[libvirt] [PATCH 0/2] avoid getpwuid_r deadlock

[Eric Blake]

https://bugzilla.redhat.com/show_bug.cgi?id=964358

Posting now to get reviews started.  I'd especially like to get
feedback that it doesn't break LXC, and that it works with root-squash
NFS when using qemu:qemu instead of root:root in /etc/libvirt/qemu.conf.
I hope to do more testing myself, and also see if I can try writing an
LD_PRELOAD shim as part of 'make check' to make it easier to test that
the right system calls are made during the sequence.
