[PATCH] SPDY/3.1 protocol implementation

[Valentin V. Bartenev]

http://nginx.org/patches/patch.spdy-v31.txt

This patch upgrades implementation of SPDY protocol in the 
ngx_http_spdy_module from draft 2 to draft 3.1.

I am going to commit it at the end of this week. Till then,
testing, review and suggestions are very much appreciated.

How-to for newbies:

 1) Make sure that you have OpenSSL 1.0.1 or later.

 2) Download nginx/1.5.9:

 % wget http://nginx.org/download/nginx-1.5.9.tar.gz

 3) Unpack it:

 % tar xvfz nginx-1.5.9.tar.gz
 % cd nginx-1.5.9

 4) Download and apply the patch:

 % wget http://nginx.org/patches/patch.spdy-v31.txt
 % patch -p1 < patch.spdy-v31.txt

 5) Configure and build nginx:

 % ./configure --with-http_ssl_module --with-http_spdy_module
 % make

 Hint: have a look at http://nginx.org/en/docs/configure.html
 and try "./configure --help" for more useful options.

If you are already using spdy/2, then no configuration changes
are required. Otherwise, please check the documentation:
http://nginx.org/en/docs/http/ngx_http_spdy_module.html

Thanks for testing.
