Log Message:
-----------
Add dualvar-creating newSVpviv and friends
These two new functions and one macro create PV-and-IV dualvars, in
similar style to the other newSV*() family.
They are most convenient for wrapping error values from external
libraries, to create dual number/string values in a similar style to
core's $! wrapping of errno.
For example:
int err = uv_...();
if(err != 0) return newSVpviv(uv_strerr(err), err);
This makes the usual style of error-type dualvar that can both be tested
for numerical equality and additionally used as a string to yield its
human-readable error message
croak "Unable to complete: $err" unless $err == UV::UV_EAGAIN;
