Add two new functions to the shared library API.
ngSpice_Raw_Evt() requests a callback that returns all the
XSPICE events for a specific node that occurred during the last timestep.
ngSpice_Decode_Evt() provides numeric and string versions of
the event data. Also fix some warnings in sharedspice.c.

Event nodes can be plotted with offset by "iplot", like the
digitop option for "plot". Offsets may be explicit or automatic with "-o".
A variable to set the offset is shared with "plot". In plotcurv.c
suppress some warnings that should not apply to event nodes and do
not falsely claim that some vectors have only one x-value.
