    run-command: support custom fd-set in async

    kusma committed with gitster
    This patch adds the possibility to supply a set of non-0 file
    descriptors for async process communication instead of the
    default-created pipe.
    Additionally, we now support bi-directional communiction with the
    async procedure, by giving the async function both read and write
    file descriptors.
    To retain compatiblity and similar "API feel" with start_command,
    we require start_async callers to set .out = -1 to get a readable
    file descriptor.  If either of .in or .out is 0, we supply no file
    descriptor to the async process.
    [sp: Note: Erik started this patch, and a huge bulk of it is
         his work.  All bugs were introduced later by Shawn.]
