only manipulate c->input_filters no matter what we pass. We need to make
copies of c->input_filters after, not before, it skips over reqtimeout.

Note: reqtimeout doesn't really interfere today with normal operation,
but this is misleading/confusing when dealing with other
wstunnel issues.

The immediate use is for a SSL-related module which works
on the backend proxy connection to be able to "leak" information
into the client r for logging.

This could be useful with other proxy scheme handlers.

Putting the vhost-level elements last allows overriding global settings
(for the deprecated SSLRequire directive, the order is irrelevant,
all of them must be met, cf. ssl_engine_kernel.c:ssl_hook_Access).

that might be set by filters.

The problem occurs when no body bytes were read while reading the
response headers, resulting in an empty brigade being sent down
the filter stack.  One particualr filter that mishandles the empty
initial brigade is mod_deflate.  It neglects to add to the response
header fields.

Since r1585609 the quoted syntax is ok, but it won't be as efficient so we
probably shouldn't put that syntax in the documentation.
