Add liblvm test case for creating of a vg.

Browse Source 
liblvm unit test case uses the following APIs:
- lvm_create, lvm_destroy
- lvm_vg_create, lvm_vg_extend, lvm_vg_set_extent_size, lvm_vg_write,
lvm_vg_remove, lvm_vg_close

Version 2.02.49 -
================================
Add unit test case for liblvm VG create/delete APIs.
Add liblvm APIs to implement creation and deletion of VGs.
Initialize cmd->cmd_line to "liblvm".
Place handles to liblvm objects for pv, vg, lv, lvseg, pvseg inside lvm.h
Refactor vgsplit and vgextend to remove READ_REQUIRE_RESIZEABLE flag.
Changed exit() to _exit() after fork(); avoid flushing libc buffers twice.
Fixed invalid type being passed as printf argument on Sparc64.
