1. We were holding open FDs longer than we should for consumers causing issues with open FD limits. We now do not hold them open and cap updates a bit better.
2. When doing a stream delete, consumer delete was repeating alot of work that was not necessary, causing longer delays. This has been optimized a bit, still more improvements to be made.
3. We cover all JS under a single export, but that was also trapping GetNext for pull based consumers, and since this was a no-op (is handled at user account level) we were creating alot of garbage service import responses and reverse map entries that had to be garbage collected. We have a fix in to avoind this but still looking for a better one.
4. Still had some lingering references to all exports vs single JS export.

Some of these are quite generic errors that can happen a lot
in normal circumstances so no need to be too noisy about them
Fixes one missed old style Api Error

Allow wider scoped filtered subjects.
We introduce a per subject information tracking to filestore to optimize for large mux'd streams and more efficient filtered consumers.

We were not properly enforcing server limits. This commit will allow a server to enforce limits but still remain functional even at the JetStream level.
Also fixed a bug for RAFT replay that could cause instability.

This made us add forwarding proposals functionality in the raft layer.
More general cleanup and bug fixes as well.

Underestimated the effort to get stream restore working properly in cluster mode.
Some good bug fixes and stability improvments.

We would release locks and call into upper layers when removing a message. The upper layers may call back into the lower layers to get more information, such as the subject.
This fix has the storage updates optionally supply the subject for filtered consumers and fixes the bug of double deletes.

In preparation for clustering we need to have the consumer filestore update state with deltas vs original design.
Signed-off-by: Derek Collison <derek@nats.io>
The original design had a shared filestore write buffer and individual message blocks had a read cache.
This presented some performance and stability issues when lots of reads and deletes were happening to a
message block that was also being written to actively.
This change eliminates the shared write buffer and uses the message block's cache as a write through as
well as read cache and handles partials correctly.

This will track the stream pending state for each consumer.
This code does account for filtered consumers.
