When a file appears to start with a id3 tag and appears to
also be something else, then try to increase the probe buffer
size if its below its limit.

To avoid allocating ridiculous amounts of memory for corrupted files,
read the input in chunks limited to filesize or an arbitrary large
amount when that is not known (chosen to be 50M).

Fix trac ticket #2300 because the duration of the segments
was computed using the timestamp of the last packet plus its
duration using the 1/90000 default time base instead of using
the chained muxer time base.

This reverts commit 4a8fc1d83b.

The commit caused null pointer derefernces when using udp://
after i fixed that it caused ffmpeg to get stuck and remapped
arguments like ?ttl=255 -> ?ttl%3d255

I dont want to leave this broken thus temporary revert so we all
have some time to look at this without half the network protocols
being broken in the meantime

In particular, fix trac ticket #2031.

The handling of the environment variable no_proxy, present since
one of the initial commits (de6d9b6404), is inconsistent with
how many other applications and libraries interpret this
variable. Its bare presence does not indicate that the use of
proxies should be skipped, but it is some sort of pattern for
hosts that does not need using a proxy (e.g. for a local network).

As investigated by Rudolf Polzer, different libraries handle this
in different ways, some supporting IP address masks, some supporting
arbitrary globbing using *, some just checking that the pattern matches
the end of the hostname without regard for whether it actually is
the right domain or a domain that ends in the same string.

This simple logic should be pretty similar to the logic used by
lynx and curl.

Log message in case the max_probe_size value in av_probe_input_buffer()
is smaller than the minimum accepted value.

av_codec_get_tag() may return 0 both in case a codec_tag was
found and if no codec_tag was found.
The new function does not have this ambiguity.

In particular, specify the unit of the shown values in case the max probe
