This allows setting/overriding e.g. the bitrate parameter, which
is required for the smoothstreaming muxer. Normally, the bitrate
is set by the demuxer in these cases, but not all demuxers can
provide it. This allows stream copy of data to the smoothstreaming
muxer from such inputs.

In this case, no encoder specific options are filtered, only
options specific to that codec type in general.

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.

The external assembly function uses mmxext instructions and should not be
masqueraded as an mmx-only function. Instead, use the mmx-only inline
assembly function.
The specification does not prevent an encoder to write the amplitude 0
as 0 amplitude_bits.
Our get_bits() implementation might not support a zero sized read
properly, thus the additional branch.
The value is used to calculate output LSP curve and a division by zero
and out of array accesses would occur.

The init functions marked as av_cold have to be executed in any case,
so there is no gain from trying to mark paths leading to such functions
as unlikely.
This also allows libx264 to modify its i_qfactor value
when using the "-tune" setting. Previously it had a static
value of 1.25
