lsirec: init at unstable-2019-03-03

This adds lsirec, a utility that can be used to modify and recover certain LSI HBA PCIe cards.
My Dell R610 Server has an anti-feature that prevents the machine from booting, if any PCIe card not blessed by Dell for such usage is installed in the "storage slot" of the server. I used lsiutil to flash a different firmware to my "Dell PERC H310" to convert it into a "Dell 6Gbps SAS HBA Adapter". I was then able to use lsirec and the included sbrtool python script to modify my "Dell 6Gbps SAS HBA Adapter" card into pretending to be a "Dell PERC H200 Integrated" card, finally making it work in the storage slot and circumventing the stupid firmware check.
