e19f005daf Upstream: content_length_n API change.
We no longer use r->headers_out.content_length_n as a primary source of
backend's response length.  Instead we parse response length to
u->headers_in.content_length_n and copy to r->headers_out.content_length_n
when needed.

360ed25d65 Upstream: separate pool for peer connections.
This is required to support persistent https connections as various ssl
structures are allocated from connection's pool.

c42c70f478 Workaround for cpu hog on errors with cached connections.
Just doing another connect isn't safe as peer.get() may expect peer.tries
to be strictly positive (this is the case e.g. with round robin with multiple
upstream servers).  Increment peer.tries to at least avoid cpu hog in
round robin balancer (with the patch alert will be seen instead).

This is not enough to fully address the problem though, hence TODO.  We
should be able to inform balancer that the error wasn't considered fatal
and it may make sense to retry the same peer.

d7c2673d3f API change: ngx_chain_update_chains() now requires pool.
The ngx_chain_update_chains() needs pool to free chain links used for buffers
with non-matching tags.  Providing one helps to reduce memory consumption
for long-lived requests.

a3741fb24d finalizing with rc == 0 in unbuffered proxy mode caused nginx to wait
for another send_timeout before actually closing client's connection
if client timed out while still talking to upstream server

406a68003c several changes in cache cleanup handling:
*) now ngx_http_file_cache_cleanup() uses ngx_http_file_cache_free()
*) ngx_http_file_cache_free() interface has been changed to accept r->cache
   ngx_http_file_cache_cleanup() must use r->cache, but not r, because
   there can be several r->cache's during request processing, r->cache may
   be NULL at request finalising, etc.
*) test if updating request does not complete correctly
