Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:

    credit1: on vCPU wakeup, kick away current only if makes sense
    
    In fact, when waking up a vCPU, __runq_tickle() is called
    to allow the new vCPU to run on a pCPU (which one, depends
    on the relationship between the priority of the new vCPU,
    and the ones of the vCPUs that are already running).
    
    If there is no idle processor on which the new vCPU can
    run (e.g., because of pinning/affinity), we try to migrate
    away the vCPU that is currently running on the new vCPU's
    processor (i.e., the processor on which the vCPU is waking
    up).
    
    Now, trying to migrate a vCPU has the effect of pushing it
    through a
    
     running --> offline --> runnable
    
    transition, which, in turn, has the following negative
    effects:
    
     1) Credit1 counts that as a wakeup, and it BOOSTs the
        vCPU, even if it is a CPU-bound one, which wouldn't
        normally have deserved boosting. This can prevent
        legit IO-bound vCPUs to get ahold of the processor
        until such spurious boosting expires, hurting the
        performance!
    
     2) since the vCPU is fails the vcpu_runnable() test
        (within the call to csched_schedule() that follows
        the wakeup, as a consequence of tickling) the
        scheduling rate-limiting mechanism is also fooled,
        i.e., the context switch happens even if less than
        the minimum execution amount of time passed.
    
    In particular, 1) has been reported to cause the following
    issue:
    
     * VM-IO: 1-vCPU pinned to a pCPU, running netperf
     * VM-CPU: 1-vCPU pinned the the same pCPU, running a busy
               CPU loop
     ==> Only VM-I/O: throughput is 806.64 Mbps
     ==> VM-I/O + VM-CPU: throughput is 166.50 Mbps
    
    This patch solves (for the above scenario) the problem
    by checking whether or not it makes sense to try to
    migrate away the vCPU currently running on the processor.
    In fact, if there aren't idle processors where such a vCPU
    can execute. attempting the migration is just futile
    (harmful, actually!).
    
    With this patch, in the above configuration, results are:
    
     ==> Only VM-I/O: throughput is 807.18 Mbps
     ==> VM-I/O + VM-CPU: throughput is 731.66 Mbps

    x86: make compat_iret() domain crash cases distinguishable
    
    Rather than issuing a (mostly) useless separate message, rely on
    domain_crash() providing enough data, and leverage the line number
    information it prints.

    libxlu: avoid linker warnings
    
    Recent ld warns about libxenlight.so's dependency libraries not being
    available, which can be easily avoided by not just passing the raw
    library name on ld's command line.
    
    In the course of checking how things fit together (I originally
    suspected the warning to come from the linking of xl) I also noticed a
    stray L in SHLIB_libxenguest, which gets removed at once.

    drop get_xen_guest_handle()
    
    Its use in the tools (and its apparent abuse in the hypervisor) are
    long gone.
