[lvm-devel] [PATCH 3/7] Rename vg_change_pesize to vg_set_extent_size and use vg_t.

[Dave Wysochanski]

Rename vg_change_pesize to vg_set_extent_size and use vg_t.
In liblvm, we will reserve the word 'change' to mean an API that
both sets one or more values, and commits to disk.  This will be
consistent with the LVM commandline.  The existing vg_change_pesize()
function does not commit to disk, but just changes the extent_size
and ensures all internal structures are updated.  This logic should
be contained in a function that sets the value.
