Tracking HWND creation/deletion

This CL adds macro used to track the creation and destruction
of HWNDs, in an attempt to detect potential double-delete.
A double-delete of a HWND might be responsible for the crasher

Note: this CL was previously committed and reverted because it broke the sandbox integration module.

Sky, this is the same CL that you reviewed earlier on.
It was breaking a sandbox module view because it introduced a new dependency in
win_util to ICU.
Changes in time.cc and stats_table.cc remove that dependency.

Jim, let me know if you are ok with the changes to time.cc and stats_table.cc.

The changes to the stats_table.cc LGTM.  I didn't review the  rest.
