ben ingram 73961fa70d Updates to FileCache to work better with shader preloading ...

- FileCache can dynamically allocate/release memory as needed
- Preloaded lines are locked in the cache.  One the preloaded memory has been read, the line is unlocked.  This prevents preloaded lines from being evicted before they're needed.
- Cache line size changed from 64k to 16k, reduce fragmentation due to locked preloaded lines
