Add insert_buckets support for OVS group (#36)

In Openflow 1.5, insert_buckets is supported. This PR adds
insert_buckets command when generating OVS group mod message,
and the buckets will be inserted after the current bucket list
since `command_bucket_id` is `OFPG_BUCKET_LAST`.

Fix bugs when Controller reconnecting to Switch (#31)

1. Maintain a variable for Switch connection, and close the previous
   one when reconnecting to Switch. This can ensure only one unix
   socket is used between Controller and Switch.
2. Add timeout when sending message to Switch or waiting for message
   from Switch, to avoid Controller entering blocking state in a long
   time.
3. Remove a duplicated SwitchFeatures request, and send SwitchConfig
   and Controller setting message when switch is connected.
4. Resolve OpenFlow version misconfiguration bugs in Hello message,
   and PortModification message.

Support arbitary bitwise register mask (#20)

For NXReg, OvS will accept value/mask on arbitary bitwise. If using
range[start:end], it is hard to combine discontinuous value/mask,
such as, to merge reg0[0:0] with reg0[2:2], with range method,
we will pass NXRange[0:2] and it will generate mask 0x7, but actually,
the mask is 0x5.

In this patch, we change merge function to support discontinuous mask
according to each reg piece range and then merge all pieces for one register.
