IPMI support on OpenBMC

[tomjose]

This mail is to solicit feedback on the IPMI implementation on OpenBMC 
and figure out if any important feature is missing.
We have added support for IPMI over network(standard IPMI port) and the 
BT transfer. The first milestone we are trying to
achieve is to have support for all the mandatory IPMI commands. Below is 
a snapshot of current situation based on feature
and command support.

Supported Features:
---------------------------

-> Chassis Commands
-> SEL
-> FRU command
-> Serial Over LAN
-> Watchdog support
-> Sensor commands
-> Network Configuration
-> Boot Configuration


Work in Progress & Pending stuff:
-------------------------------------------

-> Full fledged SDR support
-> DCMI Compliance
-> User Management commands

Following is the list of the supported IPMI commands:
