This makes configuration files that are empty, or read and processed
by the parser but with no detected values now return an error.

Do not hold onto no interest subjects from a client in the unlocked cache.
If sending lots of different subjects all with no interest performance could be affected.

Three issues were found and resolved.
1. Some purge replays after recovery could execute full purge.
2. Callback was registered without lock, which could lead to skew.
3. Cluster reset could stop stream store and recreate it, which could
lead to double accounting.

When a lazy simple state has an outdated first that needs to be updated,
if fseq had moved past it would panic.
This was not common but with latest fix prior in can become more common,
hence why it showed up.

This is a fix for a bad msg blk detected in the field that had sequence
holes.
The stream had max msgs per subject of one and only one subject but had
lots of messages. The stream did not recover correctly, and upon further
inspection determined that a msg blk had holes, which should not be
possible.
We now detect the holes and deal with the situation appropriately.
Heavily tested on the data dump from the field.

Previously the Total in paged responses would always equal the size of
the first response this would stall paged clients after the first page.
Now correctly sets the total so paging continues, improves the test to
verify these aspects of the report

If we created lots of hashes, beyond server names, like for consumer or
stream NRG group names etc, these maps would grow and not release
memory. Performance hit is ~300ns per call, and we can use string intern
trick if need be at a future date since it is GC friendly.

In the benchmark on my machine, this added ~300ns per call, but I think that is ok for now vs the memory usage.

When service imports were reloaded on active accounts with lots of
traffic the server could panic or lose data.
