Http cache: Implement a timeout for the cache lock.
The cache has a single writer / multiple reader lock to avoid downloading the
same resource n times. However, it is possible to block many tabs on the same
resource, for instance behind an auth dialog.
This CL implements a 20 seconds timeout so that the scenario described in the
bug results in multiple authentication dialogs (one per blocked tab) so the
user can know what to do. It will also help with other cases when the single
writer blocks for a long time.
The timeout is somewhat arbitrary but it should allow medium size resources
to be downloaded before starting another request for the same item. The general
solution of detecting progress and allow readers to start before the writer
finishes should be implemented on another CL.
