- Added non-public stream and consumer configuration options to
achieve the "no subject" and "no interest" capabilities. Had
to implement custom FileStreamInfo and FileConsumerInfo marshal/
unmarshal methods so that those non public fields can be
persisted/recovered properly.
- Restored some of JS original code (since now can use config
instead of passing booleans to the functions).
- Use RLock for deliveryFormsCycle() check (unrelated to MQTT).
- Removed restriction on creating streams with MQTT prefix.
- Preventing API deletion of internal streams and their consumers.
- Added comment on Sublist's ReverseMatch method.

MQTT streams are special in that we do not set subjects in the config
since they capture all subjects. Otherwise, we would have been forced
to create a stream on say "MQTT.>" but then all publishes would have
to be prefixed with "MQTT." in order for them to be captured.
However, if one uses the "nats" tool to inspect those streams, the tool
would fail with:
```
server response is not a valid "io.nats.jetstream.api.v1.stream_info_response" message:
(root): Must validate one and only one schema (oneOf)
config: subjects is required
config: Must validate all the schemas (allOf)
```
To solve that, if we detect that user asks for the MQTT streams, we
artificially set the returned config's subject to ">".
Alternatively, we may want to not return those streams at all, although
there may be value to see the info for mqtt streams/consumers.

When a system account was configured and not the default when we did a reload we would lose the JetStream service exports.

Made several changes based on feedback.
1. Made PubAckResponse only optionally include an ApiError and not force an API type.
2. Allow FilterSubject to be set on a consumer config and cleared if it matches the only stream subject.
3. Remove LookupStream by subject, and add in filters for stream names API.

Allow an API endpoint and public API to lookup a stream by subject. The subject needs to be an exact match or a subset. If the subject is considered a filtered subject for the stream that will also be returned.

When purging an empty stream success is true but the
purged is then omitted since its, correctly, 0. It's
better to include it even when zero so it's not weirdly
inconsistent between succesful purges.
Also helps with validation of payloads

This also introduces the ability to have flow control inbound for restoring a stream.
If the system detects a reply subject it will respond with a nil payload.
For the last EOF message if a reply is present it will respond with a stream info response or error.

We now publish advisories when streams and consumers are added,
deleted and modified
Also rework how TypedEvents are created to be easier to use

when go json marshal a unset []string it puts
null in the body and not [] which then makes
it an invalid list of strings.

Also standardise some names of response structures and create
reusable types that can be included into others to construct
our standard API requests and responses.
Fixes some json tags.
Updates the design document of the JSON responses to reflect
the implementation that was done

API still only turned on for account info in disabled accounts. Issues with advisories. Plan is still to have all endpoints on in all accounts.
Stream list and Consumer list return names only, page limit increased to 1024.
Stream, Consumer and Template names limited to 256 for now.
Subject API for stream messages, delete and get, not have STREAM.MSG.
Subject API for Durable is now CONSUMER.DURABLE.
Subject API for Templates now STREAM.TEMPLATE.
All subject APIs for list reverted back, so STREAM.LIST, CONSUMER.LIST etc.

API made more consistent. Noun followed by verb.
Name arguments in request subejcts are always at the end now.
Remove enabled call, just use account info.
Getting a message directly from a stream is treated like an admin API and requires JSON request.
Deleting a message directly as well.
StreamList and ConsumerList now include details and support paging.
Streams and Consumers now contain a created field in their info.
