Description Chris Dumez 2015-03-15 17:49:08 PDT 
Make DatabaseContext suspendable if there is no pending database activity, i.e.
- Pending Database creation JS callback
- Pending transaction(s)

Suspending is safe in this case because we are not going to interrupt any database activity, nor fire any JS event.

This will greatly increase the likelihood of pages using websql to enter the PageCache.

This broke Windows tests because Windows does not support this feature.
