Log Message:
Update www/nginx to 1.10.1.
Update 3rd party modules in options.mk.

Changes with nginx 1.10.1

- Security: a segmentation fault might occur in a worker process while
  writing a specially crafted request body to a temporary file
  (CVE-2016-4450); the bug had appeared in 1.3.9.

Changes with nginx 1.10.0

- 1.10.x stable branch.

Changes with nginx 1.9.15

- Bugfix: "recv() failed" errors might occur when using HHVM as a
  FastCGI server.

  directives a timeout or a "client violated flow control" error might
  occur while reading client request body; the bug had appeared in
  1.9.14.

  was used and client request body was not fully read; the bug had
  appeared in 1.9.14.

  directive.
  Thanks to Mindaugas Rasiukevicius.

Changes with nginx 1.9.14

- Feature: OpenSSL 1.1.0 compatibility.

- Feature: the "proxy_request_buffering", \ 
"fastcgi_request_buffering",

Changes with nginx 1.9.13

- Change: non-idempotent requests (POST, LOCK, PATCH) are no longer
  passed to the next server by default if a request has been sent to a
  backend; the "non_idempotent" parameter of the \ 
"proxy_next_upstream"
  directive explicitly allows retrying such requests.

- Feature: the ngx_http_perl_module can be built dynamically.

- Feature: UDP support in the stream module.

- Feature: the "aio_write" directive.

- Feature: now cache manager monitors number of elements in caches and
  tries to avoid cache keys zone overflows.

might
  appear in logs when using the "sendfile" and "aio" \ 
directives with
  subrequests.

  caching was used and a client closed a connection prematurely.

  caching was used.
  Thanks to Justin Li.

  "uwsgi_pass" directives when using variables.
  Thanks to Piotr Sikora.

  cause segmentation fault in a worker process (CVE-2016-0742).

- Security: use-after-free condition might occur during CNAME response
  processing if the "resolver" directive was used, allowing an attacker
  who is able to trigger name resolution to cause segmentation fault in
  a worker process, or might have potential other impact
  (CVE-2016-0746).

- Security: CNAME resolution was insufficiently limited if the
  "resolver" directive was used, allowing an attacker who is able to
