Add thin and thin pool lv creation support to lvm library
This is Mohan's thinp patch, re-worked to include suggestions
from Zdenek and Mohan.
V2: Remove const lvm_lv_params_create_thin
Add const lvm_lv_params_skip_zero_get
V3: Changed get/set to use generic functions like current
property
V4: Corrected macro in properties.c
V5: Fixed a bug in liblvm/lvm_lv.c function lvm_lv_create.
incorrectly used pool instead of lv_name when doing the
find_lv_in_vg call.
Based on work done by M. Mohan Kumar <mohan@in.ibm.com>
