Update to latest stable release, 1.6.0. This folds many (but not all)
features from the previous development branch (1.5.x) - including various
SSL improvements, SPDY 3.1 support, cache revalidation with conditional
requests, auth request module and more. Resolves CVE-2013-4547.
files/nginx.sh now has a configtest command for lazy admins (me) who don't
want to remember command line options. CHANGELOG:
