Phyp still had several memory leaks and in general some bad
copy-and-paste design. This series consolidates some common
patterns into simpler helpers, avoiding leaks in the process.
Eric Blake (4):
phyp: prefer memcpy over memmove when legal
phyp: avoid memory leaks in return values
phyp: avoid memory leaks in command values
phyp: another simplification

New subject: [libvirt] [PATCH 1/4] phyp: prefer memcpy over memmove when legal
* src/phyp/phyp_driver.c (phypUUIDTable_AddLpar)
(phypGetLparUUID, phypGetStoragePoolUUID, phypVolumeGetXMLDesc)
(phypGetStoragePoolXMLDesc): Use faster method.
---
memmove is only required for overlapping regions; none of these
instances could overlap and memcpy is theoretically faster

New subject: [libvirt] [PATCH 4/4] phyp: another simplification
Rather than copying and pasting lots of code, factor it into a
single helper function.
* src/phyp/phyp_driver.c (phypExecInt): New function.
(phypGetVIOSPartitionID, phypNumDomainsGeneric, phypGetLparID)
(phypGetLparMem, phypGetLparCPUGeneric, phypGetRemoteSlot)
(phypGetVIOSNextSlotNumber, phypAttachDevice)
(phypGetStoragePoolSize, phypStoragePoolNumOfVolumes)
(phypNumOfStoragePools, phypInterfaceDestroy)
(phypInterfaceDefineXML, phypInterfaceLookupByName)
(phypInterfaceIsActive, phypNumOfInterfaces): Use it.

Serves me right for thinking Matthias' cleanups had already been
applied. Now I get to rebase, with lots of conflicts :)

Sorry for that :(
I'm currently quite busy with my studies and can only spent some time
on weekends for libvirt development to get some distraction. This
results in longer delays between libvirt related things I do. Today, I
successfully took an exam and am relaxing with libvirt stuff right
now.
You probably want to post a rebased v2 before I review your phyp
patches, don't you?

No problem. The fault is mostly mine for seeing your series and its
review, and assuming it was in without verifying it myself. :)

Yep, and v2 will be larger because I've found more leaks in the
meantime. Plus, your 2/5 missed cleaning up the error paths for all the
new interface functions that I just pushed in between when you submitted
your patches for review vs. actually pushing them, so I'm fixing those
to be consistent, as well.
