  Rationale for Update:
  
  A longer term goal of the Server Team is to have NGINX 1.10.x (the next
  stable release of NGINX) in Ubuntu Xenial, either as a post-Xenial-
  release SRU, or right before we release, depending on when NGINX
  releases the 1.10.x branch (which is based off the 1.9.x branch).
  
  To reduce the delta between merges, and to reduce the amount of work
  necessary to switch from 1.9.x to 1.10.x in the future of Xenial, it is
  more preferable to have the latest 1.9.x available as close to 1.10.x
  release as possible; this makes it much more easier to deal with build
  failures, or to troubleshoot issues between versions, as there is less
  of an upstream delta.
  
  We do not enable HTTP/2, therefore the only feature change we should be
  worried about here is the ability of the `worker_cpu_affinity` directive
  being able to support more than 64 CPUs.  This does not affect other
  functionality.
  
  We have other bugfixes, as well, for other functions in the system,
  including 'add_header' directives, and incorrect logging of invalid
  headers.  These do not affect any of the other features in Ubuntu, nor
  does this appear to affect the feature-set of NGINX.

  Security Considerations:
  
  HTTP/2
  ------
  * HTTP/2 is disabled in the NGINX builds currently.  This is at the request of the Security Team.  There is no security concern of HTTP/2 in this release.
