I haven't quite got to my goal of removing _GNU_SOURCE (yet), but this patch along the way creates a lib/ subdirectory and moves the common buffer code (from qemud/buf.[ch] and in src/xml.[ch]) there. There are many, many places which call the buffer functions without checking the return value. I have manually verified / fixed up the calls which do bother to check return values, but not added any more checks where they don't.
