Updated to nginx 1.9.5

Changes from 1.9.4

*) Feature: the ngx_http_v2_module (replaces ngx_http_spdy_module).
   Thanks to Dropbox and Automattic for sponsoring this work.

*) Change: now the "output_buffers" directive uses two buffers by
   default.

*) Change: now nginx limits subrequests recursion, not simultaneous
   subrequests.

*) Change: now nginx checks the whole cache key when returning a
   response from cache.
   Thanks to Gena Makhomed and Sergey Brester.

*) Bugfix: "header already sent" alerts might appear in logs when using
   cache; the bug had appeared in 1.7.5.

*) Bugfix: "writev() failed (4: Interrupted system call)" errors might
   appear in logs when using CephFS and the "timer_resolution" directive
   on Linux.

*) Bugfix: in invalid configurations handling.
   Thanks to Markus Linnala.

*) Bugfix: a segmentation fault occurred in a worker process if the
   "sub_filter" directive was used at http level; the bug had appeared
   in 1.9.4.

Updated naxsi to 0.54

From 0.53-2 "AppleJack":

* increased PCRE output vector from 6 to 30 (from 2 match groups to 10)
* removed negative rule on content-types (naxsi_core.rules) as naxsi supports
  json
* Fixed broken EXLOG on |NAME match zones (issues/110)
* Integrated libinjection (xss/sqli)
