Sparse fixes: NULL use, header order, ANSI prototypes, static
Fix Sparse warnings: * use NULL instead of plain 0 * rearrange header include order to avoid redefining types accidentally * ANSIfy SLIRP * avoid "restrict" keyword * add static git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6736 c046a42c-6fe2-441c-8c8c-71466251a162
