Make the code compatible with c++ compiler

if we write "int i;" in header file, c compiler treats
as a tentative definition while c++ compiler
treats as a definition.
so when two cpp file includes the same header file
then during linking time compiler says that there are
multiple definitions.

so to overcome this problem we are declaring it as extern
and defining it in the corresponding c file.

MBOX

This repo contains the protocol definition for the host to BMC mailbox communication specification which can be found in Documentation/mbox_procotol.md.

There is also a reference implementation of a BMC mailbox daemon, the details of which can be found in Documentation/mboxd.md.

Finally there is also an implementation of a mailbox daemon control program, the details of which can be found in Documentation/mboxctl.md.
