* the "position" attribute is always set to 0 when using an anchor for
pagination, but it does not accurately reflect the position and thus
we decided to remove the attribute from the resulting object for
clarity
* omit "canCalculateChanges" attribute when its value is "true", which
is going to be the case in 100% of calls against Stalwart
- 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
* add example generator infrastructure, with some examples for pkg/jmap
and pkg/groupware, with more needing to be done
* alter the apidoc Makefile to stop using go-swagger but, instead, use
the openapi.yml file that must be dropped into that directory using
groupware-apidocs (will improve the integration there later)
* add Makefile target to generate examples
* bump redocly from 2.4.0 to 2.14.5
* introduce Request.PathParam() and .PathParamDoc() to improve API
documentation, as well as future-proofing
* improve X-Request-ID and Trace-Id header handling in the middleware
by logging it safely when an error occurs in the middleware
* refactor some pkg/jmap and groupware methods to make more sense from
an API point-of-view
* add path parameter documentation, but automate it by injecting their
definition into the OpenAPI YAML tree that is extracted from the
source code using go-swagger as it is too cumbersome, repetitive and
error-prine to document them in the source code; wrote a TypeScript
file apidoc-process.ts to do so
* add generating an offline HTML file for the OpenAPI documentation
using redocly, and injecting a favicon into the resulting HTML; wrote
a TypeScript file apidoc-postprocess-html.ts to do so
* add more documentation for properties
* fixes after a bit of trial-and-error with go-swagger
* fix email filter marshalling when there are no search criteria
* introduce an apidoc.yml that contains Swagger data and is merged when
generating the swagger.yml from sources
