lvm2/tools/vgcreate.c
Dave Wysochanski 8868a4ffc2 Move more parameter validation into the library.
Update vgrename to call validate_vg_rename_params().
Fix vgcreate and vgsplit default arguments by adding defaults parameter to
fill_vg_create_params().
Add t-vgrename-usage.sh test.
Bugzilla: bz251992
