Filestore specific items. 1. Internal calls to fetch a msg now use a NoCopy version to avoid unecessary allocations. 2. We introduced a last purge time to detect repeated calls to Purge from a client KV PurgeDeletes operation. 3. Access times for cache lifetime management are now from a single ticker updating an atomic every 100ms. 4. filteredPendingLocked now detects non-wildcard filters. 5. AllLastSeqs() is an optimized version to return all last sequences for all subjects. Helpful for KV watchers. 6. Optimized MultiLastSeqs() and allow it to call into AllLastSeqs() when appropriate. 7. Allow multiple tombstones to be written async and flushed all at once. Signed-off-by: Derek Collison <derek@nats.io>
