Nothing in defs.h actually uses this. Add some includes for some spots using things from hashtab.h. Note that if the GDB build doesn't use libxxhash, hashtab.h is included by gdbsupport/common-utils.h, so all files still see hashtab.h. It puzzled me for some time why I didn't see build failures in my build (which didn't use libxxhash) but the buildbot gave build failures (it uses libxxhash).
