[Libvir] [PATCH] libvirt.c: warning: dereferencing type-punned pointer will break strict-aliasing rules

I'm currently trying to get libvirt to compile with -Werror. One problem which came up early is the warning in $SUBJECT. The gcc info page (see -fstrict-aliasing) is pretty unclear about what exactly causes this problem, so the attached patch rewrites the code quite conservatively to avoid the problem.
