Measure WaitLatch's timeout parameter in milliseconds, not microseconds.

Browse Source 
The original definition had the problem that timeouts exceeding about 2100
seconds couldn't be specified on 32-bit machines.  Milliseconds seem like
sufficient resolution, and finer grain than that would be fantasy anyway
on many platforms.

Back-patch to 9.1 so that this aspect of the latch API won't change between
9.1 and later releases.
