Add struct spdk_bdevperf and include header of io_target_group list
in it, and then allocate its global instance g_bdevperf statically.
Rename g_head by groups for clarification.
The next patch will register g_bdevperf as SPDK IO device and
allocate io_target_group as context of the corresponding IO channel.
