Hrm, it seems to be OK by the end of the series, in that it built for me
before push and has passed smoke-test. So I may have introduced a bisection
hazard (sorry) but it's too late to fix that unfortunately.

Various of the tools/libs/*/include/*.h have a

    /* Callers who don't care don't need to #include <xentoollog.h> */
    typedef struct xentoollog_logger xentoollog_logger;

but since that typedef matches in all cases I think it is allowed to be
repeated like this, isn't it?

Ian.
