bug#4896: DocView: Continuous mode

[Juri Linkov <juri@jurta.org>]

I tried to add a menu item for `doc-view-continuous-mode' with
the following patch, but it doesn't look nice since currently
`doc-view-continuous-mode' is a variable.

If there are problems with that, maybe we should create a minor mode?
However, Continuous mode as a minor mode would complicate interactions
with another minor mode `doc-view-minor-mode' with questions like
should `C-c C-c' disable `doc-view-continuous-mode' and should another
`C-c C-c' re-enable it, and so on?
