Bug: 160971853 Reduce the auto-cork delay from 2s to 50ms. Testing shows that this introduces a very few new invalidate calls for the package_info cache key, and greatly improves the hit ratio for the associated caches. This change includes a fix to the cache-clear counter. Some clears were missing. Test: * phone reboot * atest CtsContactsProviderTestCases * atest FrameworksServicesTests:UserSystemPackageInstallerTest * atest FrameworksServicesTests:PackageManagerSettingsTests Verified that hit ratios improved over the baseline. Verified that the number of extra invalidates did not increase by more than 5. Change-Id: I4b70b1da8c3927c74077e6da0e60dc56c2e007f1
