This patch is the same as 8a1714ad but
applied to encoding. It fixes the current clash of the -password option
between tta decoder and the icecast protocol.

  http: Reduce scope of a variable in parse_content_encoding()
Merged-by: Michael Niedermayer <michaelni@gmx.at>

The file does not require atomic.h. Also kills function redefinition warnings.

This avoids annoying warnings about unused functions. The compatibility
wrapper is designed to provide a complete (stub) API, so some functions
being unused by some files is natural and no reason for a warning.

Also fixes an unused variable warning with zlib disabled.

The issue is that, when the main packet data buffer is changed, streamcopy
uses a temporary new packet to store that buffer, frees the old packet, and
replace it with the new packet.

However, in doing so, it forgets about the side data, which gets freed, but
is still needed and referenced. Then, when the packet gets freed again in
the normal code path, it attempts to free its side data which has already
been freed.

Therefore, simply avoid the first free on side data by removing that side
data from the packet.

Fixes ticket #3773.
