[Qemu-devel] [PATCH] fix various compiler warnings

[Jan Kiszka]

This belongs into the category "mostly harmless", but it is still
annoying when you change core headers and look out for build
regressions. Some spots still remain (namely in slirp), but it is a
start. Please cross-check if all the silencing is actually valid and not
papering over a real issue (but it doesn't appear to me)!
