Fix view-source dpi to handle null characters correctly

Although not allowed in text contexts, null characters should not
stop/halt/fail dpi protocol, thus the patch.

Test Example. Display a file with these contents:

 null padding^@^@

(two trailing null characters)
and view source for it.

Note that dillo will not _display_ the file completely correct,
it will eat a char after each null, but this is not a problem in
dpi nor dpip but in rendering, the cache gets it right.

Adding code to correctly _display_ these anomalous pages is probably
not worth the effort though.
