Fixes ADB crash on Windows due to large number of connections.

The reason for the crash is that ADB on Windows uses WaitForMultipleObjects to
wait on connection events. When number of connections exceeds 64, ADB crashes,
because WaitForMultipleObjects API doesn't support more than 64 handles. This
CL contains a fixer routine that allows waiting on an arbitrary number of
handles.
