r578 diag: event-function reachability probe (gsp_rm_ev_func)
The r577 A/B (sequence, bNotifyList, hClient) all yielded nv_post_event=0
with every record consumed by the guest: the drop is content-independent.
This knob posts event records with a caller-chosen RPC function instead of
POST_EVENT 0x1003; posting an event whose handler has an unmistakable guest
side effect (UCODE_LIBOS_PRINT 0x100C trips NV_ASSERT_FAILED on an
unsupported ucode; OS_ERROR_LOG 0x1006 logs an errString) proves whether
the guest dispatches our status-queue event records at all - dispatch vs
consumed-without-dispatch decides the next probe (inside _kgspRpcPostEvent
or earlier in the drain).
