This properly handles pre-skip, seeking pre-roll, and end-trim. It
uses the i_nb_samples field of block_t to signal to the decoder how
many samples should be returned after (possibly) skipping some at
the start of the block (for both pre-skip and pre-roll). In
addition, it abuses the i_length field of block_t to signal to the
decoder how many samples to trim from the end of the packet (for
end-trimming).

This patch does not compute correct timestamps for streams which
start at a non-zero offset (e.g., live streams joined in the
middle), nor does it correctly compute the length of a stream. But
neither of those things work for Vorbis, either. I'm leaving them
for a follow-up patch.

If --no-sout-file-overwrite is specified, the access output will refuse
to overwrite an existing file. Overwrite is enabled by default for
backward compatibility with existing command lines.

While less precise, ticks count should be more stable than performance
counters.

We do not use (non-standard) alloca() anymore.

macosx: fixed conditionals for the different OS X release by adapting to the newly updated version defines

No functional changes.

WIN32 is defined also on WinCE anyway.

On OS X, fontconfig searches font only from /System/Library/Fonts, so this patch adds more search paths to its initialization.
