Creates a new SV. A non-zero C<len> parameter indicates the number of
bytes of preallocated string space the SV should have. An extra byte for a
tailing NUL is also reserved. (SvPOK is not set for the SV even if string
-space is allocated.) The reference count for the new SV is set to 1.
+space is allocated.) The reference count for the new SV is set to 1.
C<id> is an integer id between 0 and 1299 (used to identify leaks).
