Rename function
More easily read math
merged functions together
Changed from predefining error
Fix empty string issue
use same function for max mem store
This allows stream placement to overflow to adjacent clusters.
We also do more balanced placement based on resources (store or mem). We can continue to expand this as well.
We also introduce an account requirement that stream configs contain a MaxBytes value.
We now track account limits and server limits more distinctly, and do not reserver server resources based on account limits themselves.

Along a leaf node connection, unless the system account is shared AND the JetStream domain name is identical, the default JetStream traffic (without a domain set) will be denied.
As a consequence, all clients that wants to access a domain that is not the one in the server they are connected to, a domain name must be specified.
Affected from this change are setups where: a leaf node had no local JetStream OR the server the leaf node connected to had no local JetStream.
One of the two accounts that are connected via a leaf node remote, must have no JetStream enabled.
The side that does not have JetStream enabled, will loose JetStream access and it's clients must set `nats.Domain` manually.
For workarounds on how to restore the old behavior, look at:
https://github.com/nats-io/nats-server/pull/2693#issuecomment-996212582
New config values added:
`default_js_domain` is a mapping from account to domain, settable when JetStream is not enabled in an account.
`extension_hint` are hints for non clustered server to start in clustered mode (and be usable to extend)
`js_domain` is a way to set the JetStream domain to use for mqtt.

The nonce feature is useful to custom authentication plugins
but at present there is no way to enable a nonce to be presented
other than by setting nkey accounts etc.
This enables the nonce to always be presented in those situations.
Since its primarily useful to embedded scenarios there is no corresponding
configuration file behavior for this flag.

* Redact URLs before logging or returning in error
This does not affect strings which failed to parse, and in such a scenario
there's a mix of "which evil" to accept; we can't sanely find what should be
redacted in those cases, so we leave them alone for debugging.
The JWT library returns some errors for Operator URLs, but it rejects URLs
which contain userinfo, so there can't be passwords in those and they're safe.
Fixes#2597
* Test the URL redaction auxiliary functions
* End-to-end tests for secrets in debug/trace
Create internal/testhelper and move DummyLogger there, so it can be used from
the test/ sub-dir too.
Let DummyLogger optionally accumulate all log messages, not just retain the
last-seen message.
Confirm no passwords logged by TestLeafNodeBasicAuthFailover.
Change TestNoPasswordsFromConnectTrace to check all trace messages, not just the
most recent.
Validate existing trace redaction in TestRouteToSelf.
* Test for password in solicited route reconnect debug
Authentication token has never been supported for cluster and
gateway (and leafnode). There is not even a Token option in
ClusterOpts or GatewayOpts.
However, the parsing of the configuration was not rejecting this
misconfiguration, making users believe that token was used for
authentication.
Documentation will also be fixed since it is reported there that
token is supported, which again, has never been the case.

The RootCAs was not properly set, which could prevent the server
to create a TLS connection to the account resolver with an error
such as:

This is related to PR #2407. Since the 64MB pending size is actually
configurable, we should fail only if max_payload is greater than
the configured max_pending. This is done in validateOptions() which
covers both config file and direct options in embedded cases.
The check in opts.go is reverted to max int32 since at this point
we don't know if/what max_pending will be, so we simply check
that it is not more than a int32.
For the next minor release, we could have another change that
imposes a lower limit to max_payload (regardless if max_pending
is higher).

* [added] pinned_cert option to tls block hex(sha256(spki))
When read form config, the values are automatically lower cased.
The check when seeing the values programmatically requires
lower case to avoid having to alter the map at this point.

This allows a domain to be set in the JetStream server block that sets a domain name.
Once set this signals that any leafnode connections should operate as separate JetStream domains.
Each domain <NAME> is accessible via "$JS.<NAME>.API.>", even when connected to the same domain.
Also for mixed mode you can set a jetstream block now that defines a domain but specifies "enabled: false".

If running the server with command lines:

the default ciphers would not be set, however, they would using this
equivalent config:
```
tls: {

key_file: "key.pem"

* [fixed] issue where verify_and_map: true in leaf node config was not used
This broke the setup in such a way that any connect relying on this would have failed.
This also fixes an issue where specifying no account did not result in using $G.

This will allow a better experience if there is a load balancer

Added two options in the remote leaf node configuration
- compress, for websocket only at the moment
- ws_masking, to force remote leafnode connections to mask websocket
frames (default is no masking since it is communication between
server to server)
