Upstream: fixed proxy_no_cache when caching errors.
Caching errors, notably intercepted errors and internally generated
502/504 errors, as well as handling of cache revalidation with 304,
did not take into account u->conf->no_cache predicates configured.
As a result, an error might be cached even if configuration explicitly
says not to. Fix is to check u->conf->no_cache in these cases.
To simplify usage in multiple places, checking u->conf->no_cache is now
done in a separate function. As a minor optimization, u->conf->no_cache
is only checked if u->cacheable is set.
As a side effect, this change also fixes caching errors after
proxy_cache_bypass. Also, during cache revalidation u->cacheable is
now tested, so 304 responses which disable caching won't extend
cacheability of stored responses.
Additionally, when caching internally generated 502/504 errors
u->cacheable is now explicitly updated from u->headers_in.no_cache and
u->headers_in.expired, restoring the behaviour before 8041:0784ab86ad08
(1.23.0) when an error happens while reading the response headers.
