Introduce vNULL to use as a nil initializer for vec<>.

This patch implements Jakub's idea of adding an empty struct with
a typecast operator that returns nil vectors.  This is useful to
shorten all the initializers when declaring vec instances or passing
nil vectors as function arguments.

Convert vec<> into a POD.

This fixes PR 55398 by making vec<> a true POD.  I thought we could get
away with having private fields, but we can't.  We fail to pass vec<>
instances through varargs.

The patch makes every field public and mangles the field names in the
hope that no future patch will try to make use of them directly.  It's
horrible, but I could not think of anything better.
