LGTM - but let's have Ivan eyeball too. Also feel free to squash.

Some changes needed, especially to prevent panic.
Also, it means that all clients would need to be updated to support this pagination options in the StreamInfo() API, right?

Yes, the clients need to be updated to be able to leverage pagination. As soon as this is merged I can create PRs (I already have the coding done) for natscli, jsm.go and nats.go (I can probably have a go at Java as well).
Existing clients still work (these changes are backwards compatible) though obviously then can only get the first 100k subject details

[CHANGED] StreamInfo() will now return all subjects when requested
65796fc 
If a subject filter is specified in the StreamInfoRequest{} option,
then all matching subjects will be returned and not be capped to
the server limit of 100,000. It is internally using pagination
that was added in the server PR: nats-io/nats-server#3454
