Re: [Libvir] PATCH 9/20: unify the two buffer implemenations



This patch moves the previously created qemud/buf.c file into the src/
directory and deletes the original implementation in src/xml.c. The
qemud/Makefile.am is hacked to compile the code from src/buf.c directly.
This hack will go away in a later patch.
