Merge branch 'quote-file-name' into next

This is required with RouterOS 7.18 now...

Well, probably the change was introduced with one of the
beta versions...

mod/notification-telegram: introduce $GetTelegramChatId

notify on support for Telegram group topics

…akage...

... but keep the workaround for now - just to be sure.

global-functions: $WaitForFile: check that we can get properties

Looks like RouterOS 7.18beta2 brings more breakage. Having a file
available in listing is just the first step now. We also need to make
sure that the file properties are accessible... 🤪

I have seen this taking several tens of seconds at least... 🤪🤪 So
let's just try until we have properties available, or the file vanishes.

Reported as SUP-179200. 🤞

fw-addr-lists: add a collective list in default configuration

Merge branch 'rmdir-rmfile' into next

RouterOS 7.18beta2 comes with some severe issues in file handling,
probably racy conditions. Let's move file (and directory) removal to
functions, so errors can be caught and ignored 🤪 from a central place.

packages-update: ignore available packages

This was introduced with RouterOS 7.18beta2 to list and install available
packages. We do not want to install all of them. 😝

bump required RouterOS version for all scripts

global-functions: $MkDir: create directory directly...

... instead of file inside directory. This requires RouterOS 7.15, so
bumping requirement.
