- fix a bunch of minor issues and typos that were found using GoLand
and gosec
- add a gosec Makefile target for Groupware related files, in
services/groupware/Makefile
- enable checking JMAP session capabilities for events and contacts,
and only enable skipping that check for tasks until those are
implemented in Stalwart as well
- fix a CWE-190 (integer overflow or wraparound) found by gosec
- consistently use struct references for methods of Groupware and
Request, instead of mixing up references and copies
- always log errors when unable to register a Prometheus metric
* remove the baseurl from the JMAP client configuration, and pass it to
the session retrieval functions instead, as that is really the only
place where it is relevant, and we gain flexibility to discover that
session URL differently in the future without having to touch the
JMAP client
* move the default account identifier handling from the JMAP package to
the Groupware one, as it really has nothing to do with JMAP itself,
and is an opinionated feature of the Groupware REST API instead
* add an event listener interface for JMAP events to be more flexible
and universal, typically for metrics that are defined on the API
level that uses the JMAP client
* add errors for when default accounts cannot be determined
* split groupware_framework.go into groupware_framework.go,
groupware_request.go and groupware_response.go
* move the accountId logging into the Groupware level instead of JMAP
since it can also be relevant to other operations that might be
worthy of logging before the JMAP client is even invoked
* implement more metrics, in a more streamlined fashion
* use concurrent-map to store SSE streams instead of a regular map with
one big lock that will not scale when it grows, causing too much
contention on that one lock
* while testing error metrics, noticed a few bugs with error handling
when Stalwart is down: fixed
