  add -d option for dog cluster info

Dog cluster info with option -d just outputs the changed nodes
between the two adjacent epoches. It's useful in a cluster with
a large amount of nodes. And it would be a way easier to create
a nagios/icinga script that advertises you when something changes
in the cluster and what has changed.

  initial accelio support

This patch adds a support of accelio, an library of RPC which wraps
TCP and RDMA in clean way, to sheepdog. With this change, sheepdog
will be able to utilize high speed interconnect like infiniband.

The code is very early stage and have bunch of ToDos. However, I'd
like to share it and want the community to help the implementation.

How to build:
 1. install accelio
 2. ./configure --enable-accelio
 3. make

How to use:
 $ sheep -i transport=rdma,addr=xxx,port=yyy ...

Minor ToDos:
 - clean up code (e.g. comment out)
 - remove known segfault bugs
 - sane error handling
 - remove memory leaks

Major ToDos:
 - enhance code for utilizing RDMA
 - rx/tx in worker threads (I'm not sure it is effective because RDMA
   helps to reduce CPU consumption)
