Disable system suspend while downloading files on win32.
If the system goes into power-save sleep mode while downloading files,
the download fails. So, prevent sleep mode until the download finishes.
This patch introduces a new RAII class to request that the system's
power-save mode be disabled - PowerSaveBlocker.
This is only implemented for win32; other platforms are stubbed out.
This only partially implements bug 25420 it only attempts to handle the
downloading case.
