Fix vndcompress restart failure fallback when input is a pipe.
...
Defer seeking the *input* image, or winding it forward, until we are
certain we all ready in the cloop2 output, because when the input
image is a pipe, we don't get a chance to seek back to the beginning
and start from the top instead of restarting.
If restart does fail, don't try to seek the input image back to the
beginning unless we had already tried to seek or wind it forward.
Add some automatic tests for this and related cases.

Change vndcompress to use a default window size of 512.
...
For vnduncompress on nonseekable input, the window size is as large
as it needs to be by default, as before. Not clear that this is the
right choice -- by default vnduncompress on nonseekable input will
just use unbounded memory unsolicited.

Perhaps vndcompress and vnduncompress ought by default to choose a
limited window size (say, 8192 entries, i.e. 64k bytes, the default
MAXPHYS), and vnduncompress should fall back to an unlimited window
only if the input is nonseekable.
