under
"mp_http://" and "mp_http_proxy://". This is for testing, until the
http implementation is completely removed. Note that this is unlikely
to happen soon: ffmpeg doesn't support Microsoft streaming, while
mplayer has some support. This code has dependencies on http.

Note: "http_proxy://" doesn't work anymore. Use "httpproxy://" to get
the ffmpeg implementation of it.

Using https requires enabling OpenSSL in ffmpeg by adding
the --enable-openssl switch to ffmpeg's configure.
