[PATCH] [Target_Core_Mod/ALUA]: Add group membership structure logic

[Nicholas A. Bellinger]

Greetings all,

This patch series adds proper ALUA Logical Unit Group and Target Port Group membership
association to Target_Core_Mod/ConfigFS in a manner that can handle concurrent shutdown from
core/$HBA/$DEV/ <-> core/alua/lu_gps/$MY_LUN_GROUP and core/alua/tg_pt_gps/$MY_TG_PT_GROUP <->
$FABRIC_MOD/target_port/lun/$LUN/alua_tg_pt_gp.

This infrastructure is used as explict and implict ALUA group operations continue to come
online for Target_Core_Mod/ConfigFS v3.0.  This patch is made against lio-core-2.6.git/master
and tested on v2.6.29-rc2 x86 32-bit HVM.  The lio-core-2.6.git tree can be found at:
