It has been deprecated some time ago, but was forgotten during the last
bump.

This avoids cases where configure tries to weakly enable an item
which actually is disabled, ending up still enabling dependencies
of the item which itself is only enabled weakly.

More concretely, the h264 decoder suggests error resilience, which
is then enabled weakly (unless manually disabled). Previously,
dsputil, which is a dependency of error resilience, was enabled
even if error resilience wasn't enabled in the end.

The variable name 'var' is commonly used to iterate through arguments
in other functions. When the pushvar function internally uses the
variable 'var', it makes pushing/popping the variable 'var' not
work as intended.

The function does not do any rounding, so there is no point in
keeping it in a round template file.

The function is only instantiated once, so there is no point
in keeping it in a template file.

Explicitly saying it can't hurt.

Now that the headers themselves have ifdef protection this is no
longer necessary and more consistent with normal include handling.

This prevents non-AltiVec-enabled compilers from choking.

This makes output -ss sample-accurate for audio and will allow further
simplication in the future.

This makes -t sample-accurate for audio and will allow further
simplication in the future.

Most of the FATE changes are due to audio now being sample accurate. In
some cases a video frame was incorrectly passed with the old code, while
its was over the limit.

This way OutputFile variables like recording time can be used when
creating the streams.

Options are freed from the generic code now, there is no need to call
av_opt_free() from the filter.

It now allows an arbitrary number of inputs, not just two.

Otherwise some code might mistakenly think it is allowed to unref those
buffers, which would lead to double unref.

It is a part of the sample that got broken by recent indeo3 changes.

They are the same in this case, except put_pixels also has blocksizes
smaller than 8.
