This seems not only wasteful but genuinly has the risk someone makes
their device useless by accidentally adding a huge file.
This also re-structures the checks a little: The if-conditions are
flattened out and cheap checks are done before more expensive ones.
* (r10s, adb, hpk) remove getAllUpdates() and add a typical replica-API that works with increasing serials. Streamline docs a bit.
* adapt ffi to new api
* documentation: updates serials may have gaps
* get_webxdc_status_updates() return updates larger than a given serial
* remove status_update_id from status-update-event; it is not needed (ui should update from the last known serial) and easily gets confused with last_serial
* unify wording to 'StatusUpdateSerial'
* remove legacy payload format, all known webxdc should be adapted
* add serial and max_serial to status updates
* avoid races when getting max_serial by avoiding two SQL calls
* update changelog

this uses `get_webxdc_info().name` for chatlist etc.
the previuosly used static strings comes from a time
where we just did not had the correct name.
i was also thinking about adding `get_webxdc_info().summary`,
however, as this information is dynamic,
that may open several issues, eg. quoted text may change
so that the answer is out of context.
as discussed in dev chat,
100 kb is too low if one wants to use any game framework.
also, many game that doesn't have poor graphics
or uses magic CSS-tricks to do fancy draws,
will have more than 100 kb probably just in tiles and sprites.
even for regions with low resources,
100 kb is low for a game -
esp. if we compare that with stickers that are send around as well
are not deduplicated and also have several 100 kb in size -
for much less effect.
we should still encourage ppl to create tiny apps,
however, a too low limit also restricts possibilities wrt adaption.
already before,
we did _not_ sent updates to contact requests or other read-only-chats.
however, we _did_ modify the local database,
so that getAllUpdates() returns an update that was not sent out to other peers.
this is fixed by checking can_send() soon.
that way, all peers have the same state
also for contact requests or other read-only-chats
and webxdc in contact requests can be opened as usual.
further ui improvements may be needed for contact requests
(maybe allow the webxdc to know about that state or
maybe show a warning in the ui somewhere),
however, this is not part of this pr.
* let sending invalid webxdc fail
invalid webxdc can still be send as Viewtype::File, however
(maybe one want to discuss errors or so ;)
* clarify the supported zip compression methods
* add a test for unencrypted replies to encrypted webxdc instances
* make update messages work if a key is missing
even in opportunistic chats,
replies to encrypted messages are forced to be encrypted,
if that is not possbile, message sending fails.
while this is okay to not leak previously send text messages,
the quotes as used by webxdc are more artificial,
currently only the static text "Webxdc".
* changelog ...
* fix forwarding webxdc instances, add a test for that
* adapt webxdc test to fail on info-messages added when in draft mode
* do not add info-messages when in draft-mode
* half the number of instance-loads per webxdc update send/receive
the summary can be modified by the apps using
`sendUpdate({summary: "foo", payload: ...})`
the summary is updated when there is no newer update
and chat will be informed by the change as usual by
`DC_EVENT_MSGS_CHANGED`.
additional parameters will be `summary` and `msg` (for an info-message)
right now, and maybe more in the future (`aggregated`, `fast`, `to` ...),
so adding just more parameters easily gets wild.
also, this makes adaptions easier as no ffi needs to be adapted
when we add more parameters.
finally, sending is in-sync with receiving, database and wire now,
one receives similar objects as one sends,
which also looks like the right thing :)
for now, `sendUpdate()` also allows to use the old, unwrapped payload
to not immediately break existing `.xdc`, however, that will be removed soon,
probably before the first release.
