Thomas Munro 1e01374654 Fix overflow in Windows replacement pg_pread/pg_pwrite. 
When calling the Windows file I/O APIs there is an implicit conversion
from size_t to DWORD, which could overflow.  Clamp the size at 1GB to
avoid that.

Not a really a live bug as we don't expect anything in PostgreSQL to
call with such large values.
