The error handler is unsafe. Is there a good reason for that?

Semi good reason, the error handler doesn't get the user_ctx like the normal handler does, so this has to be a unique function that gets called
When invoked, the validity of
uri,method,content_lenanduser_ctxfields of the httpd_req_t parameter is not guaranteed as the HTTP request may be partially received/parsed.
It should be possible to work around it with a global Mutex or something else

How am I supposed to use this pub struct outside of esp-idf-svc given that its members are private?

Should most likely not be pub

Is de-registration of these necessary, on server stop?
