Trigger a refill if the seek action moves the pointer
at the end of the buffer.

Before this patch the read action following the seek would trigger
the refill, while write action would write outside the buffer.

In the Libav codebase few muxers seek forward outside of what
already has been written so it is quite unlikely to experience
the problem with the default buffer size.

It seems more logical and works with more restricted C compilers
like tinycc.

Quite a few programs missed that detail of the spec
(including old versions of FFmpeg I believe) and when
we would otherwise fail anyway it seems worth a try
to use a simple byte-aligned stride instead.
