Use VXS_ prefix for XSUB bodies in CPAN version

The names of the functions in core and in the CPAN version will con-
flict otherwise.

Since perl versions before 5.16.0 did not have XS_INTERNAL (which
could solve this problem another way, making the functions static),
it’s easier just to use different names.
