Evgeniy Polyakov 12003375ac [PATCH] w1: Userspace communication protocol over connector.
There are three types of messages between w1 core and userspace:
1. Events. They are generated each time new master or slave device found
	either due to automatic or requested search.
2. Userspace commands. Includes read/write and search/alarm search comamnds.
3. Replies to userspace commands.
