Here is a patch that implements setitimer() on win32. With this patch
applied, deadlock detection and statement_timeout now works.

The file timer.c goes into src/backend/port/win32/.

The patch also removes two lines of "printf debugging" accidentally left
in pqsignal.h, in the console control handler.
