reformat only (get rid of unnecessary block scope)

Clarify an existing requirement of the server_portstr parameter
to ap_proxy_determine_connection(): it must be a buffer of at
least one byte in size.

(And don't bother with using strcpy in order to zap a string.)

mod_cache: Preserve non-cacheable headers forwarded from an origin 304
           response. PR 55547.

When mod_cache asks for a revalidation of a stale entry and the origin responds
with a 304 (not that stale), the module strips the non-cacheable headers from
the origin response and merges the stale headers to update the cache.

The problem is that mod_cache won't forward the non-cacheable headers to the
client, for example if the 304 response contains both Set-Cookie and
'Cache-Control: no-cache="Set-Cookie"' headers, or CacheIgnoreHeaders is used.


mod_cache: follow up to r1591328.

Define the cache_merge_headers_out() function to merge r->err_headers_out into
r->headers_out and add the ones from r->content_type/encoding if available.
Use it in ap_cache_cacheable_headers_out() where the same is done and in
cache_save_filter() where this has to be done before updating the entry.


mod_cache: follow up to r1594643.

Avoid table lookup if not necessary (fast path first).

It does more than just a ProxyPass, but also looks at the HOST header,
so this gives somewhat deeper insight into what the end result looks
like.
