89f9f69e3f lavf: rescale duration for chained muxers.
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.

1c6477f30f Revert "lavf/utils: add support for special characters encoding in URL"
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

de9cd1b173 lavf: Handle the environment variable no_proxy more properly
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.
