Small bugfix in update handling and remove ancient zend hashmap memory leak.

Breaking changes:

• Removed the flush() method: the postpone flag will now only postpone flushing to the end of the event loop queue, instead of never triggering it until flush() or a non-postponed method is called by @danog
• Removed the deprecated getDialogs method, please use getDialogIds instead by @danog

Features:

• Add ChannelParticipant update, received whenever a participant leaves, joins or is banned or admined in a channel or supergroup by @ahjdev
• Add a FilterTopicId filter to filter messages by topic ID by @ahjdev
• Add queueId parameter to methods to allow enforcing server-side execution order when using postpone or invoking methods concurrently by @danog

Fixes:

• Completely refactor message and update handling, improving performance and fixing various bugs by @danog

• Fix BotChatInviteRequest by @danog

• Update the source code of downloadRenameBot.php by @ahjdev

• Report exceptions thrown from event handler to the report peer(s) of the current event handler when using multiple event handler with startAndLoopMulti or EventLoop::queue(MyEventHandler::startAndLoop(...), '...madeline'); by @danog
  Note that for performance reasons, some internal or connection exceptions not thrown from the event handler and exceptions thrown from onStart may still get reported (only to, or also to) the last started event handler.

• Completely remove postponing from the API to avoid unwanted side effects (sequentially queued requests are still bundled in a single container anyway by @danog

• Use async output buffer stream with downloadToBrowser by @danog

• Secret chat media improvements by @danog
