but could cause some security vulnerability reports.

When a consumer is configured with "meta-only" option, and the
stream was backed by a memory store, a memory corruption could
happen causing the application to receive corrupted headers.
Also replaced most of usage of `append(a[:0:0], a...)` to make
copies. This was based on this wiki:
https://github.com/go101/go101/wiki/How-to-efficiently-clone-a-slice%3F
But since Go 1.15, it is actually faster to call make+copy instead.

This was missing since WEBSOCKET allowed connection type is really
used for client connections.
If one wants to limit a configured user to leafnode connections,
including if the connection is over websocket, but does not
want an application to connect over websocket using this user,
this would have been impossible to configure.
The JWT library has been updated to add LEAFNODE_WS and MQTT_WS for
future work.

This change does 4 things:
Refactor to only have one function to validate imports.
Have this function support the jwt field account_token_position.
For completeness make this value configurable as well.
unit tests.

This will cause the server to not trust accounts/user signed by an
identity key
The boot strapping system account will assume the account is issued by
the operator.
If this is not desirable, the system account can be provided right away
as resolver_preload.
[fixes] crash when the system account uses signing keys and an update changes that key set.

Imports in JWT where extended to contain a new filed LocalSubject.
This Change pulls the new JWT library version in.
It was needed as prefix did not exist in the JWT library and the
original field could not be used. The field To has been deprecated.
When LocalSubject is set, service imports can be configured the same way
they are in config. Meaning, no reversal due to the type.
This change also ensures that wildcard references in transforms are only
set in To/LocalSubject. Before, for services, $1 would have to be set in Subject.
