Re: [PATCH v2 0/6] add post parse pSeries mem align, when ABI_UPDATE

Hi, This is a follow up of [1] after really comprehending what I was messing with and what I couldn't do. This version has a shorter scope, only pSeries guests are being taken care of. I can send a follow up to handle x86 as well depending on the popularity of this work. Patches 1 and 2 moves the existing qemuDomainAlignMemorySizes() from qemu_command.c to qemuProcessPrepareDomain(). They are not related/tied to everything else done here and can be pushed independently if needed. Patches 3, 4 and 5 are reworking the existing code to be consistent to our prerrogative of not aligning memory when migrating or 'snapshotting'. No significant behavioral change is done. Patch 6 is where the bacon is. For new ppc64 guests, without ABI breakage, the mem alignment that are overshooting the intended initial memory is fixed. Test cases were added to help me diagnose and assert what I was changing and what would remain untouched.
