I do not think we want function scope static state anywhere in the cascade
filter chain, as it will forbid us from running more than one output chain
at the same time in the future. I think the correct way to structure it
would be to create lf_to_crlf_filter as a proper subclass of stream_filter
(see how cascade_filter_fn() casts its filter argument down to an instance
of the cascade_filter class and uses it to keep track of its state) and
keep this variable as its own filter state [*1*].
[Footnote]
*1* We currently use a singleton instance of lf_to_crlf_filter object
because the implementation assumed there is no need for per-instance
state.
