Revert "Convert contrib/seg's bool-returning SQL functions to V1 call convention."

This reverts commit c8e81afc60.
That turns out to have been based on a faulty diagnosis of why the
VS2015 build was misbehaving.  Instead, we need to fix DatumGetBool().

* Declarations for SQL-visible functions.
*
* Note: many of these functions have intentionally been left using V0 call
* convention, as a means of testing that that still works. However, we had
* to convert functions taking or returning float4 to V1 convention, as it was
* otherwise too painful to deal with both pass-by-val and pass-by-ref cases.
* Also, on some modern platforms V0 functions returning bool do not work
* (because the compiler doesn't ensure that high-order bits of the
* pointer-sized result are zeroed), so those have been converted to V1 also.
