[PATCH 0/3] another round of proxy_pass fixes

[Eric Wong <e@80x24.org>]

I really hope this will be the last round of critical fixes :)

Stress-tested numerous times on a yet-to-be-public 800M+ git
repo over dumb HTTP cloning:

	GIT_SMART_HTTP=0 git clone (client)
	|
	v
	yahns HTTP/HTTPS proxy_pass(proxy_buffering: false)
	|
	v
	varnish 4.0.2 (random chunks results,
		       even given Content-Length :p)
	|
	v
	static file server (with some dynamic parts)

Eric Wong (3):
      proxy_pass: avoid TOCTTOU race when unbuffering, too
      proxy_pass: avoid accessing logger in env after hijacking
      proxy_pass: avoid stuck responses in "proxy_buffering: false"

P.S. and git dumb HTTP cloning could probably be better about
memory/CPU usage...
