This macro is identical to NS_INTERFACE_MAP_END and encourages the
reader to think that there's something extra-special threadsafe about QI
implementations that use the macro, when in reality there's nothing of
the sort.
We must close cache iterators before shutting down CacheIndex because they hold reference to CacheIndex which causes that CacheIndex is not destroyed when it's dereferenced in CacheIndex::Shutdown.

CachePerfStats gathers performance data for single open, read and write operations as well as the whole cache entry opening. It maintains long term and short term average. The long term average filters out excessive values and it represents and average time for a given operation when the cache is not busy. The short term average represents the current cache speed. By comparing these two stats we know pretty quickly that the cache is getting slower and then we race the cache with network immediately without a delay. Otherwise the delay is based on the average cache entry open time.

When overlimit eviction is too slow the new content might be stored much faster than the old one is deleted. In such case the cache can grow far beyond the cache size limit. This patch implements a hard limit (105% of cache size limit) when we stop caching any new content.
This patch makes most Run() declarations in subclasses of nsIRunnable have the
same form: |NS_IMETHOD Run() override|.
As a result of these changes, I had to add |override| to a couple of other
functions to satisfy clang's -Winconsistent-missing-override warning.
